I have a 1999 Yamaha F50 and it gets up and planes out good with a light load. With a heavier load it doesn't seem to quite have the power to get up on step. I have another identical unit and it has no problem with the same load. It almost seems like it is intermitently running on 3 cylinders, it idles perfect and runs great at low speeds. I have flushed the carb's changed plugs, and this does not help.
Any help would be appreciated.
Thanks.
