Johnson Pump 10-24228-1 F5B-9 Crankshaft Impeller Pump for Small Block GM Marine Engines

The Johnson Pump 10-24228-1 is a crankshaft-mounted impeller pump built for F5B-9 pumps, designed as the engine-driven raw water cooling pump on older style small block GM marine engines. Unlike belt-driven or electric auxiliary pumps, this crankshaft pump mounts directly to the engine and is turned by the crankshaft itself, delivering cooling water flow as long as the engine is running.

The pump body is bronze for corrosion resistance and long service life in raw water cooling applications, and it uses a 1-1/4 inch hose port for the water connection. As a direct-fit replacement part, it is intended for boat owners and marine technicians servicing small block GM inboard and sterndrive engines that use the F5B-9 style crankshaft pump.
