I just added a 5.5 cmc jackplate to my 99 285 stratos , I set it to 3.50 below pad , holeshot seems ok but when I trim up about halfway the boat seems to be plowing and spraying at about halfpoint of the boat , speed is about 50@5000rpm . when I trim it up to full trim the boat rides on plane about where it should be, and picks up a little speed/rpm to around 53@5500 rpm . but throws a way high rooster tail about 3 feet over the cowling .
Before the jackplate I was running 50mph@5000rpm at around 4 3/4 below pad . I am running a 23p ss speedzone prop and the motor seems to be running properly . there are usually two people on the boat with a lite gear load .
My question is should I lower or raise the motor to get more top end and cut down on the rooster tail ? I know I am wasting power here somewhere but when I trim the rooster down the boat plows and slows and 53 seems a little on the slow side to me ? any suggestions ? thanks in advance .
