  • 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.

Outstanding Power

Max-Prop Easy 4 blade has very low drag

Low Drag

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.
