Product Details

The Johnson Pumps F5B-9 is a professional-grade flexible impeller pump designed for marine engine cooling and raw water handling applications. This OEM replacement pump delivers reliable performance for inboard marine engines and diesel applications.

Key Features:

  • Bronze pump body construction with stainless steel shaft for superior corrosion resistance in marine environments
  • Neoprene flexible impeller provides self-priming capability up to 15 feet of suction lift
  • 3/4" NPT inlet and outlet ports for efficient water flow
  • Flange mount design for secure installation
  • Full cam configuration for optimal impeller performance
  • Mechanical shaft seal provides leak-free operation
  • Can pass large solids without clogging or damage to pump

Applications: Commonly used on Ford Lehman SP90 and SP135 marine diesel engines, American Diesel 4-cylinder engines, Bomac Marine, and various marine engine cooling systems. Ideal for raw water pumping, bilge pumping, deck wash systems, and holding tank applications.

Note: This pump is sold as pump end only and does not include drive gear. Drive gear must be transferred from existing pump. The flexible impeller must be kept lubricated by the liquid being pumped to prevent rapid degradation from dry running.
