Flexible Impeller Kit 51 mm 09-824P 6303-0003 for Jabsco Johnson Yanmar Oberdorfer Pump with O-Ring — Australia Local Warehouse
Product Overview
Flexible impeller kit with the pump cover O-ring, 6 blades, 51 mm diameter and 22 mm wide. It replaces Jabsco 6303-0003, Johnson 09-824P, Yanmar 124223-42092 and Oberdorfer 7482 pumps, and crosses to Sierra 18-30005, Vetus IMP00101, CEF 500210 and Milwaukee 49-16-2771. The impeller itself is H-157. Dispatched from our Australia local warehouse.
One rubber wheel covers an odd spread of equipment: toilet pumps on trailer boats, washdown pumps, live bait tank pumps and the raw water pump on small Yanmars. They all use the same 51 mm body with a single flat drive and a brass insert.
Sand is what kills these in Australia. A trip up a shallow creek pulls grit through the pump, the blades scuff the cover plate, and the impeller starts slipping on the shaft instead of pushing water. The O-ring is in the box because the old one is usually flat by the time the impeller fails.

Signs It Needs Changing
| What You Notice | What It Means |
|---|---|
| Water flow drops at idle | Blade tips worn or set |
| Pump squeals when switched on | Running dry, insert slipping |
| Rubber dust in the pump body | Blades breaking up |
| Flow stops as revs rise | Vanes folding back, impeller too soft |
| Water in the bilge under the pump | Cover O-ring flat |
| Impeller turns on the shaft | Brass insert spun, shaft flat worn |
Fitting Notes
| Step | Action |
|---|---|
| 1 | Close the seacock and drain the pump body |
| 2 | Take the cover off and note which way the blades lean |
| 3 | Pull the old impeller with two screwdrivers, never a blade |
| 4 | Wipe the pump body and check the cover plate for scoring |
| 5 | Check the shaft flat, a rounded flat will spin the new insert |
| 6 | Lubricate with glycerine or soap, never grease or oil |
| 7 | Fold the blades in the direction of rotation as the cover goes on |
| 8 | Fit the new O-ring, open the seacock and check flow before loading it |
