Woodruff key part number

**wildnphx** · 06-07-2017, 10:27 AM

I looked high and low but cant seem to find part number for the Woodruff key for a Merc 200 EFI 1999. The one that goes on the top of the crank that the flywheel goes on. The parts diagrams don't show it or I'm blind... Anyone have that part number or happen to have an extra laying around? Trying to get this back together before my daughter comes home for leave from the Army so we can enjoy the water a little....

Sorry it is the key that sits on the crankshaft that goes into the Flywheel.... I'll edit the original post to be more clear

Hmmm I was pretty sure there was a key on there, I will look at the other powerhead when I remove it to ensure. Damn it sucks getting old and just trying to ensure I am not forgetting **** when I put this damn motor back together. Found one of the pistons no longer had the pin to keep the rings in place but it looks like I spotted it before any damaged occurred thank God.

did you find the pin or where it may have been(cyl. head)?

Number 6 in the diagram is what I need but this one shows it is for a 1999 200DFI and mine is a EFI but it is probably same part I would guess but I would rather be sure then guess.... I will check the crank part number and see if it matches my crank part number.
