Is this motor a lost cause or will I get it running? I check out this old Mercury 2 stroke outboard motor to see if it has what it needs to run. I recently purchased an old Mercury 7.5 hp 2 stroke outboard engine from 1971 that had not run in years. Will this engine run? Can I get this old 2 stroke outboard running again? I cover the process I use to evaluate an old engine and the tests I do to see if it has the potential to run and what to check before you start spending money on parts. Testing an outboard motor isn't hard and you only need a few special tools to do the basic tests to see if it will run.

In this video I show you how to do a compression test, how to use a spark tester and step-by-step process of troubleshooting and evaluating an old 2 stroke outboard motor to see if it will run. I show you how to check for spark on an outboard engine. I show you how to use a compression test gauge and what the results mean when checking an outboard motor. I show my process for troubleshooting fuel issues and how to follow a logical path to identifying fuel and carb issues on older outboard motors.
