Re: Oat
Thats a good question. I've never thought about the temperature being too cold for the gear box.
It seems to lose something in the translation but anyhow the Rotax two stroke operator's manual http://www.rotax-aircraft-engines.co...kus/d04495.pdf lists the engine start/operating temperature as -13F to 120F.

Just a thought....
You don't need to preheat snowmobiles. How would a 582 differ?

Re: Outside air temp
Hi,
I used to have a Pelican Club UL that had a rotax 503 dual carb engine in it back in the 80's.
I flew that all winter, my temp cutoff for flying was around -20 C = - 5 F , I would preheat the engine compartment for an hour or so using an electric car heater, with a sleeping bag over the cowl. I would start preheating the engine at temps around 20 F , it made starts effortless ( no electric start) and gave the piece of mind that things were warmed up a bit for the start. Flew that setup for 350+ hrs with no problems .

Re: Outside air temp
I think it's not a problem,,because the gear is always in oil not like piston in cylinder with a fine layer of oil,there it's a problem with cold....???And on rotax service .com he said you can put synthetic oil...better.....

Re: Outside air temp
Wouldn't the Rotax-Owner.com forum be a better place to get answers to questions like this? It is a very good forum IMHO.
