JOHNSON PUMP
Pumpendeckel für Seewasserpumpe F4B
Other material
The lid supplied is made of V2/V4 stainless steel and lacks the Johnson logo – it does not match the image. Apparently not a genuine Johnson part!

JOHNSON PUMP
Impeller / MC97 / 6 Flügel / Typ 2
Johnson SPX impellers - the best!!!
These impellers don't use a setscrew as a drive pin, but rather a threadless bolt. That's how it should be, because it protects the pump shaft. All other aftermarket impellers, with their completely pointless threads, damage the groove in the shaft due to the radial movements caused by the pressure cam. Furthermore, the blade material is more elastic and doesn't crack as easily.
