Rotax ACE 900 and 600 Engines

50% more power and 77% more torque than the ACE 600 engine. The ACE 900 engine achieves up to 23 mpg (10 L/100 km)*. And for a first in snowmobiling, it uses the Intelligent Throttle Control System (iTC) for added efficiency and functionality. Choose from three driving modes, simply by pushing a button on the console: Standard, Sport and ECO mode. Plus, Learning Key technology limits performance for novice riders.

*Data based on BRP engineering testing on GSX LE in its ECO driving mode.

Ski Doo addresses the problem. It is why they gain market share. Cat and Polaris rider for over 50 years. They just made a new customer. The ACE engines are the first step to fixing snowmobiling. Thank you BRP.

I keep having problems with fuel filter on my 600 ace engine have to keep an eye on that once it gunks up and your in the middle of no where it’s good to have a spare one for quick fix with tool kit for the gen 4 skidoo.

Hello everyone, I´m glad that there are a large number of fans and enthusiasts of the Wankel engine and 2-stroke engine, the truth is that they are good engines, but due to the increasing pollution problems are increasingly scarcer.
I have developed and patented two Hybrid Rotary Engines both 2 and 4 stroke, along with a new thermodynamic cycle "Cross cycle", that improves the cycles: Otto, Atkinson, Diesel, Miller and the recent HEHC Liquid Piston Engine.

Steve, I wish I could get 23mpg on the etec, I'm closer to 16mpg on my etec 600.... It took 2000 miles to get it up to this point too. I used to get 20mpg on my etec 600 backcountry, but the gearing/clutching on the adrenaline is much worse for economy.

Why does our 900cc one whine on the right hand side of the vehicle occasionally?

Paul Gelinas snowmobiler since 1959 same year as the introduction of the "ski-dog", got a kick out of this.

[Gabeosauki]

is it a twin like the 600 or a triple like the 1200?

[SJSTransit]

What's the weight in comparison to a 800 eTec. As far as mpg I ride a 600 eTec averaging 23mpg with what I've seen the same performance as the 900 Ace.

[prosled]

what kind of horse power? equal to a 600 in performance?

[noxkidxxx]

An ace 900 is a triple and pushes 90 hp, as Yamaha phazer is a twin 500 and pushes 80 hp. :-/

Can’t hear anything except loud noise of sound effects !

[EisblockTV]

Nice, could somebody tell me whats the name of the (Dubstep) Beat in the Background?

They should make a 700 ACE for a little more power! 2 STROKE SLEDS are unreliable GAS GUZZLERS!  Although 16MPG on a 600 etc 2STROKE isn't bad at all! I'll take the reliability and fuel economy of a 4 stroke on a SLED considering GAS PRICES are consistently around $3.50 a gallon! My Kawasaki KDX 200(2 STROKE) motorcycle gets around 58 MPG! Compared to Honda xr200R(4STROKE) 60 MPG! A little Different on WHEELS!

they need to turbo this motor and put it in a summit

[marywiebe]

i have a 500cc rotax engine with no spark at the spark plug can you help ?

[jjgebarowski]

The amount of snowmobilers is in decline because of fuel prices... If you think the average Joe can afford riding 80 miles for a $50 fill-up, you are nuts. I run an Etec 600, which I think it better than the ACE, but its more expensive too.

I miss a cable, instead of all these "modes"

[fishinghuntingak]

Easy oil filter access! Just remove whole right side, muffler, and find some small girly hands to access it!

[ThomasAX]

No, sleds don't need more electronics, people need to be smart enough to take care of the ebrake themself! If you seriously cant tell that your ebrakes on you should probably try a different sport!

Ace built for maximum torque and fuel economy, unlike yamaha's high revving motorcycle engine's, ace engines designed as a snowmobile engine, not borrowed from a motorcycle and put into a snowmobile.
