Flexible mechanical coupling

for boatsanti-vibration

- Aquadrive systems reduce noise by transferring the load of the propeller to the hull so that the engine can sit on soft vibration-absorbing mounts. In traditional engine installations, the engine must be very precisely aligned to the propeller shaft. The thrust of the propeller has to be absorbed by the engine and its mounts. These restrictions demand very stiff mounts that transmit high levels of vibration to the hull. Vibration becomes noise. The Aquadrive anti-vibration system eliminates the need for stiff, hard mounts and for careful engine alignment to the propeller shaft. Instead, the propeller shaft is aligned to an Aquadrive thrust bearing that is attached directly to a structural member of the hull. The thrust bearing absorbs the entire propeller thrust and stabilizes alignment. Constant velocity (CV) joint shafts transmit engine power to the thrust - bearing and propeller shaft while allowing the engine to move in any direction. Super-soft Aquadrive engine mounts isolate nearly all vibration from the hull. Engine Mounts Aquadrive's steel-hooded mounts are much softer than almost anything else manufactured, and are fully captive to keep the engine in place even if the vessel turns over. Pre-machined gearbox coupling kits allow trouble-free coupling to almost any marine gearbox transmission. All exposed fasteners are made of high-grade stainless steel. Constant velocity (CV) joints allow the shaft to connect the engine and the main propeller shaft at an angle. The rolling action of the balls within in the CV joints absorbs all axial and radial loads Aquadrive offers a variety of systems designed for propeller shaft driven boats from 5 to 1500 horsepower.
