Volvo Penta Seawater Pump Gasket 819959
When you open the seawater pump for impeller service or repair, gasket 819959 seals the pump joint to help prevent raw-water leaks. It is used in selected Volvo Penta flexible-impeller pump assemblies, but the correct match depends on the pump fitted to your engine.
Compatible Applications
- D1-30, D1-30B, D1-30F
- D2-40, D2-40B, D2-40F
- MD2010B, MD2010C, MD2010D
- MD2020B, MD2020C, MD2020D
- MD2030B, MD2030C, MD2030D
- MD2040B, MD2040C, MD2040D
- Earlier pump-diagram applications include MD17D, AQ130A, AQ130C and AQ170C.
Confirm the part number against the engine serial number and the seawater-pump diagram. Volvo Penta used different pump versions within some engine families, and a pump may have been replaced during previous service.

Key Features

When to Replace
Renew gasket 819959 whenever the corresponding pump joint is opened if the existing gasket is compressed, hardened, torn or damaged. Replace it if seawater seepage is visible around the joint.
Installation Notes
Clean the mating surfaces and remove old gasket material before fitting the replacement. Inspect the cover, cam, impeller, sealing rings, shaft and pump body while the assembly is open. Follow the service procedure for the specific engine and pump; do not add sealant unless that procedure calls for it.
Alternate Part Reference
Part 840385 is shown at the corresponding position in some MD17D pump diagrams. Treat it as an earlier or alternate diagram reference, not a confirmed direct supersession. Check the engine serial number and pump diagram before ordering.
Related Products
- Volvo Penta Impeller Kit 22222936 — a raw-water pump service kit listed for many D1, D2, MD and classic AQ applications. Its listing mentions sealing gasket(s); confirm the kit contents for your pump and do not assume it includes gasket 819959.
- Volvo Penta Seawater Pump 3593655 — the complete pump assembly associated with 819959 on documented D1-30F and MD2030B diagrams. This is a pump assembly, not the gasket.
- Volvo Penta Seawater Pump 3593654 — a related smaller-engine pump listing for D1-13, D1-20, MD2010 and MD2020 applications. It is a different pump reference and does not by itself confirm gasket 819959 fitment.
Parts Desk Insights
Best use: Replace this gasket when servicing or reopening the matching seawater-pump joint.
Common mistake: Ordering by engine family alone, or assuming a similar-looking pump uses the same gasket. Match the actual pump diagram and serial number.
Sizing and fitment: No verified dimensions are provided here. Use the engine serial number and pump configuration as the primary fitment check, with the old gasket's shape only as a secondary comparison.
