    I have a 140 h.p. mercruiser about 1985 model, my first i/o and today it ran hot almost immediately. How can I tell if I need a water pump or an impellor? Is there a way to troubleshoot this problem and if so I would almost kill for this info. I took our kids out to the lake today and had to literally listen to crying all the way home. This way only our second time out in the boat, just bought it. Thanks for any help, Billy:sad2:

    Should be a pee hole thats shooting water out of the engine as it runs.If it's not you need a new impeller for the water pump.Do not run the engine without this water pump running could spell major disaster.Thats my guess and im sticking to it.
