Heh, it’s a compliment that you think Marc did this! It was actually me.

I stand corrected and I like the way you think. :)
NICE job!
Btw, I looked at your profile to see where you're located but it was blank. Do you prefer it that way? lol

I'm just guessing that the connection you're using is the flush connection, just trying to be helpful.
The flush connection I think feeds the motor but not the impeller, they had an attachment for that.


Thanks for the concern. No actually the Mark 75 does not even have that flush valve on the gear housing. I actually made my own attachment to go on the bottom since trying to find one like you just posted is virtually impossible. I essentially molded mine to the existing motor and added clay where I wanted a bulge for the water to flow through:

Rick, I TIG welded it. It’s really the only way to properly repair it.
