Cox Ski-Doo Silver Bullet 440 Snowmobile (1973)

By | Sep 30, 2017

What better way to enjoy winter than with some vintage vehicular fun!

Ok there’s probably a number of better ways, but today was a rare treat when my friend Bill brought up his rare Cox Ski-Doo .049 powered snow mobile up for a few laps around the driveway.

The story behind the Cox Ski-Doo is an interesting one. Back in 1973, Cox had made a deal with the Bombardier company. Bombardier made the full size version of the Ski-Doo. The deal between Cox and Bombardier would have Bombardier purchase a larger number of the Cox Ski-Doos to give away as promotional items to anyone who bought a full-size Ski-Doo. Unfortunately for Cox, the deal fell through. Cox made the mini Ski-Doo anyway, but it didn’t sell very well. Consequently, the Cox Ski-Doo is a rare find today.

Under the hood is the venerable Cox .049 powerplant. Extra large cooling head and a cooling fan molded into the clutch bell help keep the engine within operating temperatures while hidden under the snowmobile body work. This vehicle also has the pull start.

Forward propulsion is provided by the cleated drive belt, just like the real thing. Steering was possible by turing the skis left or right, allowing the snowmobile to run in easily chase-able circles.

These are some action shots I fired off while the snowmobile ran circles around my driveway:

    What a treat to actually see a Cox snowmobile runnung! Really takes me back in time. What would one of these be worth (In good condition)?

    I had a couple of these and had them running well, untill I closed the hood. I had a yellow one first and the hood problem came up, called COX etc. returned it for a silver one, same thing. I wish I would have found a way to make it run with the hood down, like drilled another hole or something, Probobly would have had it today.
    I did have a jeep first and got that running after brake in then it ran for years, I found a pair of the sand blaster slicks and they fit on the axles, that was fun.
    Thanks for the memories, Jon

    I see the slicks are on the trike, they said sand blaster on the ones I had and they caused the jeep to go much faster (body broke so didnt have that on when running), it would go across the lawn with the extra ground clearance and do wheelies when it came to a stiffer patch of grass, very agressive free wheeling experience, the crankshaft finally broke (after years) and I rebuilt it with a new crank, reed, jug and piston, then ran some more.

    Your best bet is to scour ebay. They come up fairly regularly. Good luck!
