leaking water tube

[kbarefoot]

i have a 1987 sunbird with a 165hp, mercrusier engine the ford type. thanks for the help with the starter by the way. the problem i'm having is when i hook up the water to the lower unit and turn it on i have water running out of the tube on the left side at the back. it is not antifreeze and it only does it when water is turned on and running through the whole motor, is this somthing like a rubber seal back there it feels like it is please heeeeelp fishing season is upon us and i need to goooooooo. the crokers are calling my name 4hrs away in va.

Kenneth - I saw your post a couple days ago and waited for someone to respond because I'm a bit confused by your question. Could you explain a little bit more about where the water is leaking from?

Kenneth,<br /><br /> Are we talking about a 3.7L mercury motor w/ a ford cylinder head?? Sounds like you froze the heat exchanger or left the plug out. I have been succesfull at soldering them back together.

Ahuh!!!! Kenneth...you're talking about inside your boat...the heat exchanger. There are rubber gaskets on either end of the exchanger, could be leaking out of there. Or as suggested by Master Tech, drain plug is loose or missing. Here the diagram.... <br /><br /> http://www.mercruiserparts.com/Show...25.png&inbr=908&bnbr=120&bdesc=HEAT+EXCHANGER
