Engineered Marine Products 47-01865 OMC Water Pump Impeller 20-35HP

The Engineered Marine Products 47-01865 is a replacement water pump impeller designed for OMC (Johnson/Evinrude) outboard motors in the 20-35 horsepower range. This impeller is a critical component of the engine's cooling system, responsible for drawing water from the intake and circulating it through the powerhead to prevent overheating.

Key Features:

• Direct replacement for OMC original equipment impellers
• Compatible with 20-35HP Johnson and Evinrude outboard motors
• Constructed from durable neoprene rubber for reliable performance
• Precision-molded blades ensure proper water flow and cooling efficiency
• Essential maintenance component for outboard motor longevity

Regular impeller replacement is recommended as part of routine outboard maintenance, typically every 2-3 years or 200-300 hours of operation. A worn or damaged impeller can lead to inadequate cooling and serious engine damage. Always inspect your impeller annually and replace if blades show signs of cracking, wear, or deformation.
