up here in BC the last couple weeks have been unbelievable - all this week, every day - pure sunshine, no clouds. relatively cold -15 C at nite rising to +2 or 3 in the afternoon.<br />This has me thinking about getting back to my trihull I/O rebuild. last fall I put in a new transom (2 layers of 3/4 ply with glass in between and got that glassed in. Also put in the new stringers (not glassed yet) and cut the wood for the engine mounts. The engine (4 cyl, 120hp) has 4 points that are lag screwed into the wooden mounts which are held to the hull with fiberglass. The boat is in position for the engine to be test fitted for final placement and trimming of the engine mounts before glassing.<br />Now I am getting paranoid. The only thing that is holding these wooden mounts down is the fiberglass over top and the weight of the engine. Seems to me that a 120hp engine will exert quite a rotational force on these mounts - how come the lag bolts don't pull out, or the engine mounts rip off the hull. I bought the boat for recreation with kids so waterskiing and tubing are definitely in the plans and I imagine this would put even more stress on the engine mounts. <br />Any re-assuring words? The most reassurance I have right now is that the boat is a late 60's and the engine hasn't ripped out yet....<br />I'm doing the transom/stringer/engine bed/floor replacement because it sat for a number of years with and wasn't covered all that well...
