Could anyone help me figure out what exact prop i need to put my critchfield 13 feet with a 60 sst motor with 185psi on each cylinder... I would like to have fast speeds but in short courses and I good take off the hole! Please really need some help!
12-12.5 x23 cleaver...tough to find good ones these days...can get a brand new one from Titus but they aren't cheap but they do perform really well. If you can find a good used 12.5 x23 that hasn't been worked much send it to Todd or Thom at Hydromotive Engineering in Ohio, they will work a sweet prop for you. Hydromotive have a dominate Ally and Critchfield that circle race in Canada.
With a 185lb sst60 you should see close to 8k with a 23, will need to run 72-73 jets (depending where you live) with some race fuel
Signature Propellers make several propellers that have worked well, also. We make many propellers in this size range. Most of our propellers seem to end up down SOUTH, up North, Malaysia, Puerto Rico, Brazil ...Tim Hackney of Performance Propellers in Soddy-Diasy, Tennessee has do some tuning on Signature Propellers with good results.Quote:

A few years back when I was getting into these type props, a good friend sent me six old OMC Propellers. They were well used, and were all very different, even though they were all OMC propellers. One had Jeff Brown's name on it and is said SE World Championship Propeller on it. I knew Jeff worked for Flagship Marine in Florida, so I called him. I told him I had a prop with his name one it and could he describe it. He said, It would be about 12 1/2 X 23, but had been made out of 25 OMC prop, that had had 15 splines, but Don Hindrich (DAH>) did was bore the spline out and press in a 13 spline brass piece. I asked Jeff if he mined me calling the prop a Jeff Brown. He said he didn't think anyone knew Jeff Brown anymore and he said he'd be happy to a propeller named after him.
This is a Jeff Brown three blade over the hub and a Jeff Brown 4 blade thru hub. Signature 12 5/8 X 22 Thur Hub. $350 plus shipping.
