This is a genuine Volvo Penta OEM pivot housing mounting gasket used at the mating surface between the drive-side pivot housing and the transom assembly on select Volvo Penta sterndrive models. It seals the drive-to-transom interface and should be replaced any time the drive or pivot housing connection is opened for service.

Specifications

• System: Sterndrive / Transom Assembly
• Type: Flat mounting gasket
• Application point: Pivot housing to transom shield mating surface
• Exact dimensions not published in current catalog. Confirm against your specific drive model, serial number, and parts diagram before ordering.

Compatible Applications

Fitment must be confirmed by drive model, serial number, and the correct Volvo Penta parts diagram. Commonly referenced applications include:

• SX-A, SX-B, SX-D (where specified by parts diagram)
• DPS-A, DPS-B, DPS-B1, DPS-D, DPS-D1 (where specified)
• FWD-B1, FWD-B2, FWD-D1, FWD-D2 (where specified)
• DPH / DP-H (where specified)
• DPR (where specified)

Serial Number Notice: Volvo Penta uses different gaskets, seals, and mounting hardware across SX, DPS, FWD, DPH, and DPR drive families. Drive family alone is not sufficient to confirm fitment — always verify by drive model, serial number, and the exact parts diagram position before ordering.

Alternate & Cross-Reference Part Numbers

• 3889788 — Volvo Penta OEM (this part, active number)
• 3883572 — Superseded Volvo Penta reference; verify by serial number and diagram before substituting

When to Replace

Replace this gasket any time the pivot housing or drive mating surface is separated during service. The gasket should not be reused — it compresses under torque and a disturbed gasket may not reseal reliably. Also replace if the existing gasket is compressed, torn, swollen, hardened, or leaking.

Installation Notes

• Clean both mating surfaces thoroughly before installing the new gasket — remove all old gasket material, salt buildup, corrosion residue, and debris without gouging the sealing faces
• Inspect the pivot housing, transom shield, bolt holes, bellows area, and surrounding hardware for damage before reassembly
• Do not reuse the old gasket
• Tighten mounting hardware to the Volvo Penta service manual specification for the specific drive and transom assembly

Service Interval

Replace whenever the pivot housing or drive connection is opened — during drive removal, bellows service, gimbal service, pivot housing inspection, or transom shield service. This gasket is a one-time-use sealing component and should be included in any sterndrive service kit for these drive families.

Technical FAQ

Can I reuse the old gasket if it looks undamaged?
No. This is a compression gasket that deforms under torque. Once disturbed, it may not reseal reliably. Always install a new gasket when the joint is opened.

Does this gasket fit all SX drives?
It covers a range of SX, DPS, FWD, DPH, and DPR applications, but fitment is not universal across all variants. Always confirm by drive model, serial number, and the parts diagram for your specific drive.

Is this the same as 3883572?
Yes — 3883572 is the superseded part number. 3889788 is the current active Volvo Penta part number for this application. Verify the supersession against your specific drive serial number before ordering.

Parts Desk Insights

This is one of the most cost-effective parts in a sterndrive service — it costs a fraction of the labour involved in pulling and reinstalling a Volvo Penta drive. We see repeat service calls where a drive was reinstalled without replacing this gasket, and the result is a slow water intrusion at the transom connection that’s easy to miss until it causes real damage. If the drive is already off for bellows, gimbal, or pivot housing work, there’s no good reason not to replace this gasket at the same time. Keep one on hand if you do your own sterndrive service.
