🔧 Product Description

🚤 Compatibility

• Volvo Penta TAMD122A

• Engine Family: TAMD

⚙️ Key Features

• 2 inch
• 8.414 kg
• 3 applications on TAMD series engines
• Supersedes 845189

🔌 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

• Seawater pump 3829310 at 8.518 kg carries the same 3 TAMD applications and sits only 104 grams away, so weight cannot separate them — the 2 inch marking and the superseded number are the difference
• 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
