Comments about Sierra Mercury Ignition Switch (control box):
Works good, a lot better than my original wore out one from 87'. My old one I could get to turn the ignition to a middle setting that would run the boat but keep the warning alarm from turning on. Not a good thing. my new one keeps me from doing that so that I don't over heat the motor.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
