The Volvo Penta Seawater Pump 3593654 is a genuine Volvo Penta raw-water cooling pump used on select small Volvo Penta marine diesel engines. It circulates seawater through the raw-water side of the cooling system to help keep engine temperature under control while running. Current parts references show 3593654 as a seawater pump that replaces earlier Volvo Penta pump number 3580944, with additional replacement references commonly listing 3580064 and 3580900 in the same pump family.

Engine Compatibility
Confirmed application references include:
- D1-13A / D1-13B / D1-13F
- D1-20A / D1-20B / D1-20F
- MD2010A / MD2010B / MD2010C / MD2010D
- MD2020A / MD2020B / MD2020C / MD2020D
Some catalog references also associate this pump with MD2030-C / MD2030-D and MD2040-C / MD2040-D, but those applications should be checked by engine serial number and existing pump number before ordering.
Serial Number Fitment Notice
Confirm fitment using the engine serial number, existing pump number, hose layout, and Volvo Penta cooling-system diagram. Small Volvo Penta diesel engines can use similar-looking seawater pumps with different mounting, gear, seal, or service-part arrangements. Several parts references specifically advise checking the pump number or serial number because early models may use an alternate pump.
When This Part Needs Replacement
Replace the seawater pump if the engine is overheating, raw-water flow is weak, the pump is leaking, the shaft or bearings are worn, the pump body is damaged, or repeated impeller failures point to internal pump wear. A leaking seawater pump should be corrected quickly because saltwater around the front of the engine can damage belts, mounts, brackets, and electrical components.
Installation Notes
Inspect the impeller, cover, gasket, lip seals, shaft, bearings, O-rings, hose connections, and mounting hardware before replacing the pump. If the pump body is still serviceable, a shaft kit, wear kit, impeller kit, or screw kit may solve the issue; if the body, shaft bore, or bearing area is worn, replacing the full pump assembly is usually the cleaner repair. Related service references include shaft service kit 21951416, wear kit 21951370, screw kit 21951302, and impeller 3593659 where applicable.

Parts Desk Insight
The key detail on 3593654 is separating it from the larger D1-30 / D2-40 style pump. For the safest match, check the existing pump number and engine serial before ordering, especially on MD-series engines where similar pumps can appear across different model years.
