Problem i am having is when taking off half the time it takes off fine and the other half its acting like its bogging down. When up to speed it surges 5 to 7 mph. Bought the boat and engine new 3 years ago, If i remember right it started doing it the end of last year but not as bad. I have looked at the fuel filter it looks like its new. I pulled spark plugs they look great. I put stabil in the fuel system before winter and since then i have ran that fuel out and have put new fuel in it. Any help would be appreciated, Thanks
