Product Details

The Sierra 18-45003 is a precision-engineered water pump impeller designed for Chrysler Force outboard motors ranging from 35 to 55 horsepower, manufactured between 1974 and 1980. This critical cooling system component ensures proper water circulation through your outboard engine to prevent overheating and maintain optimal operating temperatures.

Key Features:

  • Direct replacement for Chrysler Force OEM part number 47-F436065
  • Precision-molded neoprene construction for durability and reliable performance
  • Fits Chrysler Force 35HP, 40HP, 45HP, 50HP, and 55HP outboard motors (1974-1980)
  • Premium aftermarket quality from Sierra Marine, a trusted name in marine parts
  • Designed to meet or exceed OEM specifications

Regular impeller replacement is essential preventive maintenance for any outboard motor. Marine technicians recommend inspecting your impeller annually and replacing it every 2-3 years or sooner if signs of wear are detected. A failed impeller can lead to engine overheating and serious damage, making this an important service item to keep on hand.
