This useful calculator computes the speed-of-advance of a propeller based on: engine crankcase speed in RPM; engine gear reduction RATIO expressed as n :1; and. propeller PITCH, in inches. The potential boat speed is then calculated from the speed-of-advance using SLIP, a percentage of lost speed, and unit conversion to boat speed in ...Prop Slip Calculator; Used Propeller List; Contact BBLADES Today!

I just ran the numbers for my 4 blade 10X12 aluminium prop, WOT 5780 rpm at 27 mph and theoretical top speed is 30.55 mph and using the same formula, prop slip is 11.62 %. So maybe going by how my boat feels to drive with the SSP and aluminium props, the prop slip of 6.667 % for the SSP prop is correct.

Slip is the difference between actual and theoretical travel through the water. For example, if a 10-inch pitch prop actually advances 8-1/2 inches per revolution through water, it is said to have 15-percent slip (8-1/2 inches is 85% of 10-inches). Similar to the airplane wing, some angle of attack is needed for a propeller blade to create thrust.Also what is this slip with the prop everyone keeps posting calculations of? alldodge Supreme Mariner Moderator.

Every…The propeller accelerates and rotates the wake of the hull to the rudder. The rudder works in the propeller slipstream, inducing maneuvering forces and moments. The upstream propeller affects the rudder induced maneuvering force while the presence of the rudder influences the propeller generated thrust and the required torque .We have found manufactures published weight to be unsuitable for these calculations.

Took boat out today for first time - 24ft searay 220 1974 with ford 351. Currently have a 17p prop on. at 2500 rpms on a 1.3 ration (mc-1?) we were doing about 18-19 mph - I entered that into some online calculators and it told me slip was 36%?!! That seems incredible - only a cruiser / fish boat - nothing manic. There is a 18" prop under the seat - or shd i go for 19?Prop Talk - Best prop slip calculator? - Might be a dumb question but is there a calculator on the net for your particular setup? I.e. brand, length, average load... Something that pertains more to Fountain than other boat? I'm just looking for the most accurate results without having an actual module on board. Thanks

Find your propeller slip. Use this calculator to figure out just about anything in regard to propeller, ratio, RPM and speed. You can change one parameter and recalculate the rest. Use the CalcT button to figure the theoretical speed from the actual speed and slip.This calculator is free to use as often as you wish. The calculations and results are based on imperical data and formulas. The results are only as acurate as the data you enter. The calculated propeller sizes are based on standard propeller designs; 2 blade = 30% blade area ratio. 3 blade = 50% blade area ratio. 4 blade = 69% blade area ratio.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.

Propeller Slip happens because the propeller is in a fluid (water), and the fluid has viscous properties. This can also happen in every medium, such as air. The other usual formula to calculate propeller Slip is as shown:Add these all into the calculator and voila, it spits out your prop slip. I find this interesting because I feel like I could have found a more efficient prop for my Suzuki df140 My numbers were: Prop pitch 19 (Aluminum), Top Speed 33mph, Top RPM 6000, Motor gear ratio 2.38.
