  • Description

    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.
