The Volvo Penta Seawater Pump 24346053 is a heavy-duty raw-water cooling pump used in Volvo Penta D13 marine diesel cooling systems. It circulates seawater through the heat-exchanger side of the cooling system to help control engine temperature under load. Replacement-chain references show earlier seawater pump 23271278 replaced by 24346053, and parts-diagram data for 23271278 identifies it as the seawater pump / wear part set at diagram position 1 in the heat-exchanger seawater pump assembly.

Serial Number Fitment Notice
Confirm fitment by engine serial number, existing pump number, and the Volvo Penta cooling-system diagram before ordering. Replacement-chain data should be checked carefully because some catalog references show 23271278 → 24346053, while another current catalog route shows 23271278 → 24883556. The safest match is the active Volvo Penta serial-number lookup for the exact engine.
When This Part Needs Replacement
Replace the seawater pump if the engine is overheating, raw-water flow is weak, the pump leaks, the shaft or bearings are worn, the pump body or cam area is damaged, or repeated impeller failures point to internal pump wear. Saltwater leakage around the pump should be corrected quickly to prevent damage to belts, brackets, fittings, and surrounding engine components.
Installation Notes
Inspect the full pump assembly before replacing the pump alone. Check the pump gear, shaft, bearing housing, O-rings, sealing rings, cam, impeller kit, end cover, fasteners, and heat-exchanger seawater hoses. Diagram references show many pump components sold separately, so confirm whether the repair requires the complete pump, a wear part set, or individual service parts.
Alternate/Superseded Part Numbers

Parts Desk Insight
The key detail on this pump is the replacement chain. 24346053 is tied to earlier D13 seawater pump 23271278, but replacement references can vary by engine build. Matching the engine serial number and existing pump number helps ensure the correct D13 raw-water pump is ordered the first time.
