I have a mercuy 150 hp EFI. When I go from using my 10 hp trolling motor, back to using my 150. I raise my trolling motor and lower my 150 back into the water. The 150 starts OK but when I give it gas it stutters an coughs unless I very slowly give it gas until it gets going then its fine. This just started happening. Its like you started from a dead cold start. Any suggestions ? Thanks
