Question Skidoo 600 E-TEC motor feedback wanted.

Now that people have had a chance to put some miles on the 600 E-TEC engines have you heard any good or bad things about them? Any bugs? OMC has been using this technology for a few years in outboards and no problems so I would not expect there is very many problems in a sled.

Cool E-Tec mystery

I am curious about the E-Tec as well. Am considering sno-checking one.
Had a buddy demo one for a day in the mountains and he loved it; didn't have to carry fuel, never looked at the oil, started on first pull every time, the chassis was great; climbed and side-hilled like a billygoat.

I can't get a straight answer on the horsepower. I am hearing 118 HP, the dealer is telling me 130HP which I think is BS and I checked on the Rotax website and it's hard to tell but they have an older version of a 593 E-Tec shown at 115 HP.

Anyone have any ideas?

A buddy of mine scuffed a piston in his.. low compression on one cylinder.. not sure if it's a common thing to happen to those sleds, he's the only guy i know who owns one.. I'd wait a year before buying one so that they canwork the bugs out of it..

Hey guys, saw your call for feedback and figured I'd help as much as I can. Bought an '09 Summit last year and was sceptical buying a new motor and was dissapointed when I popped a piston after about 3 kilometers on the sled. Apparantly there was a thermostat problem that caused it and after the warranty work was done I put over 3000km on the sled problem free. I didn't even snap a belt or anything. My brother had a renengade with the 800R and we found I used about half the fuel and oil, which was awsome! After the sled sat at the dealer for some insurance claim work they found an improperly sealed crankcase that was leaving a small drip. Again a quick fix and so far this year no major problems. To answer the hp question its approximately 120-122hp and with the summit gearing its got alot of snap. Apparantly you can advance the timing around 2 degrees for a little more as well. Power, speed, response, fuel and oil consumption are really quite amazing for such a small 2 stroke BUT I'm now discovering a bad flat spot or stutter at mid rpm's when you hammer on the throttle it'll literally burp 1-5 times before picking itself up. It will be going back to get looked at soon for that problem and to have the timing changed so hopefully that'll eleviate my problem. Also there is now finally an aftermarket exhaust can that accepts the O2 sensor and should put a 146" summit such as mine under the 400lb threshold and make it sound better. Hope this helps.

Another thing to add as far as bugs go. A new fuel map was introduced this year and is a free upgrade at your dealer I beleive. Talked to the owner of my dealer and my sled has been the only one with major motor work done and has so far been the only he knows of around where I live.

Same technology as BRP has been using in the Evinrude outboards for several years.

This month's Snow Tech magazine has a 3 page article on the inner workings of the E-Tec, great article.

600 etech

I've put about 650 km's on my 2010 600 renegade. So far I'm not impressed by fuel or oil consumption. May just be because of break in period, hopefully! Power is good, not as strong as my buddies polaris, but smooth power delivery. Sled handles well on trails, and really well in the powder, not that we have much this year. No problems as of yet. Will let you know if oil and fuel consumption gets any better. I figure i'm getting about 280-300 km's to a tank, but i like to use all of the 600's power. And in 650 km's Ive used about 2.5L of oil. I was told by the dealer that i would use only 2-3 L a season, and would get 350 km's to a tank playing pretty hard, not that i believed it. Definately no 130 hp! 115 sounds better!

ya man i think those sleds come mapped to run a certain way for some many hours then they change the map which burns less fuel and oil
