Transom Wood Question

[NealLauderman]

I am replacing the transom on my 1648 jon boat. The wood that I pulled out was a solid piece 1.5" thick. I went to the store and bought a non-pressure treated 8x6x2 and cut it down to match the old piece. I was getting ready to put some coats of spar urethane on it and was told that I should get two sheets of 3/4" ply and glue it together and use that for the transom as it will be stronger.

Just an FYI, the transom holds a 25hp Mercury 2stroke. What do yall think?

Thanks in advance for any input.

Re: Transom Wood Question

Hi Neal. You're right that two layers of 3/4" on-PT exterior grade plywood, glued and screwed together are actually stronger than a single piece of 1.5" stock. That being said, because the boat and motor are so small, the difference is negligible. You'll be fine with your current set up, just make sure the wood is sealed and mounted to the hull using stainless steel hardware throughout.

Re: Transom Wood Question

Although you can get by with what you have bought the plywood is inherently stronger because of the cross grains in the plywood layers.

You NEVER use Pressure Treated wood of any kind in an Aluminum Boat!!!

Re: Transom Wood Question

Thanks everyone! I am going to stick with what I have for now since I already bought it and it is a fairly small boat. But I will take it as a lessons learned in the incident I ever do this again

Wood, I said non-pressure treated for a reason

Yup .. I think that kfa just didnt put in the "n" befor the "on-PT exterior grade" .. NON-PT ply I think is what he was saying .

If you're putting back the same as what was there you'll be fine, as long as that's what your boat was built with and not a previous owners "improved" design.

The 2x6 is/was much more economical than buying a whole sheet of 3/4" for 2 pieces of 3/4"x4'x6" pieces.
