I was recently given an old 50 HP Merc motor. I was told the motor was in good running condition when it was abandoned several years ago. The owner passed away and a neighbor "rescued" it. It is dried out to the point of being hard to turn with the plugs out. What I would like to know is what to do to get it to the point of getting a decent compression test. The propeller shaft is non-marked from fishing line and the major components look good except the wiring (of course). Any ideas.

Thanks for the quick response, jiimbo, and the great link. That should keep me busy for quite awhile.
