I discovered I had a head gasket failure on the right side of my 1985
Evinrude 175 HP outboard. The plugs were fouled with sea water as was the
cylinders. I sprayed the cylinder bores with anti-sieze lubricant after
cleaning them, this after removing the head to get to the gasket. My
thermostat and pressure relief valve were also junk from the corrosive power
of salt. I am replacing the head gasket and the other parts. Could this
sea water have gotten past the piston rings and into the crankcase. Is
there anything else I should address because of this problem? Your concern
and comments are appreciated from this novice wrench. Russell Hermansen

Russell, the http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi forum has a
section on Johnson and Evinrude outboard problems. Lots of reading there.
I think that most people would advise you to check the other side of your
engine as well.

If salt water sat on the top of the piston, it also ran down past the ring.
Rings are not a water proof seal.

when u say anti-seize I hope u don't mean never seize, if so get that stuff
cleaned out of there before u burn it and dry it out it will turn to a
compound and wear out your rings and cylinder very quick, I herd a friend
tell me he used marvel mystery oil and blew it out the spark plug holes
without disassembly and it ran good, PS change the oil and filter a few
times ,once now before running and then run it to mix it up with the water
and try to get it all out, salt water is a killer, how long was it in there
before u noticed?
