OMC prop on a Mercury

[89LASER]

When running an OMC prop on a Mercury, what washer do you put behind the prop nut?

[David]

I bought a washer and a lock nut from DAH to run an SRX on my first Merc. I expect you could find what you need elsewhere but that was easy for me

The prop nut is a thin nyloc

Someone made a kit at one time... Baker Marine maybe?

The spline length and depth is different. It is easier to go from OMC to Merc than visa-versa.
