    Default Circulation problems

    Hi, I intended to use my 92 Moomba on vacation next week so I figured the prudent thing to do would be to fire it up here at home. So I hooked up a water hose to the intake hose and when I turned on the water, nothing happened at first. Then the hose blew off. I started thinking of reasons why water wouldn't circulate through the engine and I started with the water pump. I took it off and inspected it and found nothing out of the ordinary. Next in line was the thermostat, so I took it out and replaced it. I can start the boat, and it seems to run just fine but as soon as I shut the engine off the pressure builds up and blows the hose off again. Shouldn't the water run through the engine even if it is not running? Any thoughts?
    Thanks,
    Bill

    Do you get water coming out of the exhaust flappers with the engine running? If so, you are good, I reckon. My engine does not allow the water through unless it is running. I think you are fine.
