    Default Water Pump for 1978 - 150 Mercury Outboard

    How long should it take for water to start pumping out.

    I bought an old boat and motor and got the engine running but noticed that water did not come out. I shut it down right away, afraid I might damage the water pump, which may be already shot. It was on less then 30 seconds before I shut it down. Should I have run it longer?

    I was told that the motor was run last year.

    Of course I had the water coming into the intake with a water ears.
