Which prop would you recommended with an Atlas 4" jack-plate?
You're either trimming up to aerate that prop or cavitating badly because you're slipping 8 mph from theoretical speed of 46.1.I'm now running a Powertech SCD4 17 pitch. So far the best I've seen is 38.1 at 5800rpm's, but that was with 3 people with a full load and a 21 gals of fuel.
What kind of numbers are you getting?
Jacked up to 4" and half trimmed. The prop is vented (so that helps on hole shot) and does not cavitate at all. Theoretical speed at 5% slip (which is where I'm at) is 40mph.You're either trimming up to aerate that prop or cavitating badly because you're slipping 8 mph from theoretical speed of 46.1.I'm now running a Powertech SCD4 17 pitch.

You may find you will get better hole shot and overall fuel economy with a lower pitch prop that isn't slipping.
According to the calculator 32mphCan either of you tell me what speed I should be seeing from my 14P at 5700 rpm?
Cool. I'm doing okay, then, I suppose.According to the calculator 32mphCan either of you tell me what speed I should be seeing from my 14P at 5700 rpm?
