For the ultimate in speed, maneuverability, efficiency and dependability, nothing matches Twin Disc Arneson Surface Drives. Their surface-piercing propeller design reduces underwater drag by 50% compared to conventional submerged propeller drive systems.
With the addition of Rolla Propellers to Twin Disc's extensive line of propulsion equipment, engine manufacturers, boat designers, builders, owners and operators now have one source for the greatest combined propulsion technology.
The SeaProp60 saildrive is a propulsion system for sailboats with engines rated up to 56 kW (75 hp) @ 3600 rpm. Sailboat manufacturers and operators alike benefit from this system's unique but proven design.
