Hello salty dogs!

First off, I'm none too computer savvy, usually half a sheet to the wind, and am on a super slow connection! Looking at all your threads takes ages to flip through... frustrating! I'll figure the picture thing out later..

Tale starts one year ago....

Sold my last boat(23' Fiber form), loved it, with lots of help from Iboats, and was looking for something more utilitarian. There are too many lakes around here to be limited by the size of yer boat.
My search for the 18' Starcraft my father had when I was a lad couldn't wait any longer, and I settled for this boat. It came from the Okanagan here in British Columbia. The price was right, and I wasn't busy due to spring break-up, so I drove down to get her. Po had died and the boat had been sitting... this old story.
Upon getting it home, and performing an in depth evaluation, I found it to be less of a deal than first thought. I must be the first one to experience this?
Inspecting the slightly overpowering 115 'Tower of power', I found the lower unit housing cracked, parallel to the output shaft.. water? Regardless, a 700 dollar part, plus shipping from Michigan. Whaaat? I did have the unit running, and decided to sell it and re-power her. So I sold that engine for 500 Barnacles,(Briefly considered putting a jet pump on it) and began looking for another... big deal here in "Northern" B.C... not easy to come by on a budget!
Floor was soft, rotten around the ski locker, seats were coming apart at the stitching, top is weathered, brittle and shrunken, transom suspect.. poor maintenance all around, list goes on. Still, a pretty good find for 1800 jolly rogers... trailer was nice!
On one of my daily craigslist searches, I came upon an ad for an 80's mercury.. recognized the retaining wall in the background as a fellow I had done deals with in the past, and called the number. Short story, flew done to the 'big smoke(Vancouver), went to an auction, bought two vehicles, a tin boat on trailer, trials bike, and then this outboard! (had to make the trip worthwhile..damn flight cost me 175 bucks!) Drove most of my finds home, sold everything but the motor and the bike... that is how I roll! So I put it all together, and the hydraulic tilt/trim pump was leaking.. 500 bucks to have rams rebuilt and pump o-rings replaced... ouch! Must be 'northern' prices? So anyhow, I limped it through last season as it was, fishing and tubing with the family... running the bilge pump every 20-30 minutes to keep the water below the gunnels...
Now It needs to be rehabilitated... and that my friends, is where we begin ...

Re: 16' Blue Fin project

So I have been trying to get through threads about boat repairs and god almighty knows you boys can slow me down with the chit chat and pictures of your pretty toys! Hard to nail down procedures plain and simple here! But I am trying...

Here's where I'm at.
I've got Miss-Fortune (that's her name cause that's what she'll cost me) torn to the ribs and stringers...

Re: 16' Blue Fin project

Major obstacles:

Transom has many useless holes. Scheduled to have welded on tuesday.
Knee brace is broken.. due to overpower abuse?
Many rivets loose/broke on transom.
Need to know what is the best way to laminate the two 3/4" marine plywood pieces together, for an aluminum application. From what I removed, there is limited room to re-install. Ie. no fiberglass! Resin only?

Re: 16' Blue Fin project

Today I re-in-forced the stringers, all the rivets but a few were sheared off. Braced the ski locker with alum.angle(Princess auto). Cut the 1/2' plywood to fit.
Cut the new floor out of marine plywood and dry fit. (Bought from Windsor plywood).
Need to wait to spar varnish till weather turns. 5 deg. today.
Measured for deck vinyl.
Called around for rivets and pneumatic anvil for 3/16 and 1/4" rivets. Chieftain auto parts in Prince George.
Canadian tire for 3m 4200/5200.
Marine plus for many parts.
Home Depot for rigid foam, Resin, spar varnish and aluminum primer, Windsor ply wood for vinyl decking and??
Road trip tomorrow...

Should I remove the factory flotation? On the fence at this point, and tomorrow will be the day I have the opportunity to get the blue stuff.

Re: 16' Blue Fin project

See top three holes where angle is broken along bend. Thinking about having welder cut it there and add 1/4" across. I will see tuesday. Lower knee brace rivets broken off, I removed leftovers. Can see the movement on transom...

