Proper Compression Info

[Mark Overfelt]

Could someone please tell me how to properly check the engine compression on a 1979 Mariner 70 HP outboard, or direct me to a website or prior post on this topic. Thanks to any and all for your help. Mark "BIG RED" O.

There are some good posts listed here:<br /><br /> http://www.outboardrepairs.com/compression/ <br /><br />Several of them outline the process well.
