📋 Kit Contents

• Complete assembled reversing gear - Volvo Penta 22775461
• 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
