I have a stalling 2001 YAMAHA F115 four-stroke. It stalls as the throttle is applied just after you have put in gear. Also stalls when you come down in RPM when approaching the dock. I saw a similar forum discussion at http://www.yamahaoutboardparts.com/f...0-th15195.html between users High Sierra and rodbolt17. I am a reasonably proficient mechanic, (i.e. NOT mechanically challenged) but I do not have a great deal of experience with outboards. Could this be related to a fuel filter or other fuel issue? I have not replaced the fuel filter in a few years.
