How bad is it.

[Brian Hall]

I have a 1973 Evinrude 85horse. I did a decarb a few weeks ago and decided to go out and check the compression and change the plugs. They came back 120, 123, 125, 105.<br /><br />The plug that came from the 105 was very clean and seemed to have some water droplets on it. I am assuming that water is getting in from a gasket somewhere.<br /><br />How bad is it going to get if I keep running it like this and how much will it be to fix it? Can I do this myself?<br /><br />Thanks for the help.

Re: How bad is it.

Howdy Tx....Ya' know any hombre's down there that go by JB? Just had ta' throw that in.<br /><br />Well....water can be gettin' into the cylinder from a couple places. One....the head gasket could have a leak and two...the exhaust cover gasket could have a leak. But seein' as how the compression is a tad low on that cylinder, the head gasket is the place I'd head first. Ain't no big deal to change. Just gotta have a torque wrench to do the job right. Head gasket will set ya' back about $30 American money. I wouldn't run it with a water leak. Does nasty things to the walls of the cylinder. <br /><br />Hope we've helped a little. Keep us posted.
