Hi, just curious where the exit is for the exhaust flush port on 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.

Think I received the answer "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." Thus if flush through port then flows out of this intake and dribbles out through pump below (which means need to dry and oil that area afterwards).
