Was new on 3/21/06. The last time i was out it ran real bad and last a lot of power and sounded bad. Took it in for the 100 service and told the about the issues. Turns out some gears have sheared off and metal thruout the engine....not good. Anyway just heard today that Yammy is replacing the engine under warranty. has anyone had anything like this happen and if so, you got any recomondations. I am a little shell shocked, but happy to get a new engine, i think.
