When I replaced Calypso's engine mounts I also needed to improve how the bolts
were fastened to the engine beds. Calypso's engine beds are fiberglass over
wood (for height and width) with a steel bar laminated on top of the wood under
approx. 1/2" of fiberglass.
I was able to go up one size of
Like Joe said, angle iron. The diesel in my 35-1 is mounted on angles
bolted through the rails. 1600 hours and no issues. Another option is
have a shop fabricate a channel and install it over the rails through
bolted.
Look at stainless toggle bolts or Twist-Tee anchor bolts. If you drill the
Yes! That would be a great option as well, if a larger bolt size isn't
possible for re-tapping, then just drill out
enough for the heli-coil of the right bolt size and good to go.

I've not taken one (engine stringer) apart, but in other areas that I
have inspected on mine, there is fiberglass and more fiberglass...
well over an inch thick in some areas. I guess back then they were not
sure how much was enough... You may find
some epoxy saturated plywood...but I doubt
Thanks Jeff that was my other question, what’s under the fiberglass.
Yes I was able to get the bolts out. Good thought on retapping and larger size.

Well that's going to be fun. Have you been able to take the old bolts
out, and is it possible to tap a new thread
next size up? That would be easiest solution. Otherwise, Major
re-construction in your future, I see.
Good news, If yours is like my 30, it is a big mass of fiberglass topped
