Bondo is a poor choice for repairing holes in fiberglass hulls! I'm working on the transom on my mystery 1960ish 14' runabout (see "Where are the stringers?"). Someone in the past must have hit/been hit in the upper starbord rear corner where the transom meets the side. Punched an egg-sized hole in the fiberglass, way up top. They used the new space-age wonder repair material "Bondo" to fix the hole. The plywood in the transom is totally shot. Actually, considering it's 40 years later, the stuff did hold up pretty well. I'll do it differently this time, though.<br />I plan on digging out the old plywood from the top and pouring Seacast. Looks like a good system and this boat is a good candidate for that method. Anyone found an efficient way to get all the old plywood out? Once I got past the first eight inches it got tougher going. The plywood is rotten enough and waterlogged enough that the laminates are spread apart and they just want to flex around down in there. Can't drill 'em, the drill just goes between the laminates. Banging/scraping with a crowbar is getting less and less effective. What works best? Ideas?

Chainsaw might work just fine as long as you keep it under control. Chief ;)

How 'bout a colony of carpenter ants :D Let 'em loose in there and in no time flat you will have a pile of saw dust and it is an environmentally friendly method :D :D

Maybe a sawzall with a long demolition blade? You'd have to be careful not to come through the fiberglass though.

Re: News flash!

brenton26 is right. More than one transom restore done on mfgboats.com with seacast. I recall that a popular tool to dig out the rotten plywood was a piece of 1" or 1.5" round steel stock 30" or so long with the end flattened closed then put on a grinding wheel to make sharp. Search the message forum for more info.
