I have been working on a 1984 50 hp force for quite some time. When I first purchased the motor it would start fine other than needing a carb job. One weekend I went out to start it and when I turned the key nothing happend and such has been the story for many months. I have replaced the startor motor, starter selonoide, rectifier, neutral safety switch, and finally the ignition switch with the same result each time. I have tried a few different batteries changed connections on all wires. I cannot think of anything else to change if anyone has any ideas they would be very much appreciated. other than basic mechanical skills I have no idea what im doing with this motor, this is my first one, thankyou.
