## 📋 Kit Contents

-   Complete assembled reversing gear - Volvo Penta 22775503
-   Internal shafts, bearings, clutch packs, oil pump and control valve are factory assembled and are not supplied as separate items within the kit listing
-   Engine adapter, flexible coupling, oil cooler, propeller flange and control hardware are separate unless specifically included in the installation package

## 🔌 Function

The transmission reduces engine speed to the propeller shaft, provides forward and reverse engagement and transfers engine torque through hydraulically operated clutch packs.

## ⚠️ Common Signs of Failure

-   Delayed or harsh forward / reverse engagement
-   Gear oil is dark, contaminated or contains metal
-   Hydraulic pressure is low or unstable
-   Bearing, gear or clutch noise develops

## 🛠️ Service Notes

-   Work clean and dry — the reversing gear circulates its oil through everything in this kit, so grit introduced during assembly ends up in the gears and bearings
-   Fit the new seals, gaskets and locking parts supplied with the kit and discard the corresponding old ones, including any that still look serviceable
-   Inspect the flexible coupling, shift linkage, control cable and mountings while the gear is accessible; worn ones will undo the benefit of the new parts
-   Refill with the oil grade and quantity specified for your reversing gear, then recheck the level after a short run once the new parts have taken up oil
-   Confirm the gear engages fully and cleanly in both ahead and astern and returns properly to neutral before the boat is used
