Transom

[Tinman]

Working on my transom for my alumacraft model f. Is it advisable to put a piece of metal over the inside transom wood where the screw clamps contact ? I was thinking to keep the wood from crushing. Thanks.

It makes sense to me – Some 1/8″ aluminum or stainless steel, where the clamp is.
It would stop the point wear from the clamps, as well as help spread the load.
Just don’t use pressure treated wood – But you knew that ….

Sure did! Oak on the outside and marine plywood on the inside. All coated with spar urethane and stainless fasteners.

when I redid and raised a transom to 20 inches …..years ago for my Merc Is used some bar stock U channel (appox 1/4 thick)

I notched two ” clamp wide” notches off set from center by about 2 inches

Bolted up the bar stock on the transom under the clamps dead center on the boat’s new wood transom

the two notches .. being off-set allowed me to install the engine on my new transom bracket and I then slid the big guy sideways to center it on the transom bracket

the engine clamps now secured under the remaining “lip” provided extra security in case they ever loosen up a bit

The “bottom” edge can be cut/removed….. on better yet you can use a L channel bar stock or angle bar stock and cut out the notches in the lip. trim down the edge of the lip if to wide

p.s no I did not submit for a patent 🙂

Newbe question:. What’s the issue with treated wood?

[Tinman]

Reacts with the aluminum and eats holes in it.
