After going slow (no wake) for a while my warning horn goes off. When I shift it back in neutral and put it back in gear it goes back off. It did the same thing a couple times last spring when I took it out of storage but ran fine the rest of the season. (Didn't have to travel long areas of no wake after spring). Also when traveling slow the motor also seems to smoke quite a bit more, could the plugs be loading causing the alarm to go off or something else? I have a kicker so I don't troll at all with the big motor. The alarm is the constant one not the intermediate beeps and I do not have the smartcraft gauges. I've called to bring it in but was wondering if anyone had any opinions on this. Thanks

Another forum. The end result was interesting. Bad sensor.

seems as though the impeller's can be the problem as well.
