🔌 Function

Carries the drive through the lower unit to the propeller shaft, its gears turning the vertical drive into shaft rotation in the chosen direction.

⚠️ Common Signs of Failure

• Whine or growl from the lower unit that changes with load
• Metallic debris or a bright glitter on the drain magnet
• Milky oil, showing water has been getting in
• Play or backlash felt at the propeller shaft
• Gear teeth found chipped, pitted or spalled on strip-down

🛠️ Service Notes

• This and 23699407 carry an identical published specification, so order by part number against the parts list rather than by hand and size
• Confirm the hand of the drive before ordering, as a left hand unit will not substitute for right hand 23699405
• Renew the shaft seals and the oil at the same time, since water ingress is what usually takes these gears out
