So I need to flush the antifreeze and do some (extensive) carb tuning, so I was going to run the engine on the hose this weekend. I have one of the "Y" fittings to run 2 garden hoses, one to the engine and the other to the pump.
Instead of the convoluted deal trying to squirt water up thru the intake, what about just shoving the hose up the nozzle and into a bowl vein, and letting the water splash around in there while the hose runs? The only thing the water is doing is lube the impeller and wear ring, right? So the pump wont care that the water isnt coming in the right end? And I doubt there is any water splashing up to the shaft bearing anyway, regardless of which direction the water is coming from.
Oh- and before i get scolded for running the pump out of the water, this isnt some newly rebuilt super tight detailed prize pump. its an old lake boat.
