Welcome to Buckshot Racing #77 free online Prop Slip Speed Calculator! This tool helps you estimate the speed of your boat based on engine RPM, propeller pitch, and gear ratio, taking into account a 10% prop slip.
It's a quick and easy way to calculate your boat's expected performance with a change in the propeller.
Instructions:
Engine RPM: Enter the engine’s revolutions per minute (RPM). This is the speed at which your engine is turning.
Propeller Pitch: Input the pitch of your propeller in inches. This is the distance the propeller would move forward in one full rotation, assuming no slippage.
Gear Ratio: Enter the gear ratio between your engine and propeller. This is the ratio of how many engine turns it takes to rotate the propeller once.
Once you’ve entered all values, click the "Calculate Speed" button to see the estimated speed with a 10% slip factor. The result will be displayed in miles per hour (mph).
