4-Blade Feathering Propeller
Top Quality Features
Materials
J Props components are made from a variety of stainless steel and aluminium bronze.
Each alloy is designed to suit the specific properties of the application.
For example, the pitch gear, blades, housing and tail cone are all made from different alloys resulting in less wear between the parts.
The combination of stainless steel and aluminium-bronze components also enhance lubrication and minimize corrosion.
Automatic Blade Rotation
The most important feature of all JPROP propellers is the automatic blade rotation, which during engine operation quickly changes the pitch from forward to reverse.
Due to this feature, the same power is achieved in both operations and even a better performance in reverse, which is really important in particular on a classic or vintage boat.
Moreover, while cruising, the propeller has free rotation to easily obtain the feathered position for minimum drag under sail.
