Aaahhh, the loss of starter problem.
That is really no big deal all you need is some rope and know how to wrap it around the prop dome.
Best done on snow with at least one Eskimo to give it the first little rotation and let the Ski Doo do the rest.
If all you keeners are interested do you want me to tell you how I started a Beech 18 on floats with a rope one time when I was all by my self on a northern Quebec lake?
