Ability to adjust submergence to match horsepower output permits conversion of more thrust as appropriately needed. Propellers ventilate to the surface rather than cavitate under the hull reducing noise and destructive hull and prop erosion. Accessable propeller servicing. Steerage by the positive thrust of the propeller and not by the propellor thrust to the rudder. For all it's sophisticated performance, it is a less mechanically complex and fragile design than other propulsion systems.
All models are available in maganese bronze or aluminum.
No limitations to shaft angle, blade top clearance, draft to restrict selection of optimum diameter propeller. Adabtable to a wide range of engine applications, whether gas, diesel, or turbine. The Bar Assembly - mechanical or hydraulic. Required for multiple installations. Couplings - Federal, Morse, etc.
