3-Blade vs. 4-Blade MerCruiser Propellers.    
3-Blades
3-blade MerCruiser props are great on most boats as they offer good all around performance, better efficiency, and can achieve higher speeds. Switching from 4 to 3-blades generally requires a 1" pitch increase.
3-Blade vs. 4-Blade
4-Blades
4-blade MerCruiser props work well with bass, pontoon & high performance boats as they provide better acceleration, keep a boat on plane with fewer RPM's, and produce less vibration at high speeds. Switching from 3 to 4-blades generally requires a 1" pitch decrease.

Aluminum vs. Stainless Steel MerCruiser Propellers.    
Aluminum
Aluminum MerCruiser props are a great choice for small and medium sized boats. They are inexpensive and under normal conditions can last for many years. When running your boat in an area where striking the bottom is likely, aluminum blades can flex, helping prevent damage to your engine.
Aluminum vs. Stainless Steel
Stainless Steel
Stainless steel MerCruiser props are ideal for large or heavy boats and boats running in saltwater. Although more expensive than aluminum, stainless steel MerCruiser props are more durable and will last longer. When running your boat at speeds over 50 mph, stainless MerCruiser props will perform better than aluminum.

Differences in Propeller Diameter.    
Diameter is the width of the circle that the MerCruiser prop would make when rotating.

Prop diameter does not affect the fit of the prop on a boat.

The diameter of your MerCruiser prop can vary by up to 1/2" with no discernable change in performance.

Caution: Before increasing the diameter of your MerCruiser prop, make sure there will be enough clearance between the blades and cavitation plate or anode on your engine.
