Under sail
The MAX-PROP feathers to a low drag shape. Compared to a folding propeller, the extra wetted surface of the MAX-PROP blades is offset by the reduction of projected area: "A".

Available in 2 or 3 blades.

In Forward gear
The torque of the prop shaft acting on a "differential" type design will open the blades in unison to the pre-set pitch at any throttle setting. This will provide maximum  efficiency (96% of same sized fixed prop) and eliminate the vibration problems of a folding prop.

In Reverse
As in forward, the torque of the shaft will rotate the blades 180 degrees in less than 3/4 of a shaft rotation,  presenting the same leading edge and pitch in reverse.  This provides better directional control and 80%  greater power than a comparable fixed blade propeller.

The original two blade MAX-PROP was designed in the early 70's for the high tech racing boat. Since proving itself in the racing arena, the Two Blade Classic MAX-PROP has earned its way into the mainstream market as a leader of low drag propellers. While satisfying the racer with low drag, its efficiency under power in both forward and reverse is sure to please all. The Two Blade Classic's pitch can be adjusted to help achieve the maximum efficiency from the engine without having to purchase a new propeller.

With the increased popularity of the cruising vessel, MAX-PROP introduced its three blade classic model in the early 80's. This propeller will enhance a vessel's performance both under sail with less vibrations, better power in load conditions and under sail with reduced drag. With its unsurpassed powering ability in both forward and reverse, the three blade classic MAX-PROP has become a legend among the sailing community.

Installation Manual

Max-prop's newest addition to its product line is the V.P. model. The MAX-PROP V.P. offers the unique feature of external pitch adjustment using a breakthrough patented system. This system allows for a complete pitch adjustment by a diver, without any tool. Giving its owner the ability to easily fine tune

Installation Manual

The V.P. System

Pitch adjustment on the V.P. is achieved by tuning the external adjustment ring at the front of the prop hub.

With the worldwide acceptance and use of saildrive units, MAX-PROP developed both a two and three blade which adapt to the spline of the drive unit with no modification. The user will experience the same advantages as with a Classic MAX-PROP, low drag, superior forward propulsion and unsurpassed reverse power. The MAX-PROP is adaptable to the Volvo, Yanmar or Bukh saildrive units.
