Yamaha 115 SHO 2016 under 200 hrs.
Engine has been flawless until today. Always use non ethanol gas ,ring free, and put Stabil in fuel. Started across lake engine running fine after about 1/4 mi felt a sputter and rpm loss, engine continued to sputter ran very erratic, thought maybe a bit of water could have got in fuel and I could run it out. Ran boat about 5-10 more minutes no change in the sputtering type running also would not go over 5000 rpms. idles ok, good water pump output, fuel bulb is tight, water seperator filter new about 10 hrs ago, no alarms sounded. I am a fanatic about maintenance, oil changes etc. Any suggestions appreciated. Ron Navyman
