Over heating???

[Chewy22]

I installed my removable snow flap and tested it out today. Engine temps averaged 20-30 degrees F cooler with the flap on and the sled never overheated once all day! Pretty excited as it makes a drastic difference in cooling on harder packed snow through the trees.

I did have to trim the stock Catalyst flap slightly. Also, because the risers on the Ski Doo flap are taller than the thickness of the Catalyst flap. I ended up making a couple of approx. 1/4" thick backer plates out a medium duty truck flap. The truck flap is a fairly stiff rubber/plastic material, and I ended up sanding it down to the desired thickness on the stationary sander.

The backer plates are then riveted in place to the Catalyst flap and help it support the Ski Doo flap extension. When the snow flap is not on the sled, it fits nicely into my tunnel bag.

Best money that I've spent on a sled in a long time!

Nicely done! This will work great in those situations it’s needed.

Thanks Chew22, this mod actually exceeded my expectations.

There is specific trail into the back country that is a "one way" in kind of deal, so you pretty much have to stay on the trail. In the past the temp would get up to 175 degrees F with the Red light on. On the same trail with the flap on, the temp gauge stayed at just one bar above the mid point all the way in. I'm sure it's possible to get it hotter if you do a lot of stopping without shutting the sled off. But it's definitely a win/win mod.

Nice touch on the flap mod, AC should have a flap they would sell one to every M sled owner...they really suffer when snow is low down low.
I did nearly the same thing on mine, haven't tried it yet!!

20-30 degrees is tremendous. Some us that have to ride in less than ideal conditions for these sleds, to get to the good stuff, def know the overheating challenges.
This is a great quick removal design. Can you share info on where you got the ski doo flap, or what it came off?

Ski Doo part number is 860202393 and it's off of Summit Expert sleds. List price is an eye opening (for a snow flap) $180, but I did an on-line search and found one for $135 with free shipping. Now I see Amazon has it for $128 from the same seller. Not sure how many they have in stock though, might become a hot item (no pun intended!

Looks nice. I think having a full flap is very helpful in marginal snow, but it's a bit of an anchor as soon as you get into deep snow. I installed Everett's kit on my sled, and it's well worth it. More often than not I don't even bother dropping the scratchers. I can't say it's night and day when I stow the flap in deep snow, but I think it makes a difference. This looks a little easier to deal with; the latches on mine aren't glove-friendly. I'm guessing the 20-30 degree drop is typical, but it could make even more difference in some conditions. Definitely a good idea for most sleds.
