About this part
Multi-component transom bellows seal kit containing a U-joint bellows with clamp, exhaust bellows with clamp, shift cable bellows, gimbal bearing, water inlet hose, outdrive mounting gasket kit, and hose clamps. Designed for specified Volvo Penta SX and DP-S series sterndrives and most OMC Cobra sterndrives from 1986 onward when component references and exhaust configurations match.
The listed replacement numbers identify individual components within the kit and should not be treated as a single complete-kit OEM part number.
Match the application
This service kit fits the Volvo Penta SX and DP-S model designations listed below, as well as most 1986 and later OMC Cobra sterndrives subject to clutch and exhaust bellows verification. Identify the complete drive model including its suffix before ordering.

Year: 1986 and later
Fits most 1986 and later models when the included components match the drive configuration. Confirm the exact drive version, distinguish 1986–1993 dog-clutch arrangements from later cone-clutch arrangements, and verify the exhaust bellows reference number (this kit includes exhaust bellows 3850426 / 18-1074 rather than 914036 / 18-2764) instead of relying on model year alone.

Workshop sequence
General workshop guidance only; use the service procedure for your exact drive or engine configuration.
- Secure the vessel out of the water, disconnect battery power, and properly support the sterndrive assembly before removing the outdrive and old mounting gaskets.
- Remove the existing U-joint bellows, exhaust bellows, shift cable bellows, water inlet hose, and gimbal bearing, then clean and inspect all housing flanges and sealing surfaces.
- Compare each new component in the kit against the removed parts to verify matching profiles, hose connections, and bearing seating before installation.
- Seat the gimbal bearing and install the new bellows and water inlet hose without twists or folds, positioning clamps and applying any required adhesives strictly according to the service manual for your specific sterndrive model.
- Reinstall the sterndrive using the supplied outdrive mounting gasket kit and verify smooth shift cable movement and full trim/steering clearance across the operating range.
Questions from the workshop
Can I use this kit on Volvo Penta SX-A or DPS-A/B drives?
Do not assume that SX-A or DPS-A/B sterndrives use the same complete kit as the listed SX, SX-S, SX-C, SX-R, SX-M, DP-S, DP-S1, and DP-SM models. Always verify the full drive suffix and individual component part numbers for your unit.
What should I check before ordering for an OMC Cobra sterndrive?
Do not select by the name "Cobra" or model year alone. Distinguish between the 1986–1993 dog-clutch arrangement and later cone-clutch arrangements, confirm whether your drive uses an exhaust boot or bellows, and check whether your exhaust bellows matches 3850426 / 18-1074 (included in this kit) or the separate 914036 / 18-2764 catalogue version.
