Boat seems to cavitate with the trim set anything above 1/4, basicly bottom 1/4 down is ok but if you set it to neutral trim the thing revs its tits off and goes nowhere. Is this normal? Boat runs well enough with it trmmed right down just curious as to why it would cavitate so much as soon as it goes above the 1/4 mark. 4.3 inboard model, any previous owners have any insight would be much appreciated.
Here we go again.
