Volvo Penta Exhaust Bellows Kit 3888916 | SX-A DPS FWD Sterndrive

Volvo Penta Exhaust Bellows Kit — Part No. 3888916

This is the OEM exhaust bellows kit for selected Volvo Penta SX, DPS, and FWD sterndrive families. The kit includes the exhaust bellows and clamps required for the exhaust connection in the gimbal ring and pivot housing assembly. It is identified at diagram reference position 22 in the Volvo Penta gimbal ring and pivot housing schematic. Fitment follows the sterndrive and transom assembly, not the engine displacement — always confirm by drive model and serial number.

Compatible Applications

Confirmed sterndrive applications:

• SX-A
• SX-D
• DPS-A
• DPS-B
• DPS-D
• FWD-B1 / FWD-B2
• FWD-D1 / FWD-D2

Confirm by exact drive model and serial number before ordering. Similar exhaust bellows kits can look alike but cover different drive housings.

Serial Number & Drive Fitment Notice

Exhaust bellows fitment is determined by the sterndrive and transom assembly configuration, not engine size. Always confirm part number 3888916 against the exact drive serial number and the correct Volvo Penta gimbal ring / pivot housing breakdown before ordering — especially on applications where similar bellows kits cover different housing generations.

When to Replace

Replace the exhaust bellows kit when:

• The bellows shows cracking, splitting, or hardening
• Damage or distortion is visible around the clamp areas
• Water or exhaust leakage is present at the bellows connection
• Age-related deterioration is evident on inspection
• Adjacent sterndrive or transom service has the exhaust connection already open and the bellows shows any wear

Exhaust bellows are a maintenance item. Replacing them proactively during related service is far more cost-effective than reopening the drive after a failure.

Installation Notes

Confirm the part number and drive diagram position before installation. Inspect the related bellows seating surfaces, clamp contact areas, and pivot housing for corrosion or damage. Replace the clamps included in this kit rather than reusing old hardware. Check adjacent components at the same time:

• Volvo Penta Gimbal Bearing 3888555 — inspect for roughness or play
• Volvo Penta Pivot Housing Mounting Gasket 3889788 — replace if disturbed

Parts Desk Insights

Best use: Order 3888916 when servicing the exhaust bellows connection on an SX-A, DPS, or FWD sterndrive where the Volvo Penta gimbal ring / pivot housing diagram calls out this kit at position 22. It is the correct OEM replacement that includes both the bellows and clamps for a complete service.

Common customer issue: Exhaust bellows are easy to mis-order by appearance because several Volvo Penta kits look similar but fit different drive housing generations. Always match by drive family and serial number rather than by bellows shape or size. It’s also worth inspecting and replacing the gimbal bearing and pivot housing gasket during the same service — the incremental cost is low compared to reopening the drive later.
