Aquadrive 6040462A – CV21 Adapter Flange Ø120 mm for Yanmar KM4A-1 / KBW20-1 / KBW21 / KM4A Gearboxes
The Aquadrive 6040462A Adapter Flange is designed to connect Aquadrive propulsion systems to compatible marine gearboxes. It provides the mechanical interface between the gearbox output flange and the Aquadrive constant velocity drivetrain assembly.
This adapter flange is engineered for Aquadrive CV21 propulsion systems (CVB21.20) and is compatible with Yanmar KM4A-1, KBW20-1, KBW21 and KM4A marine gearboxes. Precision-machined mounting geometry ensures accurate alignment and reliable installation within marine propulsion systems.
Selecting the correct Aquadrive adapter flange is essential for proper system integration. It allows the thrust bearing and constant velocity shaft assembly to connect correctly with the gearbox output flange, helping maintain smooth torque transmission while reducing drivetrain vibration and misalignment loads.
