My brother has a Yamaha 60HP FETO L (a 6H2 L, serial no 458506) outboard
and it has developed a problem whereby he was out in his boat a while ago fishing and switched the engine off for a while, about half an hour. When he restarted it it would not rev above 2000 rpm. It would happily rev to 4600 prior to this. I know nothing about outboard engines but have rebuilt a few car engines and it has been my hobby for years. He says the buzzer is not going off (the overheat alarm?) and the oil feeder system is functioning correctly. He thinks there is a problem with a contriol circuit which reduces the revs if the engine overheats. It isn't overheating though. One thing that has come to mind is I believe the overheat sensor in the head works like a switch and grounds the signal so it could be something as simple as the sensor going defective and shorting to earth. Any suggestions? Cheers Barry Chapman |

Maybe oil sender sensor? Or a loose connection, put OB in " limp-in Mode"
