Product Details

The WSM 700-403 is a precision-engineered replacement water pump impeller designed specifically for Mariner 8 HP through 15 HP outboard motors. This critical cooling system component circulates water through the engine block to prevent overheating and ensure optimal performance.

Key Features:

  • Direct replacement impeller for Mariner 8-15 HP outboard engines
  • Constructed from durable neoprene rubber for reliable performance and longevity
  • Precision-molded blades ensure proper water flow and pressure
  • Designed to meet or exceed OEM specifications
  • Essential preventative maintenance component to avoid costly overheating damage

Regular impeller replacement is recommended as part of routine outboard maintenance, typically every 2-3 years or 200-300 hours of operation. A failing impeller can lead to engine overheating, reduced performance, and potential engine damage. WSM marine products are manufactured to provide reliable performance for recreational and commercial marine applications.
