You can drill the hole oversize and fill with epoxy. Then re-drill proper size hole through the epoxy plug. That should seal the edge grain of the wood. Use 3M 4200 to seal the bolt. That should do it.

A tip I picked up from a boat repair show: When you drill mounting holes for anything, countersink (bevel) the top of the hole about 1/16 inch. The sealer you put on fills the beveled area and acts like an O ring.

Hello!
I am interested more in the epoxy used in transom repair/replace.

What type of epoxy are you using. I can only find small quantities at hardware stores.
I can get a large 2pt mixture at an autobody place, is this the type everyone uses. And is this the same stuff that bonds the wood together for the transom.??
HELP!

As for epoxy, larger quantities are available from online suppliers, the place I used is US Composites. http://www.uscomposites.com/epoxy.html

There are even suppliers available on eBay.
