There might be a couple of things you can try.First is the ski strongly trying to start and if it is (1.) carefully take out all the spark plugs from the motor put 1 inside the spark plug boot being careful put the spark plug to any part of the cylinder head carefully start the motor while doing so at the same time look for a spark of electricity coming from the spark plug if there is none then your stator might need some cleaning or replacement good luck hope it works out for you. Note you might want to make sure your ski has fuel to being that you have not start it in a while.
