🔌 Function

Draws raw sea water in through the inlet and pushes it through the heat exchanger and oil cooler, carrying the engine's heat overboard with the exhaust.

⚠️ Common Signs of Failure

• Little or no water at the exhaust outlet
• Engine temperature climbing under sustained load
• Water dripping from the pump's telltale or body joint
• Squeal, rumble or play felt at the pump shaft
• Impeller found with vanes worn, set or broken away

🛠️ Service Notes

• Renew the impeller on the published interval and keep a spare aboard — a failed impeller can overheat the engine and the exhaust hose within minutes
• Always find and remove every broken impeller vane from downstream before restarting, or the exchanger will block
• Check the raw water strainer and hose 859809, which runs from the sea water pump to the heat exchanger, at the same time
