Another boat question

Lol, me too Doug. I cleaned out tell tale, no change.... changed impeller and same weak stream. Took airline and blew into the water intake and voila! Changed damn impeller for no reason.
The garden hose in your pic, is that a type of flush? Mine has attachment but ive never used it.
I've always used muffs to run water(chance of false psi tho)
Anyone else suffer from a weak stream?

lol! Cleanup sux.
Seriously though I think mine may have a thermostat, it seems to pick up after awhile.
