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...
 
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.
 
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?
