The plywood screwed on to the back of the transom is looking really tired. It's attached with about 20-30 screws. Should I just unscrew it and put a new one on? Do I fill in the old screw holes with something? The transom is wood.

Re: Transom Question

Hello,again, Tedd.<br /> Luckily, you have an aluminum boat. It's soooo much easier installing a new transom to an aluminum hull as it is to Fiberglass!<br />This is still a tough task,tho.<br />You should try to keep the transom intact as muchas possible while removing it, so you can use it for a pattern.<br />Center-punch the rivets (to keep the drill bit from "walking"},and drill-out the rivets<br /> and remove the screws. It is recommended to use the same materials used in orignal construction, but sometimes, boat builders take short-cuts. So use high quality stanless or brass screws,and aircraft grade rivets. Before setting the transom, seal it with epoxy resin. Use 3M 5200 sealant around the entire seam,and whenever you mount the engine,around the mounting holes,mounting,both inside and out. This is probably where the old transom started it's road to decline (engine/depthfinder mounting holes),with bad sealing.

Re: Transom Question

Like to add..When replacing the rivits.. Dip them in paint (zinc chromate if possible) and then drive the rivits. You will need a aircraft rivit gun and set to do it correctly but they can be driven other ways.

Re: Transom Question

I'm sure I didn't explain it right, but the plywood is attached to the wooden transom, The transom looks in pretty good shape and I think the plywood was added to give the spot where the motor mounts a little extra something. Replacing transoms are little out of league for now...maybe someday. Thanks for taking the time to answer.<br /><br />td

Re: Transom Question

Oh....Ok.I gttcha now. Yes, you will still need to check and repair the transom for rot around any and all holes it has in it.You can replace the plywood with an aluminum plate,which will hold-up much longer.
