Flexible Impeller Kit 51 mm 6303-0003 for Jabsco TMC Toilet Johnson 09-824P Yanmar Pump O-Ring — United Kingdom Local Warehouse
Product Overview
Flexible impeller kit, 6 blades, 51 mm diameter by 22 mm wide, 8 mm shaft bore, with the cover O-ring in the box. It replaces Jabsco 6303-0003, Johnson 09-824P, Yanmar 124223-42092 and Oberdorfer 7482, and fits pumps sold as Sierra 18-30005, Vetus IMP00101, CEF 500210, Ancor J050016 and Milwaukee 49-16-2771. The impeller is H-157. Held in our United Kingdom local warehouse.
The single biggest use for this one in the UK is the electric toilet. A Jabsco or TMC pump head running on a 51 mm impeller, usually blamed for a bowl that will not empty, and usually fixed by this part rather than by a new toilet.
Narrowboats and river cruisers are harder on these pumps than sea boats are. River water carries silt that scours the cover plate, and a pump that runs dry even once will spin the brass insert and finish the impeller in seconds. Both faults show up as weak flow long before the pump stops working.

Before You Buy
- Check the number on the old impeller or on the pump cover
- Measure the old part, 51 mm body, 22 mm wide, 8 mm shaft
- Look at the shaft flat, a rounded flat needs a shaft not an impeller
- Toilet trouble with water running back is usually the joker valve
- Use glycerine or soap to lubricate, never grease or oil
- This is the impeller and O-ring, the pump body is not included
- 30-Day Easy Returns
- Ships from our UK local warehouse
