Horse Power

Second thoughts:

Given the overall age of the hull, and the fact that it had a shot transom that needed to be repaired, and that even IF repaired correctly has still sufferred flexing and fatigue of the original glass during the time prior to the repair as the transom was rotting, and the fact that you really don't know if the rot extended into the stringers ...
I would not put more than a single 150 (with a 9.9 kicker) on this hull. I feel that in most cases a 150 is the best single hp motor for a v20, anyway. The 140 is a crummy short lived motor because they are trying to pull 140 hp out of a 4 cylinder block. Those motors with the 25 inch legs were taken off an offshore runner and given their age - one or both are on the way out. I would sell them and buy a 150 and a 9.9 kicker.
