This motor is driving me crazy! This thing starts fine, engage it in gear it will only run at no wake speed. Give it full throttle and it poohs down and dies. Sometimes it will run perfect but it stranded me this past weekend. I had it in the shop and the tech said it had water in the tank. He replaced the old tanks, fuel filter, and plugs. As usual it ran great for an hour and then began again. Since then, I rebuilt the carburetor but this didn't help. Somebody help, please.
