Muncie OB-5 impeller

[russ]

I have a muncie ob-5 that runs very well.Cannot see any water coming out exhaust.I removed the copper tube on the bottom of the power head to check but no water.Could someone tell where I could find the impeller so I can have a look.I think they have a brass impeller but not sure .Thank you very much.

They are aluminum…..if memory serves…right above the cavitation plate, check for blockages in the cooling system as well..

Hi
That motors pump my be in the mid section as well, The pumps rarely fail if your pump is OK Check as Richard said for blockage. These motors have cast iron jugs if sitting for long periods they will dry out and large chunks of rust will flake off clogging up exit ports.
