The hull (and transom) was originally rated for 90 hp Deuce, an 85/115 hp V4 weighs in (about the same I think) around 280 something pounds with manual trim, 318 lbs (or something close) with Power T&T. There's not much difference in weight really, and IMHO the torque would be a similar equation. (Not that far off.) Since we're going back with fresh wood, and 'glassing it in properly (probably better than originally done), I don't believe it's going to be an issue. The added "knees" or gussets should help handle the additional HP.
That's what makes this "support group" so great, sharing tips and tricks and previous blunders to help others afflicted with the same addiction!
PS - It
looks to me like the OMC's have a "manifold" (internal passageway?) for the trim fluid running through that part of the mount Jason, I was afraid to drill into it and find out! Someone suggested spacing the motor off the transom to allow it to drain, but the motor is already mounted and the bolts are sealed with thickened epoxy to make sure
no water gets in there. I'm adding another drain hole off to the side.?
