Have water coming out of the intake when it is on the hose.
I can't see far enough in to see exactly where it might be coming from.
I had the bowl off to install a new bowl seal. I also used all new gaskets putting it back together.
Mine has a 'T' just after the gate valve off of the pump, and water goes both ways- to the motor and to the pump, helps keeping the wear ring/impeller lubed/cool. Some of the water drains out the pump intake, even after the hose is off.
If you hooked up the hose to a "T" then water is flowing 2 directions. Through the engine and backwards through intake, which is why this is happening. The attached pic is the giveaway. Looks like your jet is taking a leak
