I've gotten 3 different answers on what part number is appropriate for my gimbal bearing. I'm very confused. First they said I need an 18-2100, then I called back to confirm an they said I need a 18-21005. Then I called somewhere else and they told me there is not aftermarket part that will fit my boat and I need a 30-879194A01 (and I didn't like that answer because that is WAY more expensive :facepalm:. But either way, I need to find the RIGHT part. I am trying to us the link DonS provided me earlier but can't figure out what category a gimbal bearing would even be under!
