I'm in the final stages of restoring a 1962 13 whaler that came with a 1982 35hp johnson outboard that hadn't been run in 6 years.I squirted some fogging oil in the cylinders let it sit for a couple of days then hooked it up to a battery and cranked it a few times with the plugs out then did a compression check.Most repair manuals will tell you the amount of compression isn't as near as important than if they are within 10% of each other.Mine checked out just fine.

I had to rebuild the carb and fuel pump and hopefully will be starting it up soon.I also changed the lower unit oil which was really black and smelly.
