impeller choice with 148mm setback magpump

[Berky]

Hey Lerott,

If your sure it's not sucking air (mid shaft, pump seal, wear ring) , you can : go with a big intake grate, big pump cone, small reduction nozzle, fair out the pump ring area, set back the current prop 2mm from leading edge of stator veins if this doesn't work you need a bigger prop.

Thank you berky.
I have swap back my nozzle and I need to go to the water for test ride.

what was your reduction nozzle diameter for the record. I will probably go with 86-87mm but with my smaller motor may have to go even bigger.

My reduction nozzle is 85 mm.
