Aluminium or steel propeller?
Most boats come standard with an aluminium propeller. If you are looking for better performance such as top speed and acceleration you should consider a steel propeller.
Good to know when choosing a propeller
Check the size of your current propeller. The propeller size is marked on the side of the propeller hub or on the end of the propeller hub. For example, 13 x 15, 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 usually affect engine RPM by about +- 300-400 rpm. Check the engine manufacturer's recommended rpm range for your outboard!
When you purchase an engine, it often comes with a propeller called a standard propeller. The size of this propeller is estimated to fit as many engine/boat combinations as possible. The standard propeller may not be the best choice in all cases. Two identical boats with identical engines may have different propeller sizes if the boats are used with different loads or if one boat is used for water skiing, for example.
