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 bolt by re-drilling and re-tapping. IIRC I did use a heli-coil on several bolt locations. I also had four SS "U" brackets manufactured with the intention to use them to overbuild the engine/boat connection. What I determined was the extra height would mess up the engine/prop shaft alignment enough that I would need to slot the engine beds and inset the "U" brackets. I chose not to do that. I still have the brackets if any lister's are interested.

Removed the two back mounts, looks like they are held in by machine bolts into bed. The front two bolts holding each mount were stripped. Question, anyone else came across this? thoughts on solution to re-fasten/bed the bolts. -Rob Please show your appreciation for this list and the Photo Album site and help me pay the associated bills.
