I am swapping outboards on my boat with an outboard that has a different bolt pattern. What is a good way to plug the old holes? I can't have bolt heads in the way as they will be under the new outboard. These are probably 3/8" holes.
Thanks in advance!

Dole pins out of wood and plenty of 5200 sealer. Then a coating of epoxy on top of them.

Try and get oak dowels as well, not pine.

Agree. Can use epoxy or the 5200, but the hardwood dowel is important. Must be sure to seal the outside of the transom.

BTW, it's a good opportunity to dig around in there a little with a pick or small screwdriver and see if you have some soft wood.

add too that I usually use epoxy so the dowel is soaked along with the surrounding transom wood (actually could even be better if you do that to use a softer wood, in thinking about it, so the epoxy is absorbed better -- think most of the dowels you find are probably hardwood anyway, so maybe moot.....)
