    Default F115 4 Stroke wont run at WOT...

    Ran my boat yesterday for the first time this year and it idles fine, take off is fine, and mid-range is fine. When I pushed it up to wide open throttle it acts like it's missing or starving for fuel. I service the motor annually and run the Yamaha Fuel Additive but can't remember if I added any Stabil last time I put fuel in it.

    Can anyone point me in the right direction? Thanks in advance...

    I forgot to mention it's a 2005 motor and has never had any fuel filters or water/fuel seperator cleaned.

    It is time to service the fuel system. You are brave to run your engine that long with out servicing the fuel system. Once you do this (annual) service take it for a ride. If the problem continues let us know. Do the water pump too.

    You forgot to mention the Gasoline.NO ETHANOL! Drain all your gasoline out of your tank.Put it in your Auto.

    My 06 f115 is the same. The trouble started last year and is back but affects most of the rev range, also smelling rich. I haven't serviced the fuel system but did clean the injectors with an ultrasonic cleaner. Are you asying the filters may be clogged?
