Re: Holes in transom. . . .

If I'm sure they won't be used again, I stuff 'em with Marine Tex or use a stainless carriage bolt and washer/nut with a healthy squirt of 5200. The Marine Tex generally makes a nicer looking 'cork' than the hardware. Neither is the "proper" way, I'll bet! :D

You could glue up a dowel, drive it in a little deeper than flush and put a gelcoat patch over it. Never know there was ah hole there.<br /><br />c/6<br /><br />hooty

I think the dowel is the best idea.

Recommend you go to www.yachtsurvey.com and check David Pascoe's guidance on sealing holes, coring, etc.<br /><br />If I remember, he would recommend sealing the edges of the exposed wood/coring of the transom with epoxy. This keeps water from entering the coring from the edge of the drillings. Let the epoxy soak into the coring. When the epoxy hardens, then fill the hole with 5200.<br /><br />Skopje

The proper way, or down and dirty?<br />Of course, you want to maintain the integrity of your transom. If you have time to prep your repair properly (dry it out) than I think the best way is with fiberglass. It gets complicated immediately, (epoxy or synthetic). If I planned on selling the boat, I would get some mat roving, resin saturate it, roll it into a tight tube and shove it thru your holes. When it has almost kicked razor blade the end flush. A light resin “glaze coat” with fiber, and tint if your going polyester and your done. No, it’s never that easy. If your using polyester resin you’ll probably use laminating resin for the plug and surfacing resin for the final glaze (gel coat). Here is a tip for getting a patch to look decent. Apply your material to your well taped off repair area, then take a piece of thick (ice bag) plastic, and lay it over your repair. Work the bubbles out, leave the plastic till it kicks, pull the plastic, and walk away. Personally, I would go for a little epoxy resin, a bolt, a couple fender washers, and some 5200, backing plates if it wasn’t my boat. (I always go the extra if it is not my boat.) Main thing don’t let your transom become a rotten, water logged mess, but I guess you know that…
