Anybody have a link to a tools store for a compression tester that has the right attachments to fit the lower cylinders on a Merc 850?<br /><br />Thanks, Chuck

SeaKaye, I bought a standard straight push-on compression tester, removed the probe from the gauge, and installed a brass 90 degree elbow on the gauge and reinstalled the probe. It will just fit your bottom cylinder.
