Flexible Impeller Kit 09-810B 653-0001 51 mm for Johnson F4 Jabsco Yanmar 3GM30 Volvo Westerbeke — Australia Local Warehouse
Product Overview
Flexible impeller kit measuring 51 mm outside diameter by 22 mm wide with 6 blades on a 12 mm slotted pin drive, a raw water pump service part supplied with the gasket and O-ring. It replaces Johnson 09-810B, Jabsco 653-0001, Sierra 18-45713, Mallory 9-45713, Westerbeke 34440, Yanmar 128990-42200 and Volvo Penta 876097, and fits every pump built on the Johnson F4 and Jabsco 29460 / 29470 bodies. Held in our Australia local warehouse.
The badge on the pump tells you who sold it, not whose impeller you need. Johnson, Jabsco, SPX, BLA, CEF, JMP, Northern Lights, Westerbeke, Beta Marine, Volvo Penta and Yanmar all used the same body, so the number on the old impeller can be any of half a dozen.
On a raw water cooled diesel the impeller is the whole cooling system. A set of blades that have taken their folded shape still turn and still look intact, but the pump moves far less water than it should, and the first sign is usually a hot exhaust elbow or a softened exhaust hose.

Heat, Silt and Long Days on the Water
| What the Owner Finds | Why It Happens Here | What to Do |
|---|---|---|
| Water flow drops off on a hot day | Blades softened by heat and set by the cam | Fit a new impeller before the reef trip |
| Genset overheats on a trawler after hours of running | Fixed speed sets the blades in one position | Keep two spare kits aboard |
| Mud and sand through the strainer | Shallow estuary work wears blade tips | Flush after every trip, inspect monthly |
| Impeller spins on the shaft | Brass insert worn, blades still look good | New kit, the insert is the failure |
| Exhaust hose gone soft | Water flow below what the engine needs | Renew the impeller first, then the hose |
| Boat sitting between trips in the wet season | Blades set in the folded position | New kit at the start of each season |
Fitting Notes
| Step | Action |
|---|---|
| 1 | Measure the old impeller, 51 mm diameter by 22 mm wide, the F3 pump takes a 40 mm impeller and it will not fit |
| 2 | Check whether the shaft is 12 mm or 3/8 in on the F4B, the pump was sold in both versions |
| 3 | Check the insert is brass and not bare rubber, a worn insert will spin on the shaft |
| 4 | Inspect the pump cover plate for scoring, a grooved plate lets water bypass the new impeller |
| 5 | Lubricate the impeller with glycerine before fitting, never install it dry |
| 6 | Turn the shaft by hand after fitting to confirm the blades fold in the correct direction |
| 7 | Look for water under the pump after the first run, a weeping cover gasket is common after a rebuild |
| 8 | Carry a spare kit and the tools to change it, the pump never fails at the dock |
