Aluminium or steel propeller?
Most boats are supplied with an aluminum propeller as standard. If you are looking for better performance such as top speed and acceleration you should consider a steel propeller.
Good things 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 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 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 option in all cases. In two identical boats with identical engines, the propellers may be of different sizes if the boats are operated with different loads.
