WHISPER Available From 18” - 48” Diameters, And For 1¼” - 3½” Shaft Diameters

FEATURES

The size of sailboats has been increasing steadily over the past few years. With the larger size comes the demand for bigger engines and higher speed under power, while keeping noise and vibration down to a minimum. To that affect, Max-Prop has designed a 5 blade propeller, combining all the necessary attributes. To address the horsepower gains, Max-Prop has added one more blade. This allows the transfer of power in the water in a more efficient way than the only other alternative - a larger diameter - while keeping noise to a minimum. In addition to the increased power, the extra blade provides a smoother run than a 4 blade propeller.

• Very efficient power • Outstanding reverse and stopping power • Ultra smooth operation • Very low drag • Simple bolt on installation • Externally adjustable pitch • Best suited for heavy displacement cruisers over 50 feet • Ideal for large yachts 70 to 150 feet • Available from 18" to 48" diameter • For shafts 1¼" to 3½"

SIMPLE INSTALLATION Due to the design of the Max-Prop Whisper, installation can be done in or out of the water with the simple bolt on installation.

LOW DRAG A 5 blade Max-Prop Whisper on a high angle shaft will have substantially less drag than a fixed 2 blade propeller and provides more power while motoring.

EASY PITCH ADJUSTABILITY

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.
