A five blade propeller will offer the smoothest possible run under power, quieting down your drivetrain.
In forward the Max-Prop will offer 96% of the efficiency of a fixed blade propeller of the same diameter and pitch. The 4% loss in power can usually be eliminated by precisely matching the pitch of the Max-Prop to fit the boat engine combination. The three blade has a major advantage when going against heavy winds and seas, it will maintain the boat speed up to 30% better than the two blade.
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.
Just like a other Max-Prop propellers, the Whisper feathers to a low drag position while sailing. Under sail the Max-Prop 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 maximizes sailing performance.
If your engine achieves either too much or too 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 fully disassembled to change the pitch.
