Jim I was having trouble with cavitation regardless where I set the trim. As it turns out an 11/2" is the perfect number. Hole pattern on motor is spaced 3/4" apart. So I can raise back to original height or just half way. This new location coincides with
the bottom of the skeg which is close to an 11/2".
So I think this will be the last of the modifications to the back for a while. I will take what I get.
Part of the problem is this is a flat bottom boat. When I built the boat I did not accound for extra glass and epoxy and that is why the motor was a bit high. The whole job only took 2 hours. Next time I will build a lift of some sort so I don't have to go back to the dealer to lift the motor.
I love boats it's building them I can't stand.
