882710 882710001 Mercruiser Water Pump Assy | Genuine Used Part

🔧 Product Description

Genuine MerCruiser 1.7L Diesel Engine Coolant Pump Assembly - Part Numbers: 882710 / 882710001

A genuine used belt-driven engine coolant circulation pump for the MerCruiser D1.7L DTI and CMD 1.7L-120 marine diesel.

This is the closed-circuit engine pump rather than the sterndrive seawater impeller pump. It circulates treated coolant through the engine block, cylinder head and heat exchanger. The later 882710001 service number replaces the original 882710 pump reference.

🔌 Function

The pump circulates engine coolant through the block, cylinder head and heat exchanger. It allows heat absorbed by the coolant to be transferred to the raw-water circuit.

⚠️ Common Signs of Failure

• Coolant leakage from the pump shaft or mounting joint
• Engine overheats despite correct seawater flow
• Bearing noise or roughness from the pump
• Pulley or shaft develops visible wobble
• Coolant circulation is reduced by a damaged internal impeller
