Hi all,
I have a 02 Merc 115 4-stroke efi that shutters and has a loss of power when I try to get on plane. After about five minutes or so of running it, it seems to fix itself. It will then run fine untill I turn it off. If I start it again it will do it for maybe 30 sec then it will fix itself. I tested the compression and spark and all ok. I have changed the thermostat since it was stuck open. I tested the thermo-sensor and its ok. I have hooked it up to a portable tank with fresh fuel and no change. I took apart the VST and cleaned it. It was clean anyway. No change. I cleaned the injectors with merc Power Tune, no change. I keep thinking its a sensor since it fixes itself, but I have pulled all I can and everything seems ok. Anyone have any ideas where to go from here?
Thanks,
Mike
