## 🔌 Function

Takes the engine's output through the transom and turns it down through the drive gears to the propeller shaft, steering and trimming the thrust as the helm demands.

## ⚠️ Common Signs of Failure

-   Whining or growling from the drive that follows boat speed
-   Vibration through the hull under load
-   Gear oil milky, or the level dropping between services
-   Metal glitter on the magnetic plug or in the drained oil
-   Pitted gear teeth, worn bearings or a leaking bellows found on strip-down

## 🛠️ Service Notes

-   Confirm the ratio against the boat's propeller and engine before ordering - 1.69:1 drive 23493456 and 1.85:1 drive 23493457 are the alternatives in this group
-   At over 120 kg this is a lifting job needing proper equipment and planning
-   Renew the transom seals and bellows and set the alignment on installation, then check the gear oil and for leaks after the first run
