⚙️ Key Features

• Gear housing from the Marine Propulsion group
• 20.38 kg
• Supersedes 22846275 and covers its 11 applications across D series engines and DPI drives

🔌 Function

Carries the drive's gears, shafts and bearings, holding them in the correct relationship to each other and retaining the oil around them.

⚠️ Common Signs of Failure

• Drive oil loss with no obvious seal leak
• Milky drive oil showing water has been getting in
• Cracks around the bearing bores or the mounting face
• Bearing bores worn oval or fretted on strip-down
• Corrosion damage to the outside, particularly around the fixings

🛠️ Service Notes

• A housing is supplied bare - plan on new bearings, seals and shims to build it up
• Establish why the old housing failed; a grounding or a seized bearing damages more than the case alone
• At over 20 kg it needs support during handling
