Water in #6cyl.

[tkmichael11]

While tearing apart the starboard side of my 228 merc. (to replace the starter) I pulled the spark plugs and #6 was full of water. Compression is good and the boat runs good. Before the starter went out, she was doing about 32mph at about 3400rpm. It idles good and take a bit of time to get on plane, but once its there, she is very smooth!

Where could this water be coming from and why only the #6cyl?

Ayuh,....

Probably the Starboard Riser, or it's Gasket is Shot,+ #6 exhaust valve was open....

Thanks. I searched some of the threads in this forum and noticed the consensus for water in cylinders was probably due to a gasket failure either betweeen the riser and manifold or the manifold and the head.

I re-used the old gaskets, when putting everything back together, and I'm hoping that is the problem and nothing more serious.

The info is appreciated!

Nope,.....

Those gaskets see No Water,.... Just exhaust Gases.....
