🔌 Function

Draws raw water in through the intake and pushes it through the cooling circuit, carrying engine heat overboard with the exhaust.

⚠️ Common Signs of Failure

• Weak or absent water flow at the exhaust outlet
• Overheating under load with a clear intake and strainer
• Salt trails or drips from the pump body and shaft area
• Pieces of impeller vane found downstream in hoses or the cooler
• Bearing noise or shaft play felt at the drive end

🛠️ Service Notes

• Seawater pump 837370 is the near twin, 18 grams heavier at 4.831 kg, but it supersedes 824385 rather than 822459 and covers 20 applications rather than 29, so order by part number and not by weight
• This pump sits under the Industrial and Marine Equipment heading while its twin sits under Cooling System, so search by number
• Renew the impeller, cover gasket and shaft seal whenever the pump is stripped
