How does it look ? I have seen hill-climbing, it was kind of high tuned ones, and some do not survive..You likely have never been on a sled trip in the north country.

The Onex was originally intended for the 80HP Aerovee, but they also allowed the 100HP turbo version. They appear to support the UL350 which is up to 130HP. Sonex does support the 912 for some models, but they don't make a mount for the Onex. Prop diameter is a significant limitation.How much can a Onex take? A 912 is going to make it a rocket off the bat.
Buy used rotax, with good bottom end, and give him a new set of high compression pistons. 750usd i think. All else same, gives you 90-95hp.80HP Aerovee, but it would be nice to have more power I bet.
Hours and hours of high load on rough surfaces at low speeds (mostly). I imagine the stresses are similar to WWI dogfighting.How does it look ? I have seen hill-climbing, it was kind of high tuned ones, and some do not survive..
Have you ever had to buy certified aero engine parts ? You wont be happy !It sounds like a good deal if I needed the power. But I don't, and the AM13 appears more sorted. Still thinking a used O200 is a better deal, though I'm a sucker for an auto conversion
It looks to me, that they tape the throttle wide open, and just hang on for a few hours till the next stop (break)How does it look ? I have seen hill-climbing, it was kind of high tuned ones, and some do not survive..
I'm an A&P, so yeah.Have you ever had to buy certified aero engine parts ? You wont be happy !
Aren't you going to have the same prop dia issues with the 80hp 912?The Onex was originally intended for the 80HP Aerovee, but they also allowed the 100HP turbo version. They appear to support the UL350 which is up to 130HP. Sonex does support the 912 for some models, but they don't make a mount for the Onex. Prop diameter is a significant limitation.
I'd hope my 80HP 912 will be better than the average 80HP Aerovee, but it would be nice to have more power I bet.
It's not ideal, but manageable for 80 HP. More HP would likely require taller main gear.Aren't you going to have the same prop dia issues with the 80hp 912?
Would love to see your build blog when you can.I’m putting a yamaha Apex in my project. I should have everything firewall foward done for about 10 grand. I looked at about everything before deciding to go with the Apex. The big reasons that stood out to me was the base engine is as bulletproof as they get in the snowmobile world. I also personally prefer yamaha engines over anything BRP makes including the 912. I wanted efi, liquid cooled “I live in Minnesota and want a good heater”, and light weight. I oversized the engine mount quite a bit but should still have a flying engine for under 180lbs installed. I also really liked how I could throttle back to still make that 100hp. Vs. a lot of the other options which make 100hp max
Aka, the eternal search. Not yet found.

Well in my direct experience, A+P mechanics do not buy parts, they are basically parts changers, condemning good, service parts to the scrap bin, then the customer has to buy the parts, mostly.I'm an A&P, so yeah.
Plus parts availability of that 1.3L engine is pretty amazing. Truly a global engine
