Prop slip calculator

With the retirement of Scott Reichow at the end of January, Mercury Racing didn't just bid farewell to the manager of its extensive propeller program. The high-performance marine engine and accessories company lost one of the most knowledgeable, dedicated, humble and gracious team members to stroll through the doors of its Fond du Lac, Wis., headquarters..

For those wondering about the 1056 that converts "Inches per minute" to "miles per hour". Trans Ratio = 2.5:1. Prop Pitch = 21.5. RPM = 3500 (we cruise here most of the time) Theoretical speed = 28.5 MPH. Actual speed ~ 23 (at the beginning of the season) slip = ~20% which is close to Rob's 18%.E. ekrysinski · #3 · May 1, 2019. majek m2 prop info. I have an Illusion M2 with a 225 SHO on it and have been experimenting with different props. The original prop that came on the boat is a Solas 9553-143-17 and it would get 5600 RPM good speed with fair to OK hole shot and cruise speed. This prop is a 14.25" diameter 17 pitch.

Did you know?

Many popular 3 and 4 blade props for big outboards range in diameter from 13.75” to 15.25”. Generally, if the diameter is lower, consider the rake of the prop and blade area to determine how it might work in your application and if you might need to adjust your engine height and pitch.Using that calculator plug in 2.33 for your gear ratio,6000 rpm,with around 13% slip. 9-10 pitch will get you one side or the other of 20. But,as hard as your pulling with the 11 pitch I'd drop to a 9. That large dia. prop might do a lil better on slip than that,but toons do throw a lot of aerated water at the prop. Are you trimming it out at all?273. My PB: Between 8-9 lbs. Favorite Bass: Largemouth & Smallmouth. Favorite Lake or River Potomac River. Posted September 27, 2013. Like what Martin said, it may boost MPH by about 1-3 MPH. Just go on Merc website and go to the prop selector section.My slip at WOT is 23.5% (5200 rpm), and cruise is around 21% (3600 rpm). Figure the 24-4x4 would get my slip to maybe 18% and if so I would reach just past the 50 mph I have changed many props many times, have a set or 3x3's in 22, 22 cupped, 24 and 26, and the 22 in 4x4
