When selecting a propeller pitch for your boat, it is important that the propeller runs at the upper end of your engines wide-open-throttle RPM range. If you want your RPM's to increase, go down in pitch. To decrease RPM's, go up in pitch.As a general guide, for every 2 of pitch, RPM's will change approximately 400 RPM's. For water sports or extra people on board, you should generally drop 2 of pitch to help compensate for the added weight and drag on your boat.emember this rule of thumb: For every 2 of propeller pitch, rpm's will change approximately 400 rpm's. As you drop in pitch, rpm's increase, and as you go up in pitch, rpm's decrease. So if we want to raise our rpm's we should choose a lower pitch prop.
Boats without tachometers are harder to prop right but if you can at least get the numbers of your old boat propeller that would help us greatly. Aluminum propeller and Stainless Steel Propellers Aluminum propeller are usually the standard prop that comes with the boat when it is new.he first number is the diameter (measured from the prop shaft hole out to one blade tip times two). The second number is the pitch (how far a propeller should travel forward through a solid one revolution in terms of inches).
