⚙️ Key Features

• 0.528 kg
• Marine Propulsion group
• No engine fitment listed, so confirm the drive model before ordering

🔌 Function

Seals and flexes the exhaust path between engine and drive, allowing the drive to trim and steer without breaking the exhaust joint or letting water in.

⚠️ Common Signs of Failure

• Exhaust smell or fumes in the engine space or bilge
• Water entering the bilge through the transom area
• Bellows cracked, split, perished or chafed, often in the folds
• Clamps corroded, loose or the bellows pulled off its seat
• Rumbling or hollow exhaust note that changes as the drive is trimmed

🛠️ Service Notes

• Exhaust and drive bellows are a life-limited safety item because a failure lets water into the boat, so replace on condition and on age
• Inspect the drive bellows and the shift and steering components while the drive is off, since they all come apart together
• Fit new clamps, seat the bellows fully on both flanges and check the drive trims through its full range without pinching
