    2016 250 pro xs won’t start

    While out Saturday after running all day from 7 to 1 pm at 1:15 after moving from a spot I idle up under and bridge and then got on plane while on plane around 50 mph something happend no loud boom or pop no alarm all day. It was like a complete lose of power. When I turn the keep over it beeps one time completing the guardian alarm and will hit one time but starter will not turn the fly wheel. It is not easy to move the fly wheel by hand so I did not try much. My lower unit was leaking from the drain screw after this problem accumulated but it will go in forward Nutruaul and reverse fine with no knocking when I spin the prop at all. I’m confused but again never been in a boat when it lets go or blows up.

    Sounds like driveshaft bearings have went bad. Not a uncommon problem.

    possibly remove gearcase first to determine where problem is upper or lower
