Dramatically reducing vibration and noise
The Aquadrive® Antivibration System will help you and your crew enjoy the peace and quiet of boating. By isolating the engine from the rest of your boat, noise and vibration are greatly reduced. Most installations result in a 50% or more reduction in cabin or cockpit noise and vibration. Aquadrive will also help to keep your driveline in good condition by minimising wear and tear on the transmission and cutlass bearings. The propeller shaft is aligned to an Aquadrive thrust bearing, which absorbs the propeller thrust.
A Constant Velocity (CV) shaft transmits engine power to the thrust bearing and propeller shaft. The CV shaft automatically adjusts to changes in the alignment between engine and thrust bearing and allows engine movements in every direction. Unlike standard installations, periodic realignment will not be required. The use of softer engine mounts, which isolate engine vibration from the hull, completes the system.
Aquadrive® Antivibration System creates the necessary conditions for a smooth running, quiet boat.

A – The soft engine mounts isolate the engine from the hull.
B – The constant velocity driveshaft absorbs engine vibrations and eliminates the need for accurate alignment.
C – The thrust unit, fastened on a load bearing hull section, reduces stress on the transmission, on the engine
mounts and, in particular, on the engine bearings.
Engine mount
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.
Constant velocity shaft
The driveshaft 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 gearbox coupling kits allows problem free coupling to almost every marine gearbox transmission. Our CV shafts, as a standalone element, do provide a perfect and maintenance free solution for coupling of waterjets, IPS drives etc. to the remote engine side. Beside the above mentioned homokinetic advantages, the ball joints absorb vibrations through the driveshafts.
Thrust bearing
Aquadrive thrust bearing assemblies with rubber mounts attach to a cross brace in the hull. Robust 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.
Advantages
System with Aquadrive®
With the Aquadrive® anti-vibration system, the motor can be installed horizontally on soft motor feet. As a result, we achieve a noticeable reduction in vibrations and noise in the entire drive train. The Aquadrive® system can be retrofitted easily and even in tight engine compartments.
System without Aquadrive®
In a traditional powertrain installation, the drive shaft must always be precisely aligned with the engine – this requires regular maintenance. Rigid motor feet transmit high vibrations even with ideal alignment, which significantly increases the wear and tear on all components of the drive train.
