How much pos. trim? Might need to trim down a little. I have a 18prov with a 150+ yamaha, 10in. jack plate, and it gets a little scary at 65 to 70. I have to run light to get 70 so it gets up out of the water pretty high and i have to trim down a little . But from my experence short boat+big power = hard to drive on top end.The longer the easier to drive. :D :) :( :o :shock: :shock: :?
