🔌 Function

Draws raw water in through the hull fitting and pushes it through the heat exchanger and exhaust injection, carrying engine heat overboard.

⚠️ Common Signs of Failure

• Little or no water at the exhaust outlet
• Coolant or exhaust temperature climbing while raw water flow drops
• Water weeping from the pump body or dripping from the weep hole below the seal
• Squealing, rumbling or roughness from the pump as the bearings go
• Impeller found with vanes worn, torn or missing

🛠️ Service Notes

• Three of the four pumps in this group are TAMD listings within 400 grams of each other, so match the part number and the superseded number rather than trusting the weight
• Renew the impeller, cover gasket and any shaft seal at the same time, and check the heat exchanger for impeller debris
• Never run a raw water pump dry, even briefly
