I have a 2004 Yamaha 150 TXRC outboard motor on my boat. My motor was running irregularly and sputtering while in gear so I decided to flush out my fuel lines and clean out the carbs. I noticed afterwards that the motor started quicker and idled stronger. I decided to take the boat out this morning for a victory ride and the motor not only stalled, but it also would not throttle. While this was happening, I noticed that my gauges (voltage meter, fuel, etc.) would not register. I turned the motor off and waited a minute. Feeling frustrated, I decided to try and restart the motor. The gauges worked fine and the motor ran strong and throttled normally.
Other than contaminated fuel, what would be another reason this is happening?
