My father-in-law has an 1979 Ski-Natique and the wood inside the fiberglass, where the motor mounts to the boat, has completely rotted out. The lag bolts just spin and spin. The other side is fine. He was wondering if there was a way to fix this without pulling the motor? Dump epoxy in the holes etc???? Anyone know a way to get the lag bolts to tighten up with a completely rotted out 2x6 inside the fiberglass? The fiberglass is in perfect condition yet. THANKS!! Tim

I've heard of some people using CPES to repair rotted transoms in I/Os. You might want to do some google searches on it.

However, if the motor mount is rotted then most likely the stringer it is attached to is rotted as well as least to some degree. I had this issue in an older I/O that I owned. The one motor mount was rotted. Also turned out that the stringer was as well for about a couple of feet. I was able to scarf in a new section of stringer and also put in a new motor mount. IMO, the only real repair is to replace the rotted wood with new. Fiberglass is not that hard to work with. Do it right and you will do it once.

I take it you confirmed "completely rotted out"?

That is all the motor mount is, a 2x6? Easy to replace! The one I did was a rather large block of wood that I had to build to shape because it was not a common wood size, was multi-angled...
