Reply To: Johnson 6 hp motor not pumping water from exhaust

OK, alot of info in your post, so I want to take time to make sure I understand…

First, you state that no water (or even spray) comes out of the exhaust relief port, correct?  With everything assembled while running, is the engine actually overheating?

You stated that with the thermostat cover removed, water does flow out of the top of the cylinder head while running.

It is your next statement that needs clarification though.  When you dump colored water down into the cylinder head, does it pour out of the exhaust relief??  Or, does it simply disappear down inside the exhaust housing?

Is this engine used in fresh or salt water?

I have a “guess” as to what is going on, but will withold it until I’m sure I understand everything you have said.
