Good to consider when choosing a propeller
Check the size of your current propeller. The propeller size is marked on the side of the propeller hub at the end of the propeller hub. For example, 11-3/8 x 12, the first number is the propeller diameter and the second is the propeller pitch in inches.
A change in propeller pitch can increase or decrease engine speed. An increase or decrease of two inches (2") of pitch will typically affect engine RPM by approximately +- 300-400 RPM. Also check the engine manufacturer's recommended rpm range for your outboard!
When purchasing an engine, the engine often comes with a propeller that is rated to fit as many engine/boat combinations as possible. This propeller may not be the best choice in all cases.
Two identical boats with the same engine power may have different propeller sizes if the boats are driven with different loads or if one boat is used for water skiing, for example.
