5 blade Max-Prop Whisper

Whisper

The Max-Prop Whisper is available from 18" to 50" diameters and are for 1" to 4" diameter shafts.

The Max-Prop Whisper uses five blades to provide ultra quiet operation and impressive thrust. The resulting powering performance is especially noticeable when powering against heavy wind and seas. The five blade design also provides for a substantial noise and vibration reduction in all conditions.

The Whisper is based on the Max-Prop Easy design, so it ships fully assembled, making installation and pitch changes simple and fast. The pitch is adjustable by 2 degree increments, providing the ability to fine tune the loading of the engine. Moreover, pitch adjustment can be done in the water as the propeller does not need to be disassembled to change the pitch.

The Whisper is designed for large vessels with heavy displacement, which can benefit from the extra thrust and quiet performance of a five blade propeller.

Extremely Low Drag

Under sail the Max-Prop Whisper will increase sailing speed by about 15%, the largest difference being noticed when sailing in light air. When sailing with a fixed propeller, the vessel has to overcome the fixed blade drag. Installing a Max-Prop Whisper maximizes sailing performance.

Adjustable Pitch

If your engine achieves either too much or to little RPM at max throttle, adjust the pitch to a higher or lower setting to attain the correct RPM. Pitch adjustment can be done in the water as the propeller does not need to be disassembled to change the pitch.

Smooth Operation

A five blade propeller will offer the smoothest possible run under power, quieting down your drivetrain.

Outstanding Reverse

The Max-Prop Whisper provides 80% more power than a comparable fixed blade propeller. The Classic utilizes the same leading edge in forward as it does in reverse giving the propeller the same efficiency in both directions dramatically improving control and power in reverse.
