The Aquadrive CVB10.10 Moduline B10 is a marine anti-vibration propulsion system combining a CV shaft, thrust bearing, and gearbox adapter. It isolates engine vibration and transfers propeller thrust to the vessel structure rather than the gearbox. Maximum torque 1300 Nm, maximum shaft speed 4000 rpm, and maximum continuous thrust 11 kN.

Aquadrive CVB10.10 – Moduline B10 Anti-Vibration CV Shaft System

The Aquadrive CVB10.10 Moduline B10 is an anti-vibration marine propulsion system designed to isolate the engine from propeller forces and vibration. By transferring propeller thrust through a dedicated thrust bearing mounted to the vessel foundation, the system reduces stress on the gearbox and improves onboard comfort.

The Aquadrive system combines a constant velocity (CV) shaft, a thrust bearing, and adapter connections to create a flexible drivetrain installation. The CV shaft includes two universal joints connected by a floating shaft, allowing axial and radial movement while maintaining smooth torque transmission.

Thanks to the Moduline modular design, installation length can be reduced significantly while maintaining strength and reliability. This modular construction also simplifies engine alignment and installation in confined engine compartments.

Main Components

Constant velocity shaft (CV joint assembly)
Thrust bearing with rubber suspension
Gearbox adapter flange
Shaft sleeve connection

Notes

Rated application examples are based on optimal operating conditions with approximately 2° joint angle for each CV joint. If the operating angle exceeds 2°, the maximum permitted power should be reduced by approximately 8–9% for each additional degree.

The maximum allowable joint angle typically ranges between 4° and 8°, depending on propeller shaft speed.
