Jason, others,
I noticed four or five years ago that Rotax was building these high
performance three cylinder four strokes like your Yamaha for their
snowmobile and Sea Doo lines.
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?

To acknowledgment your catechism about the gearbox babble - that babble is altogether
accustomed if active the rk-400 clutch. 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....

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

I finally managed to post three short video's on my blog. Not sure why
but it took forever to upload the video's even though they were short.
The quality also sucks as well. Can't have every thing I guess.
I made a 3 hour flight with it today and posted the pictures and
findings on my Blog. You are welcome to view it if you would like the

I did not weigh the engine before install, but I do know the bare engine with carbs
weighs 119#. 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.
Below is a link to a lengthly thread if you would like additional information.

would be really helpful....Hope everyone on the list is as interested

I doubt the engine would last long at 7000 RPM. 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.
