It supersedes part number 875827. A bellows is a perishable item that keeps water out of the drive, so its condition matters more than its mileage and it is normally renewed on a time basis rather than when it finally splits.

⚙️ Key Features

• Listed for 42 applications across MD, MB, AQ, BB, B and AQD series engines
• Supersedes 875827
• Marine Propulsion group

🔌 Function

Forms a flexible watertight seal across a joint that has to move, keeping seawater out of the drive while allowing the joint to articulate.

⚠️ Common Signs of Failure

• Cracks in the folds, visible when the bellows is flexed open by hand
• Rubber gone hard, chalky or perished at the clamp lines
• Water in the drive or in the bilge after a run
• Oil found in the water or a milky emulsion on the dipstick
• Clamps corroded, slack or cutting into the rubber

🛠️ Service Notes

• Renew the clamps with the bellows and set them to the specified positions — a reused clamp is the most common cause of a repeat leak
• Inspect the mating flanges for corrosion or scoring before fitting; a pitted flange will not seal against new rubber
