transom replacement

[here2]

i need to replace the transom on my boat and ideas on what type of wood?

I'm sure you're going to get a bunch of replies saying that you have to use marine plywood. For this application I wouldn't bother. I don't think it's needed. I would just use good quality 3/4 exterior grade BC plywood. Cut two pieces a little bit larger than you need. Then I would get some "Gorilla Glue" or any brand of polyester glue. You're going to need some clamps and good screws. I'd follow the directions on the glue because you're going to have to get both pieces damp and then apply the glue and clamp it very well. I'd clamp as much as you can around the edges and I'd use some good stainless steel screws in the center area. You don't have to go nuts but I'd put a few in.

When the glue is set up you can lay your template on the piece and cut it to size. Again, I'd cut close to the line but leave a little bit and then use a good belt sander to get it to the final size. When you get the piece fit and ready to go I would use a good epoxy resin and coat the ENTIRE piece. Front, back, and edges. This will seal the piece up and it will last for years!

I didn't specify in my reply but I'll do it here. I guess I'm picturing your project being on a smaller boat maybe in the 16' or less range. I don't think I'd try it the way I described on a larger vessel.

I was thinking the same thing, bigger power, I'd think about sticking with marine grade ply.

I did just about exactly what jpollman described about six years ago in a 16 footer, except I used epoxy instead of the gorilla glue. The gorilla glue can expand while it is setting up, and if you don't have it clamped / screwed well enough, it could get some "bulging" and give you an inconsistent thickness.

I replaced a transom on my 1972 14' about 10 years ago. I used 3/4 inch treated ply. I sealed the ends with exterior wood glue which I also used to glue 2 pieces together. I used some stainless Tee nut and bolts also. I painted the entire transom before and after installing it. It is still as good as new and has always been outside uncovered.

Just my 2 cents.

:yeahthat: The subject of treated wood and aluminum has been kicked around here a few different times. Don't use it.

[jpollman]

I agree. That's why just standard 3/4 BC exterior grade ply laminated and then sealed with epoxy works fine. It will last for years and it's much cheaper than marine grade ply.

I did a 16 foot Smoker craft witha 40 merc hanging on the back. Just used treated ply wood with 3-4 coats of primer after it ws cut from the templet. never had an issue with anything not mixing well and it worked like a charm. This was a $2K fishing boat not the Mac Daddy fishing boat.
Your boat may require more or less attention to details.
