Hello all. I need to replace my shift interrupt switch and the other one that it’s connected to. I have been searching for awhile and can’t seem to find anything on it. No part number or anything. I was told by a marina that they don’t make them anymore for the year of my motor and would have to get a rebuild kit. I have a 1989 mercruiser 3.0. Anyone have any suggestions or part numbers for any of the things I’m looking for. Thanks in advance
