Just took our new 2013 Moomba LSV out the other day for the 2nd time. I noticed the "check engine" light came on after we had it out for a couple of hours. Boat seemed to be running fine despite the light coming on. Only thing I did that could cause the light to come on is I left the blower on for most of the ride before realizing it was still on. The stereo turned off on its own while I was driving the boat. I switched over to the 2nd battery and the stereo worked fine. Never had any problems starting the engine back up after the stereo went off, even when using the 1st battery. All gauges were normal on the dash, including battery voltage, the entire time. My question is this: Would the battery losing voltage like that trigger the "check engine" light to come on? I talked to the dealer and they seemed to think that is likely what caused the "check engine" light to come on. Anybody else experience anything like this before?
