Engine mounts

Aquadrive’s proven engine mounts are softer than almost any other and should be used to take full advantage of the system. These mounts are steel hooded to prevent diesel damage and fully captive so that the engine cannot leave its frame even if the vessel is turned over.

CV shaft

The drive shaft of variable length includes two true plunging Constant Velocity joints that work independently at any angle. This eliminates the need for accurate engine alignment, either during initial installation or subsequent use. The rolling action of the balls within the CV joints absorb all axial and radial loads, permitting the use of very soft engine mounts as well as reducing wear in connected bearings. A range of pre-machined adapter kits allows coupling to almost any marine gearbox.

Thrust bearing

Aquadrive thrust bearing with rubber mounts attach to a cross brace in the hull. Massive bearings transfer the thrust directly to the hull and not the engine. In addition, the propeller shaft is much better supported, leading to smoother running and less wear on the stern seal.

With Aquadrive

With Aquadrive the engine can be installed in a horizontal position using soft and efficient mounts. Apart from easy installation and permanent alignment, this also leads to better space utillisation while dramatically reducing vibration and noise.

Without Aquadrive

In traditional installations, the alignment of the propeller shaft to the engine has to be precise and subject to periodical maintenance. Stiff mounts transmit high level's of vibration to the hull, even when perfectly aligned.

Aquaderive advantage

A. Soft engine mounts isolate engine from hull

 

B. Constant Velocity (CV) drive shaft absorbs engine vibration and eliminates need for accurate alignment.

 

C. Thrust unit on load bearing hull section reduces stress on transmission and engine mounts. Prop pushes boat, not engine.
