Well, its been a year now and my 115 carb motor has run pretty good no complaints up until last weekend. 2 weekends ago motor ran great last weekend it would die as soon as I gave it full throttle to get on plane. In June I changed the plugs, 10 micron fuel / water seperator, greased all fittings and changed out lower unit oil. June, July ran great no issues. Last weekend after the problem, I changed the plugs again, 10 micron filter and pulled the prop, went out again this am, and the same issue. The gas is only about 4 weeks old and is the same tank of gas that ran fine 2 weekends ago, i use stabel green and seafoam in every tank. I took it over to local yamaha shop this am and left her. I am waiting on a callback, they did state that fuel related issues are not covered by the YES warranty.
also this motor burns up plugs every 3 months or so... that cannot be normal..
any thoughts....
thanks brian
