Hello,
I want to do a quick compression test on a 2001 F80 outboard. I know a leak down test is required for an acurate test. I am changing the spark plugs and engine anodes so I would like to do a quick compression test.
What needs to be done to do this? I have never done a compression test on a 4 stroke outboard engine. It is a carburated engine with no EMM.
Do I need to ground the plug wire?
