Looking for input. Pontoon with merc 115 4 stoke has abruptly started to idle rough and bogs on take off. It smooths out then bogs down again. It continues the same symptoms for 10 plus minutes before seemingly working itself out then runs fine. If I slow to an idle or stop, I have to go through the same process again of bogging and smoothing out for a few minutes before it seemingly works itself out.
I am am very new to the boating world and know very little about boat motors. Any help would be greatly appreciated.
