Whats a good Impeller pitch?

[TexasTexas95]

I gotta get a new impeller, so I thought I would try and get the one that would work best for my current set up. I have a 1990 Squarenose Superjet with a dual carbed 760 motor. It has a protec pipe and a protec rideplate. I have a scoop type intake grate.

I want a prop geared towards rec riding with good low end punch but would also like a prop that can utilize some of the high end speed a 760 apparently has. I dunno, I still have not gotten to ride it. I am bummed out.

Been working on this peice of poop for a couple months now and cavitation issues brought all that an abrupt halt for Memorial day weekend. Thanks! crappy stock impeller and thanks! destroyed pump seal you bastard...

Anyway, heres a few pics up her skirt if that helps. I dont know what model pipe I have or what function my ride plate and intake grate will serve in relation to a particular impeller so I thought pics would be best...

my rideplate junk

I might be in the market if you got anything I might need so feel free to hit me up.

Wow, so nobody uses an impeller on their ski?

Remember that impeller pitch number are useful only when comparing impellers of the same brand & model. Hub diameter and blade area vary from model to model.

That said, I had good results with a Skat-Trak Freeride Swirl 13/16 impeller and also with an old school Skat-Trak 9/14.

Clean ski and clean parts, by the way.

A Skat-Trak Freeride Swirl 13/18 pitch would be a good choice with that engine/pipe combo and it would give good bottom end & top speed.

The Solas Concord 13/17 would have better mid range and still give good bottom to top performance.
