Fitment Notice
Match this kit to your pump model number stamped on the pump housing, not just the engine model or horsepower. F35B pumps were produced in multiple configurations; service-kit compatibility can vary by pump version and seal arrangement. If you are unsure of the pump model, confirm the impeller number currently fitted — this kit includes the 09-808B-1 impeller. Match that number to what is in your pump before ordering.
Service Interval
Johnson Pump recommends inspecting flexible impeller pumps at least annually and servicing them based on condition. As a general guideline:
- Inspect the impeller at every season start
- Replace the impeller at the first sign of cracking, hardening, missing blades, or reduced output
- Replace seals, O-ring, and gasket whenever the pump is opened for impeller replacement
- Service the complete pump if it has run dry or overheated
A full service kit makes it practical to replace all wear items in a single visit rather than sourcing components individually.
Installation Notes
- Close the raw-water intake seacock before disassembly
- Remove the pump cover and extract the old impeller — inspect all blades and locate any missing pieces before proceeding
- If blade fragments are missing, flush and inspect all downstream cooling passages and the heat exchanger before reassembling
- Replace all seals, O-ring, and gasket included in the kit — do not reuse old sealing components
- Inspect the pump housing bore and cam for scoring or wear; replace the housing if damaged
- Lubricate the new impeller with the included service grease before fitting
- Rotate the shaft in the normal running direction while seating the impeller to pre-set vane direction
- Fit the new cover gasket and reinstall the cover with the supplied screws
- Check for leaks and verify cooling-water flow at the exhaust outlet after startup

Parts Desk Insights
Best use case: The 09-45589 kit is the right choice when you are already in the F35B pump for impeller replacement and want to address all the wear items at once. Buying the full kit is almost always more cost-effective than sourcing the impeller, seals, O-ring, gasket, and screws separately, and it ensures all sealing surfaces are renewed at the same time — particularly important on pumps with high hours or any history of running dry.
Common issue: The most frequent mistake is ordering by pump size or engine model rather than the stamped pump model number. The F35B family has several variants (F35B-8, F35B-8007, F35B-9), and while they share the same impeller, the seal and gasket configuration can differ. Always confirm the full pump model number before ordering this kit. If any impeller blades are missing after removal, do not return the engine to service until the fragments have been located and removed from the cooling circuit.
