Login problems

homer-dohHi folks. Yesterday it  came to my attention that some people have had problems logging in or registering for the site the past couple of months. I’d been wondering why traffic seemed a little slow. I thought it was just the winter doldrums.

Sorry! The problem is fixed now.

What happened is, a few months ago I installed some software that was supposed to block spammers from accessing the site (you’d be amazed at how many spam bots try to register on a daily basis). Unfortunately, in addition to blocking spam, the software ended up blocking a number of of legit logins, both current subscribers and new visitors trying to join the site.

So as of an hour ago I’ve turned the blocker off and it will stay off while I search for a better solution. To those who had issues logging in, you shouldn’t have any going forward. (But if you do, please email me directly and I’ll get you fixed up.)

Here’s to the start of a new boating season. The cool news it that wahoo.seatoad.net now has close to 200 registered members. That’s a lot of Wahoo! owners! Looking forward to swapping info and stories with you all in months ahead.

Out of the water, 2013

photoFinally pulled the boat today. I didn’t have any choice really. The POPYC docks are coming out Saturday and the weather is supposed to turn nasty tomorrow with rain and gusts up to 40 mph. My boat was the last one of the docks by several weeks. With the engine problems I’ve had I was worried about getting it out. The options were to put a small, spare outboard on her or try to run her at the lowest possible speed using her own engine, gears a-clattering, and hope that she’d limp into the launch without something catastrophic happening. I’d initially planned to run her to Zioli’s crude but close-by ramp but found out earlier this week that it was blocked off by wintered boats. The Lynn ramp, a mile away, exposed, and with no place to tie up, by myself without help, was out of the question. That left Tim H’s ramp a mile and a half or so up the Saugus River. It was the farthest of the three and being upriver presented an issue if I didn’t time the tides right. But it was the only option left short of a tow.

The day was nice for November, mid 50s and sunny. Wind out of the west and picking up but not too bad yet. I made it over to the slip around noon, 45 minutes before high tide. The idea of mounting the outboard as a kicker quickly proved a no-go as the transom was 2.5 inches at its narrowest point and the 8 horse I brought along wouldn’t open wider than 2.25. So that meant running upriver on the bad engine, with a chance it’d die somewhere along the way. The thought of causing serious engine damage just trying to move a boat a little over mile was not appealing. That it might also leave me victim to the wind and currents was icing on top. I didn’t like the risk but also didn’t have time to to hem and haw: the tide was near high slack and it was a BIG tide…another hour and it’d be pushing out hard to seaward, meaning I’d have to throttle up just to make headway, something I didn’t want to do given the engine problems.

So I loosed the lines and prepared to get underway. At the last moment I realized I didn’t have a life preserver aboard (I’d stripped the boat of deck gear and removed the dock box a few weeks back) so I hunted around in the club dock until I found a kid’s styrofoam boogie board. Not Coast Guard approved but in a pinch it would keep me from drowning.

Pulling out of the slip the engine showed the symptoms that made me releuctant to run it in the first place…on its own it slipped from neutral into forward, and shook and clattered. On the other hand, as it moved along, the problem didn’t get any worse. And with the tide more or less slack and no other boat traffic to contend with we passed under the General Edwards Bridge easily. The half mile to the MBTA railroad bridge was uneventful. Approaching the bridge I eyed the clearance. The eleven foot tide left me five and a half feet. Not much, but enough for my small boat.

The next and last obstacle was the 107/Western Ave Bridge another half mile ahead. This bridge had even less clearance–three feet it looked like as I approached. There’s a drawbridge there but this time of year on a weekday I wasn’t sure it’d be manned. And anyway I hadn’t brought a radio along. If the clearance was insufficient to let me pass I’d have to wait for the tide to drop. And of course with the dropping tide would be the surging current I  didn’t want to fight.

As it was I made it under with about a foot to spare, my head ducked low, looking up at the iron i-beams that even at low speed could likely cave in a skull. Five minutes later I was tied up at the dock. Another boating season over.

Next year, swear to God, one way or another I’m done with problem engines.


Eliminating water in the bilge

Wow, November already. The end of the boating season here in Boston. The weather’s been kind but for how much longer? An oddity–not a single hurricane came up the East Coast this year.

If you’re a regular visitor to the site you may have noticed the lack of posts this summer. Apologies. It was a frustrating season for me and my Wahoo!, although nothing to do with the hull itself. A series of engine problems coupled with a busy schedule kept the boat  out of the water until August. The silver lining is that the extra time the boat spent sitting in the driveway let me tackle some maintenance tasks I’d been meaning to get to. Chief among those was finding and eliminating the leaks from the deck into the bilge.  And I’m happy to say I got pretty damned close. So here’s a write-up.

