A Useful Propeller Calculator Developed By Jim Hebert For Analysis Of Marine Propellers.

Propeller sizing is a fundamental concept in marine engineering, which involves selecting the appropriate size of the propeller for a boat or ship to achieve optimum performance. This calculator computes the propeller pitch of a boat based on the boat velocity (velocity), gear ratio (gear ratio), engine rpm (engine rpm), and propeller slip (slip). When using the mercury prop selector, you can quickly determine the correct propeller size for your boat.
