19' fiberglass bass boat with 150 merc. What will be first thing I will notice when I get the eng. too high. I've been raising it a little at a time & nothing seems to change. Nose goes quite high on take off then plains off nicely, I'm thinking the higher the eng. the less the nose will lift. Right now cavitation plate is appx. 2" above bottom of boat with no adverse effects, no blow out, no porpoiseing, no big rooster tail, good water pressure. What will be the first thing I should notice when it starts to get too high?? Thanks
