Hello,<br /><br />As I have found everybody here so helpful in the past getting me thus far .... I have hit another seems to be road block ! <br /><br />I have a Mercury 65HP O/B model #2448761<br /><br />Anyways I just replaced the gaskets/impellor on this thing ...finally got the time to put it back together and see if it would fire up and **** some water out the back... Well here is what I got.<br /><br />I ran it for a short bit...keeping my hand on the motor to make sure of no overheating.... and I am seeing water dripping where looks to be like the bottom of the #1 spark plug !! I don't see anything coming out the top two holes as far as water, but on the bottom there is what looks like two vents right above the trim tab ? and water is going through there. When I shut the engine off I could hear a hissing noise coming from the number 1 cylinder. Help me out here guys ...what the heck is going on ?<br /><br />My thoughts ... of a possibility ...<br />When putting it back together I noticed that it was particularly hard to get the lower unit back in because of the water pumps pipe, which was a copper pipe, moved around a little...seemed like the seal was good at the base because I blew through the end of the tube and didn't get any leaking air. Now if I missed the hole (no pun intended) w/ the pipe, would the water be going up through the exhaust and into the number 1 cylinder. <br /><br />Sorry for the long post, but to get the best help I have noticed that the more info that you have the better.<br /><br />thanks

Some mercs have water gallery cover where the<br /> spark plugs are.Could simply be a water leak where it meets the plug.

Re: Water coming out of #1 cylinder !!

ok .... thanks.<br /><br />do you know if older mercs have thermostats and where they would be located ? I am cautious to run the engine very long at all when I don't see any water coming out the back at the top .... do I run it w/ my hand on the engine and if it gets to hot to the touch take it off ? Or am I taking too much of a risk here ?<br /><br />I guess since there is water coming out by one of the spark plugs then that is a good sign in a way.<br /><br />I will have to investigate further for as far as where the water is coming from .<br /><br />thanks
