I just bought a 69 Evinrude 85hp that is getting water in the left upper cylinder. It ran funny was having problems accelerating and the spark plug was clean as a whistle. I changed head gasket, did a final torque of 20 ft. lbs. I ran it and then retorqued, took it out saturday and it runs great plugs looked good and then water in cylinder again, but now it is in both on that bank. I checked torque when I got back Saturday and the top two bolts were loose. When hooked up to hose and running should there be water coming out of prop with exhaust? I disconnected hose from cylinder head to see if water is flowing and it is. Can water get into cylinder from any other way besides head gasket on this . Any ideas? I am stumped and wife is getting impatient. lol Thanks for any help, I really appreciate it.

Checked the compression today, the lowest as 70 and the highest was 75. I am getting water now on three plugs. So I am thinking maybe water in gas??? I doubt it, I would never get that lucky. I stopped at the local boat guy today and he acted like it wasnt really possible for water to come in through the exhaust. Is he right?
Well I ot the exhaust cover off and there was definately water leaking there. There was some white scale build up and the lower right corner with the hole for water had a leak so I think I found my problem. How hard would this motor be to rebuild? Is there a lot involved?
Well two bolts broke off trie pb blaster for 3 days and heat, still would not budge so I drilled them out, the one did not drill the best cause my small bit broke off. Will some kind of silicone hold up on these gaskets to help seal it?
I used that high temp copper silicone stuff on the exhaust cover, will that hurt anthing? After drilling the second hole I ended up with not much left to seal aroung one of the bolt holes.
Got her back together tonight, fired it up. Let it run, checked plugs still water Now what?? Good anchor? I am sick of it.I don't know what to check or do next. I did notice for the first time water came out through the prop with the exhaust. The one head gets noticibly hotter than the other. I checked with my ir termometer 127 and 180 on the other. That is too hot correct? Please someone chime in.
Dude Im Sorry About Your Luck Just Out Of Couriosity Is It A Closed Deck Or Open Deck In Other Words Does Water Go Around By Your Cylinders If So You Could Have A Small Hole Thats Letting Water Into Your Cylinder(s).
There is water jackets around the cylinder walls if that is what you are asking. Compression was lower but all the same, the motor runs fairly smooth just water on the plugs
Today I started it again and one of the lower cylinders is getting lots of water so I pulled the head to look and it was filled with white foam and then I shined my light into exhaust holes and it is still leaking in the exhaust baffle So I guess it will come off again. There was a part of the baffle that was ate away and pitted, this part was covered with a white powdery substance so is it possible there is holes in the baffle and if so can they be welded successfully.
I'm guessing that you are talking about the inner exhaust cover, and if it's eaten away it's probably not the stainless steel one. If it's aluminum and already corroded, then it needs replacing. How to get a replacement is another question, since it's no longer available on the Evinrude site.
Got everything sealed up and replaced but it is not firing on cyl 3. It has plenty of spark, the plug is clean though like possibly more water, again. And now the stinking starter decided to go out.
Yea I know, it just sucks I am too gullible, I got suckered into another bad outboard. The lower unit is good, I just want to enjoy my boat. But am thinking about selling it. If possible I want to get it running. Does anyone have any pics of spark plugs for different conditions, just so I know I am right with my diagnosis. I have this outboard on a 1970 15 ft mfg gypsy open bow. I really like the boat caus it is stable, especially with the kids .
