I was on the water all morning with no issues and when it was time to head back to the dock my outboard would not accelerate. It turned on just fine and did not stall when put into gear but once I tried to accelerate it would only move at a slow pace. I knew this would take forever to get back to the dock so I decided to push in the key choke to see what would happen and that did the trick. When I would hold the key choke pushed in it would accelerate at full speed but one I released it , it would slow down again to just above and idle. Any help would be very appreciated!
