Had a quick run around Cape Cod Bay yesterday with a brand new 4 blade Quicksilver Nemesis 4 blade 12.8" (they call it 13")x17p prop.

Right off the bat she seems to want to plane off faster.
Not sure if the bow rises more initially before the stern comes up but that's what I thought first time up on plane. Just an observation, maybe I imagined it.
Planes good and at a much lower rpm/speed. Can hold plane till about 13 knots on smooth seas at about 3200 RPMS.
Max full throttle was 5000 RPM's on the nose and 31 knots via GPS.
Can cruise happily at 18-20 knots at about 3600 RPM's.
4 blader also grips good in a tight turn, alleviating some of the sliding sensation from moving the motor up two holes I noticed with the old three blade.

So now the question is do I change pitch, or is that pretty good?
I ordered a 4 blade nemesis 13x19p I can try too, but Ill have to pay for it. Or I just run the 17 and call it good. If I go 19 that will lower my RPMS by about 400, correct?
Maybe I should try a 15P?
115 merc likes 4750-5250. So the 17p is smack dab in the middle.
They don't make a 16 which would probably let me get the full 5250.

17P is probably good enough for my needs...
