3594509 Drive-Joint Bellows Kit · Fits Volvo Penta DPH / DPR / DPI select, Replaces 3808898, CEF500537K

GHMarine drive-joint / U-joint bellows kit for select Volvo Penta DPH / DPR / DPI drives — kit OEM 3594509, bellow body 3808898. Aftermarket equivalent CEF500537K (same family as 3808898 / 3594509 — not a wrong-part exclude). BOM: 1 × drive-joint bellow 3808898 + hose clamp 853012 when supplied. A larger EPC clamp 22274888 may appear on some assemblies — confirm against your package; it is not claimed as a default sellable line on this page.

This seals the drive-joint cavity on DPH/DPR/DPI — it is not the exhaust bellow on the same platform (3588753 · GH 25B1093), and not an SX-A / DPS U-joint or exhaust kit.

Which kit is this?

It is the drive-joint (transmission / U-joint cavity) bellows kit for later Volvo Penta DPH / DPR / DPI drives that specify 3594509 or bellow body 3808898. Order as a kit — bellow plus clamp(s) — not as a bare boot alone.

It is not DPH/DPR/DPI exhaust 3588753 / CEF500538K (GH 25B1093), not SX-A / DPS exhaust 3888916 (GH 25B1094), not SX-A / DPS U-joint 22197130 / 23075752, not early SX/DP-S exhaust 3850426 (GH 17B1010), and not Cobra/SX U-joint 3854127 (GH 18B5002) or AQ 876294 (GH 17B1016).

Signs yours is due

• DPH / DPR / DPI drive-joint bellow is cracked, oil-soaked, or collapsing in the U-joint cavity — stamped 3808898 / 3594509 / CEF500537K when readable.
• You are on DPH-A/B/C/D/D1/E, DPR-A/B/C/D, or DPI-A and the EPC lists 3594509 / 3808898 for the drive-joint position (not the exhaust position).
• You almost ordered exhaust 3588753 or SX-A 3888916 because the bellow "looks similar" — stop and match drive-joint 3808898.
• Divert: same-platform exhaust → GH 25B1093. SX-A/DPS exhaust → GH 25B1094. Early SX 3850426 → GH 17B1010. Cobra/SX U-joint → GH 18B5002.

Will it fit my drive?

This kit is Compatible with select Volvo Penta DPH / DPR / DPI drives when EPC or the old part confirms 3594509 / 3808898 — including representative rows DPH-A/B/C/D/D1/E, DPR-A/B/C/D, and DPI-A when the official table / EPC hits. Drive model and OEM number decide fit — not SX-A / DPS, and not horsepower alone.

*Not for SX-A / DPS. Not interchangeable with same-platform exhaust 3588753. Final fit = 3594509 / 3808898 on the drive-joint EPC.

Install tips (DPH/DPR/DPI drive-joint)

DPH / DPR / DPI drive-joint cavity bellow service — not an exhaust channel job and not a MerCruiser three-bellow transom recipe. Cold engine; support the boat and drive; disconnect battery; follow the Volvo Penta procedure for drive-joint bellow replacement on your exact drive letter. Confirm 3594509 / 3808898 before install.

1. Confirm old bellow / EPC is 3594509 or 3808898 for the drive-joint cavity — not exhaust 3588753 and not SX-A 3888916.
2. Access the drive-joint cavity per the service manual; remove the old bellow and clamp(s).
3. Clean mating surfaces; install the new 3808898 bellow and 853012 clamp if supplied.
4. Tighten to the service-manual specification for that drive.
5. Run and inspect for leaks / grease weep at the drive-joint before returning the boat to service.
