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.

Adapters
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.

CV-shaft
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.

Thrust bearing
The thrust bearing is mounted directly into a structural member in the hull allowing the propeller to push the boat and not the engine.

Aquadrive offers a variety of systems designed for propeller shaft driven boats from 5 to 1500 horsepower.

Aquadrive Systems for Other Propulsion Applications

Stern Drive
Some boats perform better and have improved layouts by REMOTE MOUNTING the engine from the stern drives. The Aquadrive CVT systems offer unique engineering, which allows variable angles at end. Compared to U-joint driveshafts, CV axles absorb vibration instead of increasing it.

Examples:

Remote V-Drive
Only CV joints can permit uneven or compound angles between the engine and REMOTE MOUNTED V-DRIVE gearbox. Other driveshafts require identical angles on each joint and their angles can not change. Aquadrive's CV joint technology allows movements and misalignment in every direction. Unlike U joints, there is no driveshaft vibration and increased design flexibility.

Waterjet
Aquadrive CV tubular driveshafts offer the best technology to connect engines to waterjets. The unique misalignment and vibration absorbing capabilities of Aquadrive CV joints provide design improvements. Vibration and noise are reduced, and machinery arrangements and propulsion system reliability are improved
