My kicker will not die! It's a 1999 Merc 9.9 EL 4 stroke, newly mounted on this boat with Merc controls. Starts, runs and shifts great but won't shut off by either key or kill switch. Key-mounted choke works fine, makes it bog down and splutter but won't kill it; even removing a plug lead isn't enough, you have to yank them both. There is some kind of incompatibility with my controls, the male plug from the controls has 8 pins and physically fits the socket coming from the engine, but the latter has no conductor where pin 3 goes, just a bare hole in the plastic socket base. The controls are the older blue stripe style, no tilt/trim switch. Either the control unit or the harness that goes into the engine are incorrect for this engine - neither were supplied with the engine and were sourced by me online. Anyone care to take a stab at which one is the culprit?
