Evinrude 1987 140 v4 Rebuild

[nymack66]

Guys,
Below is a thought process I read on another blog strong believer in it.
"Having to rebuild a engine is fixing the symptoms of a failure, so one MUST find the reason for the failure and fix it, if not plan on fixing again"

With that said I will post the various things I find along the way some Evinrude CSI work :) if you will.

I may or may not find it or should be too concern because the baby will be built with care and love with a fine tooth comb, any future failure is mine to own, the buck stops here with me.

At the time of purchase the previous owner give me and I quote "Here is new set of plugs for the engine"
Trouble is this kind of plugs does NOT match the Evinrude plug recommend charts?
QL77YC
Funny I found on the Internet this plug matches a Mercury motor, which I saw in his yard mounted on 18' CC Wellcraft.
I also observe some scaring on the connecting rod journal on the #3 cylinder ?
Idle jets were jetted up .20 (Factory is .16) I did not check high speed as yet they should be .64 stock
