Flywheel Re-install

[Berdink]

I wanted to make sure I'm going to reinstall the flywheel correctly.
.
I read some threads about lapping, but I understood that to only be required when trying to pair up a new flywheel to the existing crankshaft.
.
The OMC Manual just says to clean it with their product. Others suggest acetone. The purpose is to remove any grease, oils, dirt.
Acetone because it flashes/dries off quickly..
.
How about this key - does it look okay?

Oh, and yes, I understand the key isn't what keeps the flywheel from spinning on the shaft. It's the binding of the taper of the shaft along the correct torque value.
So the reason for making sure no oils, etc, between the mating surfaces.

It seems that you already know that the factory flywheel nut torque is what keeps the key from shearing. If you do not know the precise value, one of the Johnnyrude experts on this forum will know the answer. Post year and HP.

Thanks

It's 105 foot pounds for torque.
I just wanted to make sure I wasn't missing anything and if the key looks good to others.

I cleaned both the shaft and hole in the flywheel with acetone. Let it dry and then re-installed the flywheel - making sure the key stayed lined up with the groove in the hole in the flywheel.
I then used a recommended sealer on the threads for the flywheel nut.
Tightened down in stages until I reached 105 foot pounds.
I then verified the location of the mark for TDC on the flywheel lined up with the pointer when I was at true TDC.
.
Now back to my setting of the timing thread.

Thanks.
