The Solas Rubex NS3 model propeller has an RBX-203 loose hub that is supplied with the propeller. The propeller fits in place of the Yamaha K series propeller.
The Rubex NS3 model is a high performance all-around propeller with good performance due to its large blade area.
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. Also 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. A standard propeller may not be the best choice in all cases.
The term standard propeller is a tricky one, as all propellers in the propeller manufacturer's range are in principle standard propellers. Two identical boats with identical engines may have different propeller sizes if they are used with different loads or if one boat is used for water skiing, for example.
