The Aquadrive HDL48.690 Heavy Duty Line system is a high-capacity marine propulsion anti-vibration system with integrated thrust bearing and CV shaft designed for powerful propulsion installations. It transfers propeller thrust directly to the vessel structure while isolating engine vibration and protecting the gearbox from axial loads. Maximum torque 12,240 Nm, maximum shaft speed 1700 rpm, and maximum propeller thrust 40 kN.

Aquadrive HDL48.690 – Heavy Duty Line Anti-Vibration Thrust Bearing System, Max Torque 12240 Nm

The Aquadrive HDL48.690 is part of the Aquadrive Heavy Duty Line (HDL), designed to eliminate the transfer of propeller thrust and drivetrain vibrations from the propulsion shaft to the engine and vessel hull. The system integrates a thrust bearing housing with a constant velocity (CV) joint, allowing the engine to move freely on flexible mounts while all propeller thrust forces are absorbed by the Aquadrive unit mounted to the vessel structure.

This configuration significantly improves onboard comfort, reduces vibration and structural noise, and simplifies engine alignment during installation. The system is designed for higher power marine propulsion applications and uses the CV48 constant velocity joint, providing reliable operation under high torque and thrust loads.

Application Examples

Boat Type Rated Power Crankshaft RPM Gearbox Ratio

Displacement boat 410 kW (550 HP) 2100 rpm 3 : 1

Planing boat 670 kW (900 HP) 2800 rpm 2 : 1

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