Exhaust flush connector exit

[lineofsight]

Hi, just curious where the exit is for the exhaust flush port the Challenger 210 SE 310hp. Ran motor briefly to stall it on fogging oil (so 15 seconds if that). Some water expelled. Connected air compressor to flush port and some more water was expelled that dripped out of impeller intake / grate. Peeked in could not see an obvious exit drain (is a slight bulge off to one side). So when using the flush port, where does water/air expel, what stops it from flowing into manifold / cylinder?

Boat ran fantastic this summer, surprises people when can rotate in place at dock and even more so when can spin it at speed. Kids became tubing addicts.

Got it, thank you.

"exhaust cooling is raw water fed from the pressure of the jet pump. Small holes at the top of the jet pump divert a small quantity of pressurized raw water to run through and cool the exhaust system."

From the posted diagram it looks like air travels in reverse connection from cooling water when air hose is connected to flush connector which allows it to push water out by venturi rather than flowing out of exhaust inlet. As air is flowing from high point to low point and does not pass through exhaust pipe on way through manifold there should be no way to get water into cylinders. Can also see how when running motor of hose through flush adapter how exhaust pressure pushes water to exhaust pipe (though does not look like it runs through manifold). Thanks again.
