Water In Cylinder

[Chance1989]

Hey guys, I seem to be having the same issue with my 1981 johnson 25hp. I'm getting enough water in both cylinders to get the plugs wet, and make it run very poorly at idle. I have done a compression test with results showing about 105-110 each cylinder. I've replaced the head gasket head water jacket gasket and thermostat, as well as the exhaust gaskets. IM STILL GETTING WATER. I ran it for a bit to make sure it wasn't just residual, but it's about the same amount on the plugs everytime I pull them out. I'm in desperate need of any advise or direction. Thanks

Hey Guys, I'm currently having the same issue on my 1981 Johnson 25. It seems to be getting water in both cylinders, causing it to run very rough or not at all at low idle. Within the last week, I have replaced the head gasket, head water jacket gasket, thermostat, and both exhaust gaskets with no improvement. Also, I have done a compression test with decent results, about 105 in each cylinder. Not exactly sure where to look next. I was told maybe the lower crank seal. I was also wondering if there is water towards the back of the engine (around the reeds) that it could be entering in. Any help would be much appreciated. Thanks

chance 1988....you have a separate issue to resolve … open up a new topic so as not to get this topic mingled with yours

Thanks for the reply!. Okay, I will try that when I get out of work. Also, Someone else had mentioned lower crank seal... could this be the culprit by any chance?

For bottom plug but i doubt itd affect the top cylinder. Even the bottom wouldnt suck that much water in.
How do you know its water? If its getting both of the plugs wet i doubt itd idle at all.
Try putting a match to it, perhaps its excess fuel from another cause.
If you a getting water in there the whole thing turns milky and gooey pretty quickly

Most outboards have a " recirculating system " for oil that pumps from bottom cylinder to top of engine.----It pumps water too.

im just not sure if this 25hp would have that, thats all

oh how advanced!
Will be keen to hear what the problem ends up being, at least one of them should hopefully persist at it

You've got a funny attitude, like you have a chip on your shoulder.
Dutch or French i thus presume.

I had the exact same problem. Turns out it was the inner reed plate gasket.

Assume water in fuel tank has been ruled out.