The Old Water in the Bilge Mystery

Like many Wahoo! owners, I’ve been plagued by water–sometimes a lot of it–showing up in my bilge. The source of the water has been a mystery and a constant topic of speculation among Wahoo! owners. About the only things I knew for sure, because I keep my boat in a salt water slip and because the water in the bilge was always fresh, it that it was  coming in from topside. Any time I hosed down the deck or we got a solid rain I could count on finding a few gallons of water below. Following a three day deluge several years back I must have pumped out at least 40 gallons…that’s 300 pounds of water!

As a quick fix, a couple years back I installed a small pump in the bilge. That gave me a way to get water out. But ultimately I wanted to stop it from getting down there in the first  place. That meant a careful inspection to determine the possible sources of leaks, followed by a whole lot of patching and caulking.

About My Wahoo!

Before getting on to the how-to part of the article, a few points about my Wahoo!. It’s a 1987 16.2 Striper. That’s a 16 foot (thereabouts) tri-hull center console. Several hings about it that may differ from your Wahoo! model:

  • It has a sold fiberglass bench seat. The seat spans the width of the cockpit, separating (as far as deck water is concerned) the front and rear of the boat. A drain hole in the deck just forward of the  seat funnels deck water from the front to the sump basin in the rear.
  • It has a rigging tube located inside the console. There, steering cables and electrical wires enter the console from below deck through a hole in the floor. The rigging tube (really just a six inch PVC lip) sits over the hole. It’s purpose is to keep deck water from getting into it.

Looking for Leaks

Inspecting the boat, I didn’t see any single major source of water incursion. There wasn’t a big crack in the deck, a gaping hole, or anything like that. That suggested  water  was getting in from any number of smaller leaks: the decks drains, the rigging tube, access ports, screw holes, etc.. Going over the boat carefully and methodically and running some tests, here’s what I found:

  • The deck drain system, luckily, did not appear to be leaking. More on this a bit later.
  • I found some small holes I’d never noticed inside the rear storage compartments. there were maybe six in all,  and another one inside the sump basin. It looked like they’d been drilled by a previous owner to mount equipment now no longer present.
  • The rigging tube had a big chunk missing out of it and several smaller cracks, the result of years of cables being fished in and out.
  • Unfastening and then propping up the console, I found that the caulk where it met the deck was in bad shape. Also many of the holes for the securing screws had become enlarged, in some cases two to four times their original diameter, the result of years of pressure on them. Needless to say the screws in those enlarged holes spun freely and weren’t securing anything.
  • Everywhere the caulk looked old and in poor condition (e.g., the access ports, the rigging tube, hardware fittings).

Tips on Finding Leaks

Aside from visual inspection, here are some ideas on how to identify leaks:

  • Storage Compartments: For compartments, one way to test for leaks is to plug any drain holes and then fill the compartment with water. Obviously, if the water goes down, there’s an issue.
  • Rear Cockpit: Because my Wahoo! model has a solid bench seat, I was actually able to eliminate the entire rear cockpit area of my boat as a source of leaks by plugging the drain holes in the sump basin,  filling that area with several inches of water, then looking to see if it went down.
  • Deck Drains: I was lucky in that my boat’s deck drain system did not have any leaks. As a result, I don’t have specific advice on how to fix  your boat’s deck drain  system if its contributing to water in your bilge. (If there’s a reader out there with experience in this and you have advice to pass along, please let me know.)  But here are some ideas on how to at least test the drain system for leaks:
  • Start with a visual inspection of the flanges at the deck drain holes. Look for cracks, gaps, or a loose fit.
  • To test the seal where the flange meets the deck: 1) I plugged the  deck drain hole. 2) I poured about a gallon of water around it. 3) I observed it to see if the water went down.
  • To test for a leak in the plumbing below deck: 1) I started with a dry bilge. 2) I pressed the end of a garden  hose tight against the deck’s forward drain hole and then turned on the water and let it run for a minute or two. 3) I checked the bilge for water.
  • An alternate way to test the plumbing below deck: 1) plug the outlet hole where the deck drain empties into the sump basin. 2) slowly pour water into the the deck drain end until it backs up, indicating the pipe is full. 3) Observe to see if the water in the pipe goes down.
  • On one internet message board a poster suggested a test method that involved pumping smoke into the hull. It sounded too complicated to me, but it may be something you want to research.

