Looking for help for a friend's 197 with Indmar MCX. Yesterday engine check came on and sent engine to limp mode...it happened twice when he was skiing. ..once he was back in the boat it ran fine...I assumed a random event with no relation to the skiing. Tonight I went out with him to witness it myself and was surprised with the symptoms. Boat ran fine to the slalom course (about 1 mile). He got in the water and I tried to get him up 3 times and engine check/limp mode came within less than 50 yds each time. He got back in the boat and it ran fine all the way home...looks like some load related sensor but I have no clue on what to even look at. He has no capability to connect it to a computer for diagnosis....any thoughts at all?
