MC97 has been developed to meet new environmental regulations for rubber manufacturing processes and will replace the regular Johnson neoprene impeller compound. The development of MC97 has also resulted in an extended service life of the impeller compared to impellers in neoprene.

The Johnson pump flexible impeller has six blades and is supplied complete with standard gaskets, O-ring, lubrication gel and instruction manual to aid installation of the impeller into the flexible impeller pump.

The Johnson 09-810B-1 can be used to replace the Yanmar 128397-42200 and Jabsco 18653-0001 (Europe and USA) flexible impellers. For applications containing diesel or light oils, use Johnson nitrile impeller 09-810B-9.

It is highly recommended to make sure you use an original pump impeller for your flexible impeller pump as this will ensure that the quality complies with the performance and dimension requirements for each pump type. Johnson Pump impellers are manufactured in strict compliance with the pump specifications set by the engine manufacturers they supply.

Impeller fits the following engines:

- Beta Marine Beta 10 hp, Beta 14 (13.5hp), Beta 16 hp, Beta 20 hp, Beta 25 hp, Beta 28 hp, Beta 35 hp, Beta 38 (37.5hp), BD722 (20hp), BD1005 (28hp), BF2803 (62hp), BV1305 (32hp), BV1505 (37.5hp), BV1903 (43hp), BV2203 (50hp), BZ482 (13.5hp), KC, 2KC & KR
