Bruntons Propellers


  • Autoprop Propeller

    Autoprop’s unique design and superb build quality make it the first choice feathering propeller among cruising yachtsmen the world over, with drag reduction when sailing by at least 85%, and a unique ability to change pitch automatically to suit prevailing wind and sea conditions when motoring or motor sailing. Auto pitching, auto feathering, the same thrust in astern as ahead, less prop-walk in astern, a brand new version for hybrid and purely electrically driven vessels, and a recently developed ability to produce very efficient and economic propulsion for purely diesel powered displacement motor boats are more than reason enough.



    Bruntons SigmaDrive is a brand new 21st Century solution that is already an award winner and provides effective anti-noise and anti-vibration solutions of the highest order.

    What makes SigmaDrives different is their ability to resist propeller thrust when installed as a standalone coupling, directly from the shaft to the output flange on the engine’s transmission. It reduces and even eliminates vibrations that originate from an imperfect alignment between the propeller shaft and the engine, compensating for up to 3 degrees in all directions. This system can also be installed using thrust bearings so that the engine can be placed utilising the space available ergonomically.
