Spare prop for SSM3 4 blade, 31P 17 3/4 diameter - What is comparable in 5 or 3?
 

I'm looking for a spare set of props for my boat, currently turning the above props (I believe they are Rolla). I dont have any spares, and am looking for a set. If I step up to a 5 blade, what should I look for?
19 spline SSM3....
Running about 3" prop shaft depth.

Boat is a 36' Outlaw-style hull with trannies on the outside (so like an extension box). It is tricky to plane with 4 blades, so dont wann go down to a 3....

19 spline props are getting harder to find. We do sell adapters to go to 26 spline props.
We typically go down a 1/2" in diameter and keep the same pitch when going to 5 blades if you desire to keep similar rpm.

Thanks for the information! What if I stay 4 blade, is there a different pitch or diameter that I use? Like say, I go down in diameter, does that mean I can turn a larger pitch?

Any help would be appreciated.

Maybe.
