"My Yamaha 90 hp outboard 1997
"My Yamaha 90 hp outboard 1997 model loses power when it reaches normal operating temperature, the over heat buzzer sounds and the motor drops to 2000 rpm, this is normal if the engine over heats but mine is not over heating, could it be a faulty sensor or maybe the sensor has gone out of calibration,
the oil level is full
thanks"
