The new snowmobile engines don't do that. Fuel injection is not subject to
such things - and if it does see the temp headed for trouble, it'll
throttle back - not die completely. My new Polaris Fusion 900 snowmobile
(
http://www.polarisindustries.com/en-...nce/900Fusion/ )
has an engine that weighs less than a Rotax 582, puts out 150 hp, and is
fuel injected by a mature reliable design. It will also do 135 mph on
Harding lake from now 'till the spring thaw!

The only thing stopping me from ripping it out of the snowmobile and
mounting it on my kitfox clone is money, and a strong paternal feeling for
the snowbound F-16 fighter it's in now ;^}

yeah, i saw some of those. about the same price as an ultralight kit w/o
motor, or sometimes with.

if I had the choice between a snomobile and an ultralight, i'd go fly. right
now neigther option is available yet (YET!) so all i can do is speculate and
window shop.
