I have a Wizard WH 6, 5 hp that needs the red neutral knob. Anyone got one for sale, or know where I can get one? Thanks, David

I just had to buy the same thing, and they are the exact one's Mercury used on the Mark 6s. They are available at:

Unlike the originals, which were plastic on mine, the ones sold above are aluminum.
