SO saturday the sync and low idle stopped working. After a four hr run they both started to work . I looked for loose connections under dash and on the motor . I found nothing . Yesterday same thing ... after long run they start to work again. Anyone have a clue ? Makes sense if one item doesn't work none do. But I don't know what to start looking for . It sounds like something is loose. ( cant be water as boat wasn't washed and it hasn't rained in weeks . ) Also everything else is fine . All readings on smart craft are there etc . I tried starting motors in a different order . NADA

Thanks guys

Rob
