Prop slip calculator.
Divide by 5280 = Miles per minute, multiply x 60 = miles per hour. This can be shortened to (Pitch x RPM) / (Reduction x 1056) = MPH. Slip is figured by comparing this theoretical speed to the actual measured speed. By the way, for these calculations, add 1" to the pitch if your prop is cupped. (Just about all hi-performance props are)

The SpitFire X7 is the first propeller for 40 hp CT – 125 hp outboards manufactured with Mercury’s proprietary X7 Stainless Steel Alloy, providing additional strength and durability. The Propeller Slip Calculator can be used to calculate two important numbers - Propeller Slip Range and Desired Propeller Pitch. To calculate your slip percentage: Enter your GPS verified top speed; Enter your drive’s gear ratio; Enter your maximum achieved RPM; Enter the pitch of your current propeller.From memory having the tip speed running at 1-3 times the the air flow speed is not efficient, but at least the propeller works over a wide range of air speeds. Highly tuned propeller tips are moving at 6x the air speed. However, their effectiveness at moving air disappears rapidly if the air flow is too slow. (The propeller blades are stalled)
