E tec life span

I know it is really early in the game to be discussing this, but has anybody heard anything about the possible life of the 600 e tec. I am thinking with how well the computer moniters everything they may have a longer life span than a standard 2 stroke, but I really have no idea. I am looking at two 09 Renagades one with 5500 miles and one with 6500 miles, I am very hesitant with that high milage. I usually go by the 10,000 miles is time to start to worry theory but my poo has 11,000+ no problem.

its all about clean air, clean fuel, and good oil. mess up one of those, and any motor, 2 or 4 stroke is not going to last long. The rings on a 2 stroke will still wear out, reguardless of the computer controls. Thats why its called normal maint. Keep an eye on the compressions, and maintain as needed, you shouldn't have any major overhauls. If you ignore the rings and easy stuff, your asking for trouble. Also, off season maint. has a lot to do with it too. foging the motor, and keeping the bearings coated will keep them from rusting. Especially important with full synthetic oils, as by their very nature, they want to flow easily, which means they flow right off the bearings when they sit for a long time. The E-tech has the storage feature for a reason, and they recommend doing it if it will sit for a month or longer.

Use very fresh gas 91 octane and less then 10 ethanol. E-techs prior to 2010 have a very small fuel filter that clogs easily. The key to these motors is allowing ample time to warm up, good fuel, vary your speed, and ride it like a two-stroke should be ridden!!!!

I believe the bearings an an eTec are sealed just as they are on an SDI engine. Which means that fogging is basically a waste of time. After 5 years the electronics will be the greatest concern for the eTec models. Cold and heat extremes combined with the continual jarring environment does bad things to electronic components. People are still having trouble with simple kill switches - what will happen in time to a much more complicated system? In the mean time do exactly what the owners manual says and use recommended fluids. Time will slowly kill the eTec before miles will.

I think doo changed that with etec & now runs oil line to crank bearings. I thought I saw that in a mag etec diagram & thought well doo finally learned sealed crank bearings SUCK! I could be wrong but thought doo changed to oil lines to crank bearings.

'Doo did have problems with the SDI 1000 crank bearings. I owned an SDI 1000 Renegade for a short while but sold it just because I became afraid of the ticking time bomb of great expense associated with crank failure. The whole SDI experiment was a learning schedule that led to the development of the Etec. Hopefully they did something different with the bearings. That being said many of the smaller bore SDI's did not have crank bearing issues. The 600's were about bulletproof. It seems kind of strange to me that 'Doo and Poo can churn out very good 600s year after year but the next step to a good 800 seems to baffle them. Hopefully they both get it right this time. All the Sno-rags are crowing about the 800 'Doo and the much improved 800 Poo. I hope it all comes true for those that plunked down the ching for them.

I remember my buddy got a brand new 800 poo in 2000 or 2001 just before the variable exhaust. It was fast and fun but he said the vibrations were enough to loosen bolts.

i believe you are correct also, i think doo stopped that in 04 or 05? either way, it was a BAD idea

According to the Ski Doo parts catalog, they are still using ISOFLEX lubed crank bearings in the 600 and 800 ETEC engines.

My personal opinion is that I would be leary of any high mileage (>5000 miles) Ski Doo because of the Isoflex lubed crank. I rebuilt my 600 SDI last year proactively with about 5000 miles and found that the mag side bearing had leaked a good share of the Isoflex out of the seal (PTO side looked like new). When the Isoflex goes, so goes the crank soon after....

There are many Ski Doos out there with 10,000+ miles that have never been apart-I guess its just kind of a crap shoot. I think no matter what you have to take the mileage into account when you determine the pricing.

Fogging is still not a bad idea with sealed bearing system, as the rod and wrist pin needle bearings get a shot of lube for extended storage when you fog.

The ETECs have an off-season storage fogging program for this reason I would guess.

I would have to believe that the wrist pin bearings have to be designed differently than other two strokers just because so little oil is used during normal use. Also if you tried to fog an Etec the conventional way how much of the fogging oil would actually make it to the underside of the piston? I don't know. The engine IS designed to run clean. This means very little if any overlapping of ports and transfer passages. Again, I don't know for sure. The Etec is a whole different animal.

We have 2 09 E TECH's with over 5000 miles and will keep them until they have 10000 and then either sell them or tear them down most likely. Its hard to find a low mileage Sled and sometimes age is worse than Miles. I would worry more about how they were stored and maintained.

X'2 on the doo forums many people with over 7,500 miles on multiple sleds no issues. I purchased the 4yr extended real cheap insurance for $399!!!
