2001 Skidoo Mach Z 800 Triple
2001 Skidoo Mach Z 800 Triple
2001 Mach Z 800 Triple has an extremely powerful 800 rotax triple which produces around 150hp as I have been told. The model I had was the “tech plus” which had D.P.M. “Digital Performance Management”, RER “Rotax Electronic Reverse” and tilt steering and adjustable windshield. The snowmobile itself road like a Cadillac but it was not without problems. The carb boots “rubber grommet connecting carbs to reed valves/engine” seemed to like to crack very easily. The nice thing is you could tell if that was problem because fuel would come up the DPM lines and plugs would foul. Also the model did not come with rebuild-able shocks and the HPG shocks it came with were around 300$, so I would fork out for some aftermarket shocks like Ryde FX. The nice features of the sled would have to be the look and feel of the machine. The electronic starter and reverse are the best feature and a must. The gas millage was actually better then my friends ZR 500 which was a surprise. Below is some info about the machine and features.
Engine: 800 Rotax Triple
This engine was known as a legend which powered the mach z for a few years before triple triple engines disappeared in the 2 stroke fashion. The engine is 3 cylinders with a displacement of 796.3cc. The Carburetion was supplied by 3x TM-38 with D.P.M. Technology. The exaust system was 3 triple pipes to a tuned can which has 3 bottom outlets.
D.P.M. / D.E.S.S / MPEM
Digital Performance Management: The system basically varies the fuel delivery by manipulating the float bowl pressure and its adjusts based on temperature and altitude. The DPM unit looks like a black tube that has air hoses hooked up to the carburetors. The DPM has an electric actuator that moves in and out and adjusts the pressure of the float bowl. This is controlled by the MPEM, the module adjusts the pressure based on the air pressure, throttle position, air temperature, engine water temperature and the barometric pressure “mountain sleds only” This also keep the engine running systematically normal through different temperatures as well. Later model sleds incorporate Knock Sensors into the system as well. The MPEM is the “Multi-purpose Engine Module” which is the onboard computer that adjusts the DPM via the sensor data; It also controls the RER “Rotax Electronic Reverse” and the DESS "Digitally Encoded Security System" which is skidoo’s programmable tether cord security. All late model sea doo’s and skidoo has these keys which prevent the sled to be stolen. The key must be programmed by the dealer to work with the sled. The sled will not operate over 3000RPM with the incorrect tether cord installed. Also sea doo’s can have limited teather cords programmed which prevent the machine from going over a specific RPM, which is great for younger operators.
Rotax Electronic Reverse
RER “Rotax Electronic Reverse” most snowmobile that have reverse utilize an extra gear which is in the chain case to cause the sled to move in the reverse direction. This is activated by the pulling of a lever near your right leg on the snowmobile. This was a luxury add-on for most snowmobilers, and most people had to ask and pay more for it to be added. Some cases it would be standard on really heavy machines like the 2000 Thundercat. This system added extra weight and cost you 1HP “Horsepower” per every 100cc. Skidoo developed a system where by the push of the button the engine would stop, then it would start back up with the engine running in the reverse direction. Also the clutch has a special helix which is also part of this system. The MPEM is what controls and activates this system. It’s basically done by two power pickups one reverse and one forward that get transferred when the system lowers the RPM down to nothing and by advancing the timing of the engine as well. This is an amazing part of engineering and besides allowing you to go in reverse, doesn’t add weight or reduce horsepower of the engine. Keep in mind you should let your sled warm up for about 5min before engaging if your machine is ice cold as it will stall the engine in most cases. Also its seems you can go very fast in reverse so be careful getting used to it.
Well I have explained some of the features of the 2001 Mach Z 800, some of these features are found on most to all BRP products today. I hope this explains some of the features better to you and helps you make a decision on a new sled. Personally my Mach z 800 was the best and will miss it a lot, it had these features above and plus some. The sled was really fast and mostly reliable. I do recommend upgrades of rebuild-able shocks, skidoo precision ski’s, and a clutch kit. This will also add to an already fast snowmobile. Please check out my video its me driving my Machz 800 120MPH across a lake. Awsome!!
