The Aquadrive CVB05.10 Moduline B10 is a marine anti-vibration propulsion system combining a CV shaft, thrust bearing, and gearbox adapter. It isolates engine vibrations, transfers propeller thrust to the vessel structure instead of the gearbox, and simplifies engine alignment. Maximum torque 1034 Nm, maximum shaft speed 4000 rpm, and maximum continuous thrust 11 kN.

Aquadrive CVB05.10 – Moduline B10 Anti-Vibration CV Shaft System
The Aquadrive CVB05.10 Moduline B10 is an anti-vibration propulsion system designed for marine installations. It separates the engine from propeller forces and vibration, improving drivetrain reliability and onboard comfort.
In traditional propulsion systems, propeller thrust is transmitted directly to the gearbox and engine foundation. The Aquadrive system instead transfers the thrust through a dedicated thrust bearing mounted on the vessel foundation. This reduces stress on the gearbox while allowing the engine to move freely on its mounts.
The system includes a constant velocity (CV) shaft, a thrust bearing, and the necessary adapter connections. The CV shaft contains two universal joints connected by a floating shaft that allows axial and radial movement while maintaining smooth power transmission.
The Aquadrive Moduline design is modular, allowing the overall installation length to be reduced to approximately 70% and weight to around 75% compared with traditional propulsion installations. This makes installation easier and simplifies engine alignment.
Main Components
- Constant velocity shaft (CV joint assembly)

Propeller Shaft Options
The B10 standard version supports the following propeller shaft diameters:
- 3/4"
- 20 mm
- 22 mm
- 7/8"
- 25 mm
- 1"
- 1 1/8"
- 30 mm

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.
