Chrysler 15 foot outboard transom repair and deck replacement

Hey folks.

I figured that after all the help I got from lurking in this forum in figuring out how to fix my boat, I wanted to contribute my experience in the hope that others would find it useful.

So, first some backstory... I had been shopping for a boat and had a lakeside camping trip with friends on my calendar. It turned out to be logistically convenient to check out this boat on the way to the camping trip, but in hindsight, it was obviously a terrible idea strategically. I really wanted to buy the boat and so I was inclined to overlook all kinds of deficiencies. I bought the boat and we had a great time at the lake that weekend, but by the time we were headed home I knew the boat had a soft transom, a rotted deck and a significant leak. I didn't pay much for it, but it wasn't worth what I paid.

The outboard motor was strong, so I explored different approaches to fixing it and for a variety of reasons, settled on pulling out the rotted plywood and replacing it with new plywood. I looked into Seacast and other resin-based approaches, but decided that the inside skin of my transom wasn't strong enough to make that approach practical.

Anyway, I've attached a couple of pictures of the outside of the offending transom and, in my next post, I'll describe how I started the job. I hope this will help some folks.

Here's the overall transom

Here's where the engine bracket has cracked the outer skin

Here's the drain tube where the rotted wood doesn't hold it properly anymore and bathtub caulk that someone tried to fix it with.

Welcome to iboats.

You are going to need (best suggestion) to remove the entire upper cap on the boat and be prepared for a full restoration.

Yep, transom, deck, stringers, and foam will all need to be replaced.

Looks like you have a busy winter ahead of you.

Re: Chrysler 15 foot outboard transom repair and deck replacement

Well, I have to admit that this story is a bit of a prequel, I've already finished the job. I was, unfortunately, way too busy while I was in the throes of it to write about it online. I probably could have gotten even more useful tips if I'd done it then. Still, you guys can be the judges of how well it turned out and what I may have to redo down the road. Also, I hope that I can give others some useful tips or warn them away from shoals.

Anyway, as Bob_VT says, separating the upper cap from the hull was the first step. I'll write about that tomorrow. And jigngrub's crystal ball is right on target, because every bit of plywood from the deck down was rotten.

In the meantime here are a couple more pictures of the boat. I was surprised at how much get up and go the 32-year-old outboard still has. It got this little boat right up out of the water, soft transom and all.

Re: Chrysler 15 foot outboard transom repair and deck replacement

The first step to this job, as Bob_VT points out, is to separate the cap from the lower hull and start tearing things out. So I dived right in. I pulled the rubber middle out of the rub rail to reveal pop rivets, lots of them. I had to drill out more than 150 rivets, both on the rail and under it. This seems like overkill to me, but maybe that's the usual. I probably would have had quite a job pulling the top apart from the bottom, but this boat has apparently been apart before because instead of proper urethane sealant in between it was just bathtub silicone. With a drill and a prybar I was able to get the cap pulled up and forward all by myself.

At this point, I got my first good look at how the transom is put together and how badly rotted it is. The pictures don't do it justice, but here's the crack in the inside skin between the engine bolts.

And here's what happens if I pick at it a little with a screwdriver. It was actually soft enough to pull apart with my fingers.

Please try posting the pics again. I am considering doing a similar project and would like to see what I'm getting into.
