The Aquadrive CVB15.10 Moduline B10 is a marine anti-vibration propulsion system combining a CV driveshaft, thrust bearing, and gearbox adapter flange. It isolates engine vibrations and transfers propeller thrust to the vessel structure instead of the gearbox. Maximum torque 1625 Nm, maximum shaft speed 4000 rpm, and maximum continuous thrust 11 kN.

Aquadrive CVB15.10 – Moduline B10 Anti-Vibration CV Shaft System
The Aquadrive CVB15.10 Moduline B10 is a marine anti-vibration driveline system designed to isolate the engine from propeller forces and vibrations. By transferring propeller thrust through a dedicated thrust bearing mounted on the vessel foundation, the system significantly reduces loads on the gearbox and improves onboard comfort.
The Aquadrive system combines a constant velocity (CV) shaft, a thrust bearing assembly, and a gearbox adapter flange. The CV shaft consists of two universal joints connected by a floating shaft, allowing axial and radial movement while maintaining smooth torque transmission even when the engine moves on its mounts.
Thanks to the Moduline modular construction, the system allows compact installations while simplifying engine alignment. This design improves installation flexibility and reduces vibration transfer to the hull structure.
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.
