looking for any pointers on solving my issue. Last Saturday I put in reservation gas. Then the boat would stall out while trolling. When I picked up a moved I realized the boat would only go 7 mph not 30. I suspected fouled plugs. Changed them and ran well tol fouled again. Next day I removed all gas. And changed the plugs .was running back to normal. Fast forward to yesterday and she was running rough again. Changed plugs. Ran seafoam though a gallon of gas. Sprayed carb cleaner in carbs. One plug seems to foul out more then others so I concentrated on that carb. Took it off. Cleaned it and put it back together. I did not pull out the needle cause I didn't have a replacement yet in case I lost a piece. Still running bad. I have spark at all three plugs. Sounds like too much gas or maybe air in the line somewhere. But why did it run good sunday but not today. Uhh
