Forgot about this project! Looking mean. Valvoline 2 stroke eggbeater oil has always treated me well. Good price at Supercheap when on special.

There are some pics further back but I'm using a Skat trak Kawasaki front impeller progressive 16-21.
Rear is JJ custom 4 blader 24 deg duplex 2205 parallel hub beast.
Hopefully turns stones into smoke....
I have shoved 5x ball bearings in pump.
Stator/bearing assembly and the 2x wear rings are all one piece machined as a whole so impeller alignment is perfect and can get tight tolerances. (Not that they will be for long)  ::)

Lip seals and wear sleeves, 2 in front and 3 in back.
Front of rear impeller is counter bored so close to bearings.
Similar to jetski pump setup.

It's the forum software - not Aunty.  It's been in place for many years, there's only a few triggers.
