The Aquadrive HDL42.680 Flanged Heavy Duty Line system is a marine propulsion anti-vibration system with integrated thrust bearing and flanged shaft connection. Designed for high-power installations, it isolates engine vibration while transferring propeller thrust directly to the vessel structure. Maximum torque 10,500 Nm, maximum shaft speed 1700 rpm, and maximum propeller thrust 40 kN.

Aquadrive HDL42.680 Flanged – Heavy Duty Line Antivibration System, Max Torque 10500 Nm
The Aquadrive HDL42.680 Flanged is part of the Aquadrive Heavy Duty Line (HDL), designed to eliminate the transfer of propeller thrust and vibrations from the propulsion shaft to the engine and vessel structure. By integrating a constant velocity (CV) joint with a thrust bearing system, the unit allows the engine to move freely on its flexible mounts while the thrust loads are absorbed by the Aquadrive housing mounted to the vessel’s structure.
This configuration improves onboard comfort, reduces vibration and noise levels, and simplifies engine alignment. The system uses the CV42 constant velocity joint and is engineered for applications with high torque and thrust loads, making it suitable for displacement and planing vessels.

Notes
- Rated power values are based on an optimum CV joint angle of 2°.
- If the CV joint operates at an angle greater than 2°, the maximum permitted power must be reduced.
- Typical power reduction is approximately 8–9% for each additional degree over 2°.
- Maximum allowable joint angle is approximately 5–8° depending on shaft rpm.
