🔌 Function

Takes drive from the engine down through the hull and out to the propeller, combining the gearing, shafting and lower unit in one assembly.

⚠️ Common Signs of Failure

• Whine, growl or knock from the drive that changes with load
• Vibration through the hull under way
• Milky or emulsified oil showing water has entered the unit
• Metal particles in the drained oil
• Corrosion, growth or a damaged diaphragm found at the hull seal on lift-out

🛠️ Service Notes

• The 2.19:1 ratio alone does not identify the unit, so confirm the engine and part number before ordering
• Renew the shaft seals and the hull diaphragm sealing to the manual's schedule while the unit is out
• At 42.64 kg the lift needs planning and proper support
