Hello,
I am having troubles with my Merc 150. I have consulted others about the problem, but I want to be sure said problem is occurring.
It starts and runs fine, for the first bit. After the engine warms up to operating temperature, it starts to sputter (as if it's running on 3 cylinders), and sometimes dies. If it does die, it is near impossible to get it restarted without letting it cool down. I have been told that this may be a switchbox issue, and have attempted (with my limited electrical knowledge) to diagnose said problem, but want to be sure it is the problem before spending the money on a component I may not need. There is limited spark when the engine is hot, but it returns to normal after cooling down. We have ruled out any fuel issues, as the pump is operating fine and there is plenty of gas flowing. Any advice / test procedures you guys can give me so I can possibly diagnose the problem for good?
