Evinrude 120hp VRO Clicking Sound

[marvey]

Hey guys.
There's an odd clicking sound that's coming for the upper parts on my mid 90's 120hp Evi VRO.
cant hear it at idle only when in drive. Thinking also it might be the lower unit travelling through the engine. Here's a video.... any help would be appreciated.

Stop running it !!----Do a compression test.----Post your numbers.----Check the gear oil too.

guess it's possible the wrong plugs were installed (reach is too long, hitting piston heads.) Pull plugs and look in with a flashlight for piston damage.
