Re: Can you run a Merc propeller on an OMC King Cobra?
 

You press out the Merc hub and press in an OMC.. Not rocket science here guys, hell I've done it to a set of props just to try em over the weekend, and had Merc hubs pressed back in the following week..

Yes.

Another option is props made for OMCs.

I like the Rapture series stainless 3 blade.
I use 14.25 by 21 pitch on twin small blocks with cobra 800 drives.

Beware... some "king cobra" labled cobras are not "kings."
