Volvo Penta 21951476 is an OEM seawater pump used in the raw-water cooling circuit on compatible Volvo Penta marine engines. The pump draws seawater through the intake and circulates it through the engine’s cooling system, helping remove heat and maintain proper operating temperature. The pump is part of the F7 flexible-impeller pump family and shares service components with Volvo Penta seawater pump references 3583115 and 3583145.
Key Features
- Genuine Volvo Penta seawater pump reference 21951476
- Flexible-impeller raw-water cooling pump
- Used to circulate seawater through the marine cooling system
- Part of the F7 pump family
- Compatible with F7 wear-service components
- Associated pump references include 3583115 and 3583145 for service-component compatibility
Engine Compatibility
Part 21951476 is associated with the same F7 seawater-pump family as Volvo Penta 3583115. The 3583115 pump family is used across numerous Volvo Penta diesel applications, including engine families such as:
- AD31 / D31 / TAMD31 / TMD31
- AD41 / D41 / TAMD41 / TMD41
- KAD32
- KAD42 / KAMD42
- KAD43 / KAMD43
- KAD44 / KAMD44
- KAD300 / KAMD300
Because pump configuration can vary between individual engine versions and production ranges, 21951476 should be verified directly against the engine serial number before ordering.
Serial Number Fitment Notice
Confirm 21951476 using the Volvo Penta engine model and serial number before installation. Similar engines may use different seawater-pump housings, hose connections or drive arrangements even when the pumps appear similar externally.
When This Part Needs Replacement
Replace the seawater pump if it develops shaft or housing leakage, excessive bearing or shaft play, physical damage, reduced seawater flow, or internal wear that cannot be corrected with normal impeller or wear-component service. Repeated impeller failures or persistent overheating can also indicate that the complete pump requires inspection.
Installation Notes
Inspect the complete raw-water circuit while replacing the pump, including the seawater intake, hoses, clamps, impeller, wear surfaces and downstream heat-exchanger passages. F7 wear kits compatible with 21951476 include an end cover, lip seal, two O-rings, washer and wear plate, allowing common wear components to be serviced when the pump body and shaft remain usable.
Always prime the seawater circuit as required and verify strong raw-water discharge and leak-free operation after installation. Never operate a flexible-impeller seawater pump dry.
Alternate/Superseded Part Numbers
Related Volvo Penta pump references within the same service family include:
- 21951476 – Volvo Penta seawater pump
- 3583115 – Related Volvo Penta F7 seawater-pump reference
- 3583145 – Related Volvo Penta F7 seawater-pump reference
These references share certain F7 service components, but they should not automatically be treated as interchangeable complete pumps without confirming the engine and pump configuration.
Parts Desk Insight
With seawater pumps, the housing and hose arrangement matters just as much as the impeller size. 21951476 shares F7 service parts with other Volvo Penta pumps, but that does not automatically make the complete pumps interchangeable. Match the exact pump number and engine serial number before ordering.
