prop slip

[egk20a2]

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 !

if you have not, post this is set ups or novice boaters forum, as they will have more help on that then here as this is more mechinical help. as for me if hi rooster tail and chine walk ( you did not say what boat, set back or anything important to your question,) I would measure out of the water prop shaft to pad and then go down 1 inch and then work your way up.

You might post on the Prop forum. But, sounds like you need some cup added for the holeshot blowout and raise the motor to help with the chinewalk.
