3854127 U-Joint Drive Bellows · Fits OMC Cobra clutch-dog select 1986–1993, Replaces 18-2765, 89200, 987467

GHMarine U-joint / driveshaft bellows for select OMC Cobra clutch-dog drives — OEM 3854127 (single bellow). Legacy / supersession numbers include 987467, 983973, 3841481 (and 22197130 only when your EPC chain lists it). Cross-refs 18-2765, 89200, 9-72707, 85127P.

This page is the canonical single-bellow listing for the 3854127 / 987467 U-joint family. Internal CSKUs 18B1002, 17B1009, and 24BL043 map to the same physical bellow — do not buy a second page for the same part. It is not AQ U-joint 876294 (GH 17B1016), not shift bellow 911826, not exhaust bellow 3850426 / 914036, and not a complete gimbal-bearing / multi-boot kit.

Which bellow is this?

It is the rubber U-joint / driveshaft bellow that seals the clutch-dog drive joint on the listed OMC Cobra packages (and on select Volvo SX / DP-S only when EPC confirms 3854127). Confirm the old bellow or EPC shows 3854127 / 987467 / 983973 before you order.

It is not Volvo AQ U-joint 876294 (GH 17B1016 / combo 18B2001), not shift bellow 911826, not cone-clutch exhaust bellow 3850426 (GH 17B1010), not drive bellow 914036, not MerCruiser U-joint 816431A1, and not bellow adhesive 18-9031-1 (glue is not a bellow).

Signs yours is due

• OMC Cobra clutch-dog U-joint boot is cracked, split, oil-soaked, or collapsing — stamped 3854127 / 987467 / 18-2765 / 89200 when readable.
• Water or gear-lube evidence around the driveshaft bellow (not an engine-bay exhaust hose and not the shift bellow).
• Your chart shows 987467 or 983973 but the physical bellow is the same U-joint family as 3854127 — stay on this page; do not open a second storefront SKU for the same boot.
• Divert: AQ 876294 → GH 17B1016. Shift 911826 → that family. Exhaust 3850426 → GH 17B1010. Complete bearing kit → not this page.

Will it fit my drive?

This bellow is Compatible with select OMC Cobra clutch-dog sterndrives about 1986–1993 that specify 3854127 / 987467 / 983973. It is also Compatible with select Volvo Penta SX / DP-S drives only when EPC or the old bellow confirms 3854127 — do not order from a vague "1994–current" SX tag alone.

*Primary dual-table band for Cobra. Volvo SX/DP-S rows require EPC proof — not a series-name free pass. Not for Volvo AQ 876294 applications.

OEM & swap numbers

Install tips (drive bellow)

Drive / U-joint bellow work. Cold engine; support the boat and drive; disconnect battery; follow the OMC / Volvo Penta service procedure for Cobra clutch-dog or SX/DP-S bellow replacement. This job usually requires removing the sterndrive and using the bellow adhesive / expander method in the manual — do not treat it like a short engine-bay exhaust hose. Adhesive (e.g. 18-9031-1) is sold separately when needed.

1. Confirm old bellow / EPC is 3854127 / 987467 / 983973 — not AQ 876294 and not shift 911826.
2. Remove the drive per the service manual; support the bellow area.
3. Cut / remove the old bellow; clean mating surfaces; prepare adhesive only as the manual specifies.
4. Install the new bellow and clamps (if supplied) in the correct orientation; expand / seat per the procedure for that drive.
5. Reinstall the drive; check alignment and bellow seating; run and inspect for leaks before returning the boat to service.
