I just picked up a shadowcast 18 with a 2014 30hp tohatsu tiller. Engine seems to be running great and I'm stoked with the performance I'm getting. My problem is that the alarm has been going off and I can't figure out why. Doesn't ever happen while I'm running at high rpm's, but every time it has come on has been while idling after coming off plane, or at the dock waiting to trailer it. It's peeing fine and doesn't seem to be running hot at all. Anyone have any ideas what the problem could be, and/or how I can get it to stop???
