I have a 2001 gt40 air nautique. recently started to sound like a misfire. engine feels sluggish and has trouble accelerating past about 25 or 30 mph. it does not have that power that I know the engine normally has. I checked filter in fcc and was good. no water in fcc either. checked the plugs and they looked good. cables and plugs were changed maybe 150 hours ago. motor has about 620 hours on it. very well kept by previous owner. I bought it last march and it has been great until now. i tried Seafoam a while back when it was a bit sluggish and that kinda resolved it but was not perfect. any thoughts??
