This information is critical to determining the correct propeller for your application:
1.3 Blades
3- blade propeller usually offer s top speed performance.
2. Diameter:
Diameter is the distance across a circle encompassing all of the propeller blades.
3. Pitch:
Pitch is the theoretical distance a propeller will move through the water of each revolution.
4. Right hand or left hand Rotation
In most cases, right hand propellers are used for single engine application and one left hand propellers are used for twin engine applications to achieve better steering control.
5. Cupped Blades:
This is a technique used to enhance the performance of propellers under certain conditions. A cupped propeller will exhibit very high efficiency at high speeds as well as minimize cavitation under heavy loads.
6. Rake:
Rake is special design feature. Positive rake benefits from normal bow lift to permit the use of a larger diameter propeller, while negative rake can provide extra blade strength for use in very high speed applications.

Main Advantages
1. smaller diameter of the propeller hub can reduce the total propeller weight, increase the ship speed, energy-efficient and also lower the manufacture cost of the propeller
2. the hub diameter ratio for the blade against the propeller hub is lower which make sure the best propulsion
3. the high quality material makes sure longer serving life for the propeller
