Posted 26 Jan 2021 Hi Avid Flyers!I'm busy with a Rotax 582 to Rotax 912 ULS swap on my Mk4 and me being in South Africa makes getting an Engine mount extremely Expensive!So I was wondering if anyone might have a Drawing of the Engine mount for the 912 so I can build one?Or, If anyone could possibly build me one, but without welding it together? (Just the pipes and parts cut to the correct lengths) to help with shipping cost?RegardsCarel Share this post Link to post Share on other sites
Posted 27 Jan 2021 I can't help with drawings, but just an idea:If you do your own mount, design it to use the Rotax Ring style mount. This gives you more options for engines and factory parts than the four-leg style that is commonly used. Share this post Link to post Share on other sites
Posted 27 Jan 2021 (edited) If it were me and building a new mount, I would build a bed mount like the Zenith 750. It is good to know what muffler you plan to use before designing a mount. The original mount for the MK IV WAS PART OF THE COMPLETE firewall forward package which included the mount, the muffler exhaust cowling, etc. One of the things I don’t like about the original is the ignition modules and coils are mounted on the motor mount. So what I am saying is maybe the original mount without the rest of the parts my not be the best way to go but is doable. Not really what you asked, just maybe something to ponder. the pix below is of a bed mount a friend built for a different aircraft.

Posted 27 Jan 2021 Yes I believe I would do the same. If you would need to buy the ring mount for a 1000 USD, NO, you can have a mount built for less than that. I do have a ring mount and the rest of the mount for a Zenith 701 but I haven’t decided to let it go yet. Share this post Link to post Share on other sites
