30hp autolube

[sande]

I have a Yamaha 30hp 2t autolube with the same problem. Start perfekt. Whene i give full gas, in gear, the engine run perfekt for few seconds and then go down to a low unstabel run. I have a feeling that some electronic limiting happens?? Whene the engine is in free gear it runs perfekt with full gas. Please help. Best regards Peter Sande. Copenhagen Denmark

Either overheating, oil tank low, or the sensors for those functions are malfunctioning. Maybe wire harness grounding out too.
