Flexible Impeller Kit 4528-0001 09-806B for Jabsco Johnson Volvo Yanmar Sherwood Pump
Flexible Impeller Kit 4528-0001 09-806B for Jabsco Johnson Volvo Yanmar Sherwood Pump
Product Overview
Flexible impeller kit for Jabsco, Johnson, Volvo Penta, Yanmar, Sherwood, Onan and Perkins pumps, 6 blades, 40 mm diameter, 19.0 mm wide, 9.5 mm shaft bore, supplied as 1 x impeller, 1 x O-ring and 2 x gaskets, replacing 4528-0001, 09-806B, 803729 and 104211-42070.
The impeller is the same 6 blade 40 mm neoprene star that Jabsco, Johnson, Sherwood, Volvo, Yanmar, Onan and Perkins all buy onto their own shaft and housing. Cross reference the number on your old impeller against the table below before ordering.
These pumps run dry without complaint until the blades take a set, and then the flow falls away and the motor starts to run hot. On a diesel the first sign is usually a warmer exhaust elbow rather than an alarm.
