Thanks for your replies right now Im running a 17x19 it is a prop that was on the original motor witch was a 305 top rpm was around 4000 rpm. During the winter I changed out drives from 1.68 to 1.50 ratio my top rpm dropped to 3700.

im not sure just what rpm you should run at wot. but after changing to a v-8 outdrive you may want to go all the way down to a 14.5 x 15 p prop. your rpm,s are way to low. im surprised you can even get up on plane. good luck.