The Repair Job

Based on my inspection:

  • I filled the old open screw holes I found in the storage compartments and sump basin using Evercoat Formula 27.
  • I recaulked all of the access ports (my boat has four) and the screws that secured certain deck fittings that I suspected needed it (namely, the fuel fill and the forward anchor locker)
  • I couldn’t find a replacement for the damaged rigging tube so I took it out and repaired it using fiberglass cloth. Then I reinstalled it, caulking well.
  • The enlarged holes for the console-to deck screws I filled using Evercoat Formula 27. Then I redrilled the holes to the size I wanted. I also installed screw anchors in all of the the console holes around, caulking them well as I sat them.
  • I scraped off all of the old caulk at the console/deck seam, cleaned up the area well, and then recaulked all the way around.
  • I found assorted small nicks and chips in the deck. These may or may not have been a source of leaks. I repaired them using either Evercoat Formula 27 or a dab of caulk. Not the most cosmetically perfect solution, but eventually I plan to recondition the entire deck surface anyway.
  • I also went over the console itself, caulking seams and repairing holes that would allow water to get inside, and making sure all gauges were mounted snugly.

That was it. Leaving out the setting time for caulk and the fiberglass cloth, the entire project took maybe four to six hours spread over a couple of days. The only part that was a little bit hard was removing the rigging tube, since that required unhooking all of the cables and wires that run through it. Of course, if the tube had not needed repair but only recaulking I could have done that without taking it out. As it was, I used the opportunity to straighten out some of the wiring inside the console that had gotten messy over the years. If you do need to remove a rigging tube, take careful notes on all connections as you unhook them, what wire goes where. Taking pictures as you go is also a very good idea.

A good caulk tip…that I got from my friend Dave. When caulking a place where two surfaces meet (for example, where an access port meets the hull) let the caulk set awhile before tightening things down. That allows the caulk to form a better gasket, whereas tightening down immediately tends to just squeeze most of it out.


After finishing my repairs (and after all caulk had had a chance to set completely) it was time to test the results. Starting with a an empty bilge I hosed the deck and cockpit down for a solid five minutes. I sprayed in about 35 gallons of water, making sure I got it everywhere on the deck and sides. Prior to the repair work a hosing like that would have put at least two gallons of water in the bilge. And after? The results exceeded my wildest  hopes.Turning on the bilge pump all that came out was about one cup.

In the months since then it’s rained a fair amount and I’ve hosed down the deck many times. Still no water below. The “mystery” of water in the bilge turned out to be a simple one with a simple solution. So if water below has been an issue for you, rest assured that it’s likely an easy fix, not to mention a great winter project for your Wahoo!


Addendum 11/6/14

Pulled the boat from the water today and parked it in it’s winter slip (a.k.a., my driveway). I powerwashed the deck for a solid ten minutes and no water showed up in the bilge. Amazing.


Wahoo! OEM replacement fuel tanks

tankHere’s some great info on where to get OEM replacement fuel tanks for Wahoo!s, passed along by site subscriber Dan Rhodes. Thanks Dan!

I have a 1988 18.50 Offshore. I  just got off the phone with RDS fabricators in Perry Florida and ordered my new 45 gallon aluminum tank! RDS is the same company who made the original tanks, formally AFP, Aluminum Fabricated Products. The tank I ordered is the exact spec tank for my model, down to the location of the fill inlet, vent tube, fuel gauge, and fuel suction. The model # for those of you who cannot read your original labels is 317-45A-AF.

Replacing the fuel tank in a Wahoo! Offshore 1850

1850allWahoo! owner Tom Brennan recently discovered a leak in the fuel tank of his 1989 Wahoo! 1850 Offshore. He’s in the process of replacing it and graciously offered to share his experience. Fuel tank leaks are a common issue in the Offshores, due to their below-deck location and the lack of below-deck air circulation.

So here it is, with lots of great info. Thanks Tom!

(Note: As of this writing (3/17/13), Tom wasn’t completely done with the project (e.g., he hadn’t replaced the deck), so it’s possible this article will get updated with new info.)

Also, for more below-deck and cutaway shots of an 1850, see these great restoration project photos by Joe Bernard.


I live in southern New Hampshire. Prior to owning my Wahoo I had a 14 foot Mckee Craft (Whaler style) that I fished hard. But with three boys and big dreams, I needed a bigger boat. I happened to see an 18 foot Wahoo! Offshore. It was a mess but I knew the design would be perfect for me. So for over two months I hunted Craig’s List from Maine to Florida. Eventually I found a boat in West Virginia that looked promising, selling for just under six thousand dollars. I traveled solo non-stop to see it in person. It was in awesome shape, with a 2001 Yamaha Saltwater Series 150 that ran like new. The title identified it as a 1989 but contained no other information of note. I had it home by Sunday.

