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 horse power 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.
5 Blade Whisper
Available for shafts 1-1/4" to 3-1/2" or metric equivalent.
Please allow 3-5 days of handling before we can ship your Max-Prop propeller. This is to allow any time for boring and assembly.
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 disassembled to change the pitch.
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.
Just like other Max-Prop propellers, the Easy 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.
The Max-Prop provides 80% more power than a comparable fixed blade propeller. The Max-Prop utilizes the same leading edge in forward as it does in reverse giving the propeller the same thrust in both directions dramatically improving control and power in reverse.
