Been wondering ever since if the cases on the Rotax engines are gearbox compatable like the older 583 sled engines. Anybody had a close look at the PTO end of the newer Rotaxen?

It's accustomed accessory noise, you'll apprehension it's added arresting if axis the prop one way vs the other, which has to do with the circling gears. The babble is just the slight bulk of baste you commonly have.... _________________ Aprilaire humidifier (http://www.aprilairehumidifierparts.com/) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=251286#251286 ________________________________ Message 3 _____________________________________ Time: 05:41:15 AM PST US From: Herb Subject: Re: Kolb-List: Re: New alternate engine on my MKIII Fantastic Jason... Hopefully the little engine will have reliability and wearability attributes of the 912s... no reason why it should not... I notice that Rotax is selling a three cyl, 4 cycle engine with throttle body injection in the Ski Doo... for similar money...similar hp..

I do believe the total install with radiators, exhaust, gearbox came in at about 180# The new Yamaha snowmobile engines have a little larger displacement (1050cc), are fuel injected, and weigh a couple pounds less. I chose not to go with the fuel injection because when you change the intake and exhaust you need to rejet the carbs. I feel to properly adapt the fuel injection engine, you need to get a mapable injection system and put it on a dyno with all the instruments to get the fuel delivery correct. With the carbs, I change the jets and read the plugs. It is interesting that Yamaha fuel injection does not use a O2 sensor so once it is set up, it would be ok to use 100LL. I hooked up with the person who made the gearbox adapter on the rotary forum.

On a snowmobile, they use full throttle in short bursts, very little time is actually spent at 7000 RPM. Think about it, a 120 HP snowmobile would be up to over 100 MPH in about 5 seconds at full throttle, most time is spent at far less RPM and power. That being said, maybe the Yamaha engine would last a long time if it were limited to 100 HP and maybe 5500 RPM on a Kolb. One other thing I really like about this conversion is the Rotax Gearbox, that should solve a lot of potential problems right there. This sounds like a very interesting alternative engine, I hope it works out ! Please keep the information coming, a lot of people will be interested in how this engine works for you.