Not long after acquiring it I took it for a two week fishing trip on the Ottowa River in Canada. I ran it hard every day with no issues. Great trip–180 fish, 12 species. Wow (i reeled in 3). Returning home, I next took it out in Portsmouth Harbor where we banged around the ocean all day. Back home that evening as I was cleaning up my wife smelled gas. I opened the access ports and the smell was very strong. I knew right then I had a leak. I wouldn’t be taking my kids out in the boat until it was fixed. The tank had to come out.

Getting the old tank out

Now when I bought the Wahoo! I knew it would need a new fuel tank eventually. I’ve changed tanks in a 33 Egg Harbor from that experience know that the constant to moisture over many years will eventually rot pin holes in aluminum (crevice corrosion). However, the way I replaced tanks in the Egg (the right way) is impossible in a Wahoo!.

To replace the tank meant cutting it out of the deck. And the challenge there was figuring out the dimensions of the tank and where to cut. Before doing any cutting, of course, I got every last drop of gas out of the tank. I did not want to remove the whole center console, so I lifted and blocked it as high as the cables/wires would allow.

The final cut

Measuring through the access holes I was able to determine that the tank was 29 inches wide and the drain lines on the floor of the boat centered at 30 1/2 inches. So my first cut would be for width. I laid down tape on the deck and drew my cut lines on the tape. I decided to make the rear width cut first. I wanted it to be as far back as possible, about an inch short of the stringer. (I wanted it an inch shy of the stringer because I planned to later build a two inch ledge for the floor piece to sit back on.)

For the front width cut, I wanted to go as far forward as I could without cutting under the center console. That turned out to be 36 inches from my rear cut. So the dimensions of the opening would be 30.5 by 36 inches.

I made one plunge cut with a vibrating saw and did the rest of the cutting with a jigsaw. The cut didn’t need to be perfectly straight. I’d hoped that 36 inches would be a long enough hole to allow me to  pull tank out. Unfortunately, it wasn’t. In the end I had to cut a section off the back of the tank to get it to come out. To put in the new tank, I’d either have to cut out more of the deck or go with a shorter tank.

The cause of the leak

After removing the tank I inspected it but could not find a leak. In fact, 99% of the tank looked in great shape. So I took it to a local metal shop. At first the repairman there couldn’t find one either but on closer inspection he said, “There it is,” and pointed to a light white ring of haze, rough in the middle., towards the front on the port side.

Later when I got home I looked at the tank cavity and found a dip in the foam that had trapped moisture (possibly from normal condensation) against the tank. Lack of air circulation below deck would have made it difficult for this moisture to dry out. The leak was high enough in the tank that it wasn’t until I took the boat on the ocean that wave action sloshed the gas high enough to reach it. Considering the way the tank is laid in the belly of these boats, foamed all the way down each side and corner, I’d guess such leaks are common over time.

The new tank

The old tank was 45 gallons but I was willing to live with less.I preferred that to cutting more deck. So I had a new one made a bit shorter and shallower (its capacity is 36 gallons). I kept the width of the  new tank 29 inches so it would fit between the stringers. I sanded down the foam on the sides and dry fit it in. It fit by a hair. So I sanded more to create some breathing room on the sides.Prior to installing the new tank I sanded, chemical etched, and painted it with four coats of Rust Bullet Industrial Coating.  I plan on locking it in place with rows of 3M 5200.

The new tank

To support the deck piece, I plan on building a two inch ledge of mahogany/aluminum plate on all four sides for it to sit on. Then I’ll attach it with countersunk screws and cover the screws and seam with 5200.

New downloads and Ray Curry too!

Thanks to subscriber Tom M., the Downloads page now includes three full-page magazine reviews of the Wahoo! 1900 and 2100. Full of juicy specs, test results, comments on construction and performance. Really interesting reading, even if you don’t own those exact models. Thanks Tom! BTW, Tom says he has more that he’ll try to send along so check back.

Also…and how cool is this…I got an email from a friend of Ray Curry, founder of Wahoo! Ray got wind that there’s a Wahoo! owners group and while he’s not into the Internet himself, he’s offered to answer question through his friend via email. So stay tuned.

Source for Wahoo! windshields

Doing some incidental searching I found another source for retro Wahoo! parts. UDP Plastics in Davie, Florida makes replacement windshields for Wahoo!s.

