Recmar Sealing Ring | 3593663 | Volvo Penta Sterndrive | Replaces 851979 873108 23370796

The Recmar #3593663 is an aftermarket replacement sealing ring for Volvo Penta sterndrive and marine engine applications. Sealing rings in Volvo Penta drive systems provide static and dynamic seals at shaft interfaces, housing mating surfaces, and fluid passages — preventing oil, gear lube, and coolant from bypassing between cavities or leaking externally. Recmar is an established marine aftermarket parts manufacturer producing seals, gaskets, and mechanical components engineered to meet or exceed Volvo Penta OEM specifications. Replaces Volvo Penta 851979, 873108, 23370796, and 3582889.

Additional Information

When to Replace a Volvo Penta Sealing Ring:

Sealing rings in Volvo Penta sterndrive systems should be replaced any time the components they seal are disassembled for service — they are single-use components that compress or deform on initial installation to create their seal and cannot reliably re-seal after removal. Common service intervals that require sealing ring replacement:

• Gear lube change — any sealing ring at a drain or fill plug interface should be replaced each service interval; a reused sealing ring at a gear lube drain is a leading cause of slow gear lube leaks that go undetected until bearing damage occurs
• Drive removal and reinstallation — sealing rings at the drive-to-transom shield interface must be replaced whenever the drive is pulled for bellows service, gimbal bearing replacement, or u-joint service
• Internal drive rebuild — all sealing rings encountered during disassembly should be replaced as a matter of course; do not selectively reuse rings to save cost on a rebuild

Confirming the Correct Sealing Ring for Your Application:

Volvo Penta uses sealing rings in multiple locations across its sterndrive and engine product line — shaft seals, plug seals, housing seals, and O-ring-style sealing rings are all used in different applications and are not interchangeable. The 3593663 / 851979 / 873108 cross-reference group identifies a specific sealing ring within the Volvo Penta parts catalog. Verify the part number against your drive or engine's parts diagram using your model and serial number before ordering to confirm this is the correct ring for your specific application.

Frequently Asked Questions

1. How do I confirm this sealing ring fits my Volvo Penta drive or engine?
Cross-reference part #3593663 — or the superseded numbers 851979, 873108, 23370796, or 3582889 — against your Volvo Penta sterndrive or engine parts diagram using your model and serial number. Contact us at MacombMarineParts.com with your drive model and serial number and we'll confirm the correct part before you order.

2. Can I reuse the existing sealing ring when servicing my drive?
No — sealing rings are single-use components. They deform on installation to create their seal and cannot reliably re-seal after removal. Always install a new sealing ring whenever the sealed joint is disassembled, regardless of how the old ring looks visually.

3. How many sealing rings does a Volvo Penta sterndrive service typically require?
The number varies by service type and drive model. A gear lube change typically requires one or two sealing rings at drain and fill plugs. A full drive removal for bellows or gimbal bearing service requires additional rings at the drive-to-transom interface. A complete internal drive rebuild requires all sealing rings throughout the unit. Refer to your Volvo Penta sterndrive service manual for the complete sealing ring requirements for your specific service procedure.
