I am having a very strange issue with my Johnson Outboard -- It does not happen every time just occasionally. There seems to be no exact trigger to make the problem re-occur. Initially I was having problems with the Tilt and Ignition on the motor. If you got it to fail, the tilt would not work and the starter would not turn over -- you can hear both trying to work it just seems as thought they do not have enough power to function. If I disconnect the power from the battery and reconnect it a few seconds later the motor starts right up and the trim works fine. I replaced the starter battery and know that it is fully charged so this is not my problem. Then, I was out on Friday running around 4700 RPM cruising and the Water Temp alarm sounded and the motor stalled like it was missing really bad. I shut it down, started the engine again to check the water coming out which was cool. Once I turned the key off a few seconds and started the engine again the alarm was off and the motor ran great as long as I kept it around 4000 RPM. If I ran more than 5 minutes above that level it seemed to foul out again. These issues really messed up what would have been a nice fishing trip.
I need some help isolating the problem -- I believe it is electrical and may be related to a relay in the motor. When I got home I disconnected all the other devices on my boat besides the motor and can still get the issue to occur. I pulled the 2 trim relay switches and this stops the trim from operating but has no effect on the starter. I disconnected another device which stopped the started but had no impact on the trim. Has anyone experienced something of this nature or can someone give me a few places to start looking. I really think all the issues are effected by the same component -- none seem to occur unless the other is happening.
Thanks in advance for all your help!