Their list of Wahoo! windshield molds includes:

End of the season

End of the season up here in Boston and I pulled my Wahoo! from the water yesterday. Although I would have hauled out anyway due to the lateness of the season, if I needed any other reason Hurricane Sandy, currently just south of Cuba’s southeast tip, looks like it will  give the US  East coast its first (and likely only) tropical storm of the year early next week.

2012 was my third year as a Wahoo! owner and the best so far. Lots of quality time on the water. Many problems solved, but still no shortage of tweaks I’d like to make to the boat next year. Thanks to the many Wahoo! owners who contribute to and read this blog. It’s been a lot of fun sharing experiences and learning from you guys. Boston Harbor, when the wind and chop are up, can be a pretty rough ride. So three years in I still feel like I’m getting to know this my 16.2′s capabilities, especially in big water. Once thing I know for sure though,  when she planes on a flat surface, what an amazing ride! Like a magic carpet.

This past week my friend Gary C. of Philadelphia was here. Every year in the fall Gary comes up for a short week and we go striper fishing. This year winds gusting to 30 mph kept us off the water much of the time but we managed to have a few nice days and my son Ben (pictured) took his first stripers from my Wahoo!

Now the boat’s in the driveway. Time to get busy winterizing before the cold sets in.

Good fish

While this isn’t a fishing site by any means, I couldn’t let 2012 go by without a single fishing note, especially when I set a personal best in my Wahoo!  :)

Headed out in my Wahoo! this afternoon after work for an hour’s fishing. I was crossing the edge of a large salt water flat when I saw a few small fish (snapper blues, maybe) slashing at bait on the surface. I cut the engine, climbed up in the bow with my fly rod, and started tossing a Gartside Gurgler. As I worked it, about every minute or so something much bigger than the snappers would surge through the bait, scattering it. So I started working the fly with a little more pop and on about the dozenth cast hooked into a good fish. Fifteen minutes later, after a fight that took me well into my backing, I landed the biggest striper I’ve taken on a fly, just shy of 40 inches.

After a few pics and some time to revive her back in the water she went, hopefully next Spring to make a mess o’ baby bass.

Doel-fin magic

Last year I replaced the ancient 1981 Evinrude 50 that came with my Wahoo! 16.2 with a more powerful and reliable 1995 3 cylinder Johnson 50. After the Evinrude, which was hard to start and tended to stall in idle, it was nice to have an engine that started first or second turn of the key every time.  But even with the newer engine I still wasn’t happy with how long it took to get my Wahoo! up on a plane. It took too much throttle to get the nose down. And then once it did come down often the boat was going too fast for conditions (lotsa rocks in Boston Harbor).

So I wanted to be able to plane more quickly, with less throttle, and at lower speeds.  And I wanted to do it without having to increase horsepower. Following the recommendation of a friend, this spring I looked into adding a hydrofoil to the engine. Researching online I found plenty of back and forth on message boards about the relative merits of hydrofoils.

The cons:

  • They reduce overall speed.
  • They weaken the cavition plate, increasing the chance of breakage.
  • They increase drag and decrease fuel efficiency.
  • They catch weeds.
  • Trim tabs are a better solution.

The pros:

  • They will allow you to plane more quickly and at lower speeds.
  • They reduce porpoising and improve handling.
  • The effect on overall speed is minimal or non-existent.
  • They improve fuel efficiency.

And the qualified statements:

  • It depends on the boat. On some they make a difference, on others they don’t. Generally they’re better suited to smaller craft.


Shopping around I found quite a few makes/models to choose from, with prices ranging from $40 to $150. While most hydrofoils require drilling holes in the engine’s cavitation plate (so you can bolt it on), a few of the more expensive models advertised themselves as clamp on/no drilling required. That had some appeal until I read the customer reviews which were generally not favorable.

In the end I opted for Doel-fins, one of the earliest, simplest, and most affordable outboard hydrofoils. I didn’t even have to pay the $40 they cost since I  was able to scavenge a set off a boat that that had washed ashore on a local beach and was abandoned by its owner. Installation was easy. It took less than half an hour and drilling holes in the cavitation plates was not the big deal I feared it might be.

Three months of boating later and the verdict is in: What a difference!!!  I don’t have exact numbers but I would guess that with the Doel-fins my Wahoo! now achieves a plane at 40% less throttle than it took before. And it now planes at speeds as low as 10-12 mph. The ride and handling are smoother, with nice easy turns and a big reduction in porpoising. And my guess (though I don’t know for sure) is that with the faster planing I’m saving quite a bit of gas.

All in all, couldn’t be happier.  :-D
