The first step is to determine the proper pitch for your propeller. Then you will need to decide on an aluminum or a stainless steel propeller.
Step 1 - Determining the Proper Pitch For Your Propeller.
What is pitch?
Pitch is the theoretical distance, in inches, that a boat travels forward during one revolution of the propeller.
How do I determine the pitch that’s right for my engine?