What are your thoughts here? I plan to keep the boat maybe another year depending on if I find 'The One'!

Re: 16' Blue Fin project

For the love of god can we sticky ONE method of transom repair/lamination for each aluminum and fiberglass applications! If I have to read one more "this is how I do it" thread I will officially have a drinking problem... Can't read 24 pages just for this info...

You should've started reading the forum a year ago and started working on your boat 2 months ago.

Titebond 3 waterproof glue for gluing up your transon plywood. Epoxy resin/fiberglass resin/spar/porch paint to seal the transom. 2 to 3 coats, make sure edges get sealed. I screwed my transom boards together while glue was setting up. Removed srews prior to sealing and made sure holes were sealed with epoxy. Hope that helps and good luck.

Re: 16' Blue Fin project

More then 1 good way to accomplish the same goal IS what makes this forum the best online boat university, anywhere. You are paying for marine plywood, I won't. Partially because it's difficult for me to find w/ in 4-5hrs of my house. There are LOTS of places to get the plywood I used.

Lokonn is mostly correct about sealing the transom, IF you use polyester fiberglass resin you MUST use fiberglass cloth/mat as well. It's likely to crack & fail to keep water out of your new transom plywood. The rest are all good alternatives.

I used epoxy to seal my transom, and wouldn't use anything else. I also plan to use epoxy to seal all the wood in my aluminum boat projects. Many of the aluminum boat project owners use spar varnish/urethane for sealing the transom & any other wood in their projects.

I wouldn't remove any of the knee brace because of the crack. Overlaying an aluminum angle and attaching it thru the transom w/ bolts like it was originally and rivets into the sides of the actual knee brace is sufficient.

Be very careful about having your aluminum boat welded. An experienced aluminum welder can fill & plug holes & make other repairs, but many won't if the repairs are anywhere near a seam. The seams are sealed by the factory w/ some sort of material that can pop & splatter if the aluminum gets too hot. If the sealer is damaged enough, the seam may leak. An inexperienced welder can do more harm then good, esp if the aluminum skin gets work hardened by the welding. Particularly harmful if the knee brace is improperly welded.

14 days, woof-da, that's a push

Unless you have super FANTASTIC welder don't have it welded patching the holes is MUCH better alternative a bad welder can ruin an aluminum boat very very quickly.

As far as sealing goes, the answer is different, if you are keeping the boat and using it for only a year spar varnish it 3 times 6 on the edges and call it a day.


If you are really going to keep the boat Epoxy resin minimum sealed 3 times 6 on the edges topped with a paint or varnish where exposed to sunlight.


I am the king of overly ambitious splash goals, I can basically tell you to do that job properly you need to plan for 60 days at minimum and that is if all temps cooperate.

Re: 16' Blue Fin project

Thanks for the input fellas. Except, where is the faith? Of course there is always room for improvement, we're human!
Sure in a perfect world scenario, in ideal climate, following the proper procedures, with the best of products is the way to go. Sometimes, you just gotta do the best you can! Anything I do is an improvement from what it was, just a matter of being effective.
I'll consider everything said to this point as I push on. But on I go! Gonna rethink welding the transom holes thanks to the input. What is the alternative? Jb weld? I have a plan to repair the knee brace which should work slick.

Re: 16' Blue Fin project

You can skim the transom holes over with JB Weld Marine or Loc-tite marine epoxy after the new transom is installed.

As far as fiberglass and aluminum boat transoms go, forget everything you read about the f'glass boats and their transoms... glass and tin are 2 different animals.

I agree with the above posts about using epoxy resin to seal your wood, both transom and decking. I will also suggest using thickened epoxy resin for the adhesive to bond your 2 transom pieces together, I prefer the SM fairing compound for thickening epoxy resin... but there's other materials you can use such as phenolic micro balloons, cabosil, wood flour, and even talcum powder.

I'd remove all the old floatation and install new, you'll probably find that the old foam is wet and heavy when you start removing it.
