What's Inside an Aquadrive?

The Aquadrive has four main components. The gearbox adaptor is ready made to couple our drive to your gearbox. Behind this comes the Aquadrive special drive shaft, with a tough constant velocity joint at each end. Then the thrust bearing, engineered to take forward and reverse thrust, and rubber mounted to reduce noise. Finally the shaft coupling, produced for a wide variety of shaft diameters.

Gearbox adaptors are produced for almost every gearbox on the market today. They are supplied with all the correct nuts, bolts and washers.

The thrust bearing is incredibly tough and built with races which can be replaced even after many years running. Sealed ball bearing races require zero maintenance on smaller Aquadrives. Taper roller units are built into the larger systems.

The Aquadrive special drive shaft will take an angle of up to 8 degrees at each end, and then take even more movement due to vibration. It will even take fore and aft movement – it is easy to forget that an engines vibrates fore and aft as much as it does up and down!

Specially engineered shaft clamps, with bolts safely hidden inside the thrust bearing, are built into the new Moduline series of Aquadrives to reduce length and weight.
