Value of Rotax 447

Recommended Posts

Hi there guys,


I have a Rotax 447 which was for one of my dad's ultralights from back in the day. He claims it has never been used. I've inspected it and it does appear to be new but it is missing the CDI unit and the muffler. The carburettor would require a rebuild as it has been in storage for 30+ years. The engine has an OEM Rotax gearbox also.


If I were to run a compression test and the cylinders are good. What would this engine be worth as is? I presume this engine is discontinued as I can find is mainly rebuild kits and spare parts for them only.


Any information would be greatly appreciated as I don't know much about aircraft.




Thanks guys :)

Single carb single breaker points ignition - very old engine and it appears from the pics to have been used so not new.


Given it’s been sitting for years with unknown background it will not be worth much as a strip and internal inspection is going to be required - two strokes sitting for years need a lot more than a compression test as internal corrosion is the issue.


Last 447 same as yours I bought had only been sitting for 6mths since removed from a hovercraft and I paid $350 for it and overhauled it.


Sorry that’s not what you wanted to hear but not many people fly 447s and nearly nobody flies the old breaker points ones.

Thank you for the reply,


To be honest, I wasn't expecting much for it. I just wanted an idea so I can list it for the right price.


Thanks for the information
