3854127 + 3852352 + 3850426 U-Joint, 1-Inch Inlet & Exhaust 3-Piece Set · Fits OMC / Volvo SX cone-clutch select, Replaces 18-2765, 18-1074

GHMarine 3-piece transom service set for select OMC Cobra / Volvo Penta SX cone-clutch assemblies — BOM 3854127 × 1 (U-joint bellows) + 3852352 × 1 (1-inch water inlet hose) + 3850426 × 1 (cone-clutch exhaust bellows). U-joint crosses 18-2765, 89200, 9-72707; inlet crosses 0769440 / 769440 / 911830; exhaust crosses 18-1074, 89190, 9-72711. This is a GHMarine internal combination — not a factory OEM parent kit number.

Order this set only when all three OEM numbers hit the same drive / transom EPC. Need bellows only (no inlet hose) → GH 17B3006. Need one part only → GH 18B5002 (U-joint), GH 18H1005 (1-inch inlet), or GH 17B1010 (exhaust 3850426).

Which set is this?

It is three service parts sold together: one U-joint / driveshaft bellow, one 1-inch molded water inlet hose, and one cone-clutch exhaust bellow. Count three distinct parts in the carton — this is not a "dual bellow" pack that omits the inlet hose.

It is not a dual-bellow pack without the inlet (GH 17B3006), not U-joint-only (GH 18B5002), not inlet-hose-only (GH 18H1005), not exhaust-only (GH 17B1010), not AQ 875826 / 875822 / 876294 / 876631 families, and not a MerCruiser three-bellow kit.

Signs you need the full three-piece set

• U-joint bellow (3854127 / 18-2765), 1-inch inlet hose (3852352 / 0769440), and exhaust bellow (3850426 / 18-1074) are all due on the same Cobra/SX cone-clutch haul-out.
• EPC lists all three numbers on the same drive / transom shield — buy one 3-piece set instead of three separate singles.
• You almost ordered a "dual bellow" pack and forgot the 1-inch inlet hose still needs replacement — stop and use this page.
• Divert: no inlet needed → GH 17B3006. One part only → 18B5002 / 18H1005 / 17B1010. AQ platform → not this page.

Will it fit my drive?

This 3-piece set is Compatible with select OMC Cobra / Volvo Penta SX cone-clutch / SX–DP-S assemblies only when 3854127, 3852352, and 3850426 all appear on the same EPC. Do not order from horsepower alone or from a year union of the three single-part catalogs.

*Intersection fitment only. If any one OEM is missing from your EPC, buy the matching single page(s) instead of this set. Not for AQ / 280 families (875826 / 875822 / 876294 / 876631).

What ships in the box

• 1 × U-joint / driveshaft bellows (3854127)
• 1 × 1-inch water inlet hose (3852352)
• 1 × Cone-clutch exhaust bellows (3850426)
• Clamps / hardware when supplied — confirm against package

Gallery note: some photos may show a single bellow for shape reference. The sold BOM is three parts — U-joint bellow + 1-inch inlet hose + exhaust bellow. Count all three before install; do not treat a dual-bellow photo as this carton.

Often ordered with related SKUs

• Bellows only (no inlet) → GH 17B3006
• U-joint only → GH 18B5002
• 1-inch inlet only → GH 18H1005
• Exhaust only → GH 17B1010

Install tips for the three parts

Cone-clutch / SX transom service covering U-joint bellow, exhaust bellow, and 1-inch inlet hose. Cold engine; support the boat and drive; disconnect battery; follow the OMC / Volvo Penta procedures for each part. Bellow jobs usually require removing the sterndrive and using the adhesive / expander method in the manual. Confirm the inlet is still 1-inch (not 1-1/4-inch) before installing 3852352.

1. Confirm EPC lists all three: 3854127, 3852352 (1-inch), and 3850426 on the same assembly — if any is missing, buy singles instead.
2. Lay out all three parts; identify U-joint bellow vs exhaust bellow vs molded inlet hose.
3. Replace bellows per the drive-removal / adhesive procedure; replace the inlet hose on the 1-inch circuit with correct clamp lands.
4. Reassemble; check seating and leaks at the U-joint, exhaust, and inlet positions before returning the boat to service.

FAQ

How many parts are in this set?

Three: 3854127 U-joint bellow, 3852352 1-inch inlet hose, and 3850426 exhaust bellow. Not a dual-bellow pack.

Is this the same as 17B3006?

No. 17B3006 is U-joint + exhaust only (no 3852352 inlet). This page adds the 1-inch water inlet hose.

Is this a factory OEM kit number?

No. 19B3001 is a GHMarine internal three-part combination. There is no single factory parent kit OEM claimed here.

What if only two of the three OEMs match?

Do not buy this set. Order the matching singles: GH 18B5002, GH 18H1005, and/or GH 17B1010 — or GH 17B3006 if you need both bellows without the hose.

Will AQ 200–290 parts fit?

No. AQ uses 876294 / 876631 / 875822 families. This page is Cobra/SX cone-clutch with the three OEMs above.

Do photos show all three parts?

Some gallery shots are single-part shape references. The carton quantity is three — count U-joint + inlet + exhaust.

Please note

Aftermarket replacement by GHMarine. Not affiliated with engine manufacturers named above. "Compatible with", "Replaces", and cross-ref numbers identify the 3854127 / 3852352 / 3850426 families — always confirm all three OEMs on the same EPC, 1-inch inlet size, and carton contents before ordering.
