It fell off when I took the foot off of the upper... it's a mercury alpha 2 I/o. I can't find it in the exploded view diagram for either the upper or the foot.

Or did it fall out when I took the shift lever out? I can't remember, but I do remember that it fell out when I was taking the outdrive apart for routine inspection/maintenance.

Is that the pin for the exhaust shutter? Guessing here.

Scratch my idea. No clue now. Been a long time since I've been in one. Is it broken off on the left end? Looks worn and broken there. Some of the other guys can probably help more than me.

Looks like the exhaust shutter pivot pin. What engine and year we working on here?

It does look worn and broken on one end and worn again on the shaft...

I think you are right, well worn exhaust shutter pin.

Now, where is the shutter? Still stuck in the exhaust passages?
