Yanmar neoprene impeller 1GM/1GM10 – 128176-42071

Yanmar impeller 128176-42071 is an original neoprene impeller for the cooling water pump of compact Yanmar marine diesel engines, including the 1GM and 1GM10 series. This rubber impeller ensures the supply and circulation of seawater through the cooling system, so the engine remains at the correct temperature. A worn, dried-out or deformed impeller can lead to insufficient cooling water flow, overheating and serious engine damage. Annual inspection or replacement is therefore important for reliable operation of the cooling water pump.

Main features and benefits:

Neoprene impeller: Flexible and durable rubber for reliable cooling water circulation.
Prevents overheating: Ensures sufficient supply of seawater to the cooling system.
For Yanmar 1GM and 1GM10: Suitable for compact single-cylinder Yanmar marine diesel engines.
Essential maintenance part: Recommended for annual inspection or replacement.
Protects the engine: Helps prevent damage caused by reduced cooling water flow.
Original Yanmar part: Guarantees a perfect fit and reliable operation.
