Yamaha 9.9 four stroke

Recommended Posts

I have a Yamaha 9.9 four stroke for a kicker it runs great for the better part of the day then all of a sudden starts to sputter and quits after I get it restarted it seems to be running on one cylinder!  Anyone experience this issue and if so what was your fix?

Check the fuel line fitting where it connects to motor- the o rings can fail so it sucks air.  It is piece I have replaced.  Look at primer bulb and fuel line especially if you have used fuel with ethanol.  If those items check out- might have to clean carb.
