Other Waverunner III (701) pump the same as RN Superjet?

As the title says. Are the pumps interchangeable? Stator, wear ring, reduction nozzle turn nozzle etc.?
I know they are both listed as 144mm but I can't determine if they are a direct bolt in.

yes depending on year anything past 08 no but before yes just need to use a differesnt driveshaft

what about the bilge? most wr3's i have seen have the stock syphon bilge off the pump vane with the little syphon valve bolted to the ride plate. It will work if your useing your stock ride plate since it has the holes already for the syphon valve.

Perfect. You have confirmed my suspicions.

Stators are same or similiar except for the oem bilge variations. Wear ring isnt threaded for long bolts like sj, but can be helicoiled. Long bolts need to be cut shorter. Reduction nozzle can be used, but steering nozzle is different. Driveshaft is different length, but can be modded to correct length.

Various 144 yami models is where i go a bit astray but when i saw this thread i knew ^ he was gonna have the answer!

Hows it work out if you use one of those reduction nozzles with the vanes or fins inside them? I have a few WR3 pumps maybe I can attempt to make one good pump, probably buy a new wear ring tho.
