"I have a dana model 80 outdrive. There are no parts outside the bell housing to disengage the clutch inside the bell housing. No clutch "arm", no pivot parts (although there is a mounting hole with a bolt) no cylinder to move the arm if it was there. This is the way the boat came to me. The cable/cylinder from the front is there. The boat shifts OK. Do I need to get this fixed and if so where can I get a new arm/parts/picture of what this is supposed to look like. I presently have the pivot housing off the boat while doing a transom repair so I have access to everything."
