I have a 1969 Mercury Merc 350 35 H.P. outboard that I'm trying to find a new key switch for online. I took the control box apart today to see if I could find a part number and all I could find was a little white sticker on the side that had 130 D51015 wrote on it. I've tried to find this online but haven't had any luck. It's a 6 wire switch with three positions off, run and start. Does anybody know what I need?
