I have a 150 intruder change from 13 1/2 x 23 renegade to a 14 1/2 24 raker prop. Now the prop slip big time right before the boat planes and during trim but grap good during top end. The boat's rooster tail high and chine alot. Should I raise the motor more or lower it. I try raising it and lower it about 1/4" both ways but made no difference. I need help !
