I took my boat out and when I go full troddle, my boat die. After a few minutes when I try to start it up again, it would start. But when I go full troddle it die again. I have a push starter or I can start it manual by pulling the cord. Finally, when I do get my boat to run it would run rough and a few minutes it would die again. This problem has happen serval times. But this has never happen before. I did notice that some smoke was coming from the engine, but this was only for a short period of time. Also the water from the upper unit was coming out in a mist spray if this would help. I checked all the basic for any possible reason why my boat keep quiting on me. I turn the gas gage on rich and then I set it on lean if this would help. Again, What could cause my boat to keep dying in me.
