    Ruddermaster sending units/calibration boxes

    I have two that have never been used. Still in the boxes from Raritan. Appear to be slightly different vintages. One is around year 2000, not sure about the other. One has the actuator rod. Will sell one or both. One for $100, two for $150.

    I've tested these and they work fine. They still have the "Remove screw after installation" tags on them. Price drop to $100 for both.

    Price drop, best offer or they're going in the trash.

    Re: Ruddermaster sending units/calibration boxes

    Good morning! Are these the ones most/all Hatteras use? I have a 58LRC, and would buy these if they're the same. I'll take a look next time I'm at the boat (tomorrow). Do you know of these are standard Hat rudder indicators?

    They were pretty common years back. Here's a link to what the head unit looks like.

    There were a few different displays. My fav was the ole MK4.
