thanks now my engine stutters on acceleration. When using hi test + sea foam for the first tank it ran fine. Once on camp gas, problem began. Adding sea foam seemed to help a bit. Engine will also stutter when running at 30 mph. Once warm, engine runs well at all speeds. Engine also starts well and idles fine. The one time I could pump bulb while accelerating, no hesitation but that I could only do once. same thing last year. I use the boat once a year for a week last two years. Fuel starvation? Air/fuel mixture? How do I tell and fix? Thanks

Ok it looks like blocked jets in the carbs. Ideally get a repair kit and get the carbs rebuilt. To do so, remove the carbs and open the bowls. Remove all rubber parts float and needle and soak in carb cleaner for a couple of hours. Then blow well with compressed air and reassemble the new kit. Replace everything back and it should be ok.
