The Aquadrive CVB05.05 Moduline B05 is a compact anti-vibration propulsion system consisting of a CV shaft, thrust bearing, and adapter components. It isolates engine vibrations, transfers propeller thrust to the hull foundation instead of the gearbox, and simplifies engine alignment. Maximum torque 610 Nm, maximum shaft speed 4000 rpm, and maximum continuous thrust 6 kN.

Aquadrive CVB05.05 – Moduline B05 Anti-Vibration CV Shaft System
The Aquadrive CVB05.05 Moduline B05 is a compact anti-vibration driveline system designed for marine propulsion installations. It separates the engine from propeller forces and vibrations, improving drivetrain reliability and onboard comfort.
Traditional propulsion systems transmit propeller thrust directly to the gearbox and engine foundation. The Aquadrive system instead transfers the thrust to a dedicated thrust bearing mounted on the vessel foundation. This reduces load on the gearbox while allowing the engine to move freely on its mounts.
The system consists of a constant velocity (CV) shaft, thrust bearing, and gearbox adapter flange. The CV shaft contains two universal joints connected by a floating shaft, allowing both axial and radial movement while maintaining smooth power transmission.
The Aquadrive Moduline design is modular, reducing overall installation length to approximately 70% and weight to about 75% compared with traditional systems. This simplifies installation and makes engine alignment significantly easier.
Main Components
- Constant velocity shaft (CV joint assembly)
- Thrust bearing with rubber suspension
- Gearbox adapter flange
- Shaft sleeve connection
Technical Specifications
Model CVB05.05 System Type Aquadrive Moduline B05 Maximum Static Torque (ØA = 20 mm) 610 Nm / 450 lbft Maximum Propeller Shaft Speed 4000 rpm Maximum Continuous Propeller Thrust 6 kN / 1350 lbf Typical Power Range 5 – 235 hp (depending on configuration)
Typical Applications
Vessel Type Rated Power Crankshaft Speed Gearbox Ratio Sailing Boat 25 kW (34 hp) 3800 rpm 2.6 : 1 Displacement Motorboat 20 kW (27 hp) 2600 rpm 3.0 : 1
Propeller Shaft Options
The B05 standard version supports the following propeller shaft diameters:
- 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.
