Autoprop 3-Blade Propeller

Suitable for engines rated to 350HP.

The Autoprop is the only fully automatic self-pitching propeller available.

The Autoprop has the identical blade shape in forward or reverse, the leading edge in forward is the leading edge in reverse and therefore gives more control for backing or manoeuvring due to its superior reverse thrust and optimum pitch setting – resulting in virtually no ‘prop walk’ from the propeller.

When sailing, the Autoprop automatically feathers its blades to the angle of least resistance, creating a drag reduction of 85% when compared to a fixed propeller.

No pitch adjustment to make after installation and sea trials. Motor-sailing is vastly improved with greater thrust at lower RPMs.
