hey guys this may seem like a dumb question but i have a 3.7l mercruiser 1988 motor and i cant seem to see whether or not it has a kill switch on it.. I know a little bit about outboard motors but very little on inboards i know all out boards have them but i was just wondering. also I am having a voltage drop when i am trying to start my motor it goes from 12v down to 10v i was thinking it could be the coil maybe? other than that i am lost.. any help would be much appreciated thanks guys
