How to Determin the correct propeller size

1. Determine the rpm range your motor is rated to run. This information can sometimes be found in your owners manual. If not, consult the manufacturer they should be able to tell you.

2. Now test run your boat at wide open throttle with an existing propeller being careful not to exceed the manufacturers recommendation. If your rpm's are too high, you need to go up in pitch. If they are to low, you need to go down in pitch. For every 1" increase in pitch typically results in 150-200 rpm's lower. A 1" decrease in pitch will gain about 150-200 rpm's. With this information you can determine the correct size.
