Default Prop clearance specs?

Just out of curiosity. What rpm are you turning at wot with the prop
you have? And what engine do you have?



4100 RPM -- should be 4400-4600
That's in a PERFECT day.. flat water, no weight, etc etc etc.
Hole shot sucks.

5.7 gm based mercruiser (350ci) Alpha1 1.47ratio, 19" pitch 3 blade

Regarding the prop -- yes; I can find a 14" 17pitch prop; but they're on the
cheaper side of performance... When I get into 4 blades, they seem to get bigger
as the pitch is decreased.

I'm sure I'll find it.. the prop shop said they wouldn't charge me much to take
some off the edge if I need them to; so I'll probably go with an aluminum and
have them shave it if needed.
