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.\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003ePart Details:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 3593663 (Recmar)\u003c\/li\u003e\n\u003cli\u003eSKU: RECMAR-REC3593663\u003c\/li\u003e\n\u003cli\u003eManufacturer: Recmar (aftermarket)\u003c\/li\u003e\n\u003cli\u003eType: Sealing Ring\u003c\/li\u003e\n\u003cli\u003eReplaces Volvo Penta: 851979, 873108, 23370796, 3582889, 3593663\u003c\/li\u003e\n\u003cli\u003eApplication: Volvo Penta sterndrive and marine engine — verify fitment against your drive or engine parts diagram before ordering\u003c\/li\u003e\n\u003cli\u003eCondition: New\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch5\u003eAdditional Information\u003c\/h5\u003e\u003cp\u003e\u003cstrong\u003eWhen to Replace a Volvo Penta Sealing Ring:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSealing 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.

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.\u003c\/p\u003e\u003ch5\u003eFrequently Asked Questions\u003c\/h5\u003e\u003cp\u003e\u003cstrong\u003e1. How do I confirm this sealing ring fits my Volvo Penta drive or engine?\u003c\/strong\u003e\u003cbr\u003eCross-reference part #3593663 — or the superseded numbers 851979, 873108, 23370796, or 3582889 — against your Volvo Penta sterndrive or engine parts diagram using your model and serial number.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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e2. Can I reuse the existing sealing ring when servicing my drive?\u003c\/strong\u003e\u003cbr\u003eNo — 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e3. How many sealing rings does a Volvo Penta sterndrive service typically require?\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e","brand":"Recmar","offers":[{"title":"Default Title","offer_id":51914681254208,"sku":"RECMAR-REC3593663","price":10.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2712\/8720\/files\/Sealing-Ring-Volvo-Penta-Recmar-3593663.webp?v=1779770375","url":"https:\/\/www.macombmarineparts.com\/products\/sealing-ring-volvo-penta-recmar-3593663","provider":"MacombMarineParts.com","version":"1.0","type":"link"}
