Good Day,
I've been looking for over a week now but cannot locate a source of engine shock mounts--Diamond Aircraft Part Number 7850000. Does anyone have a contact, source, or magic bullet, please? The engine is a Rotax 912 F3.
Thanks, and fly safely,

Hi Keoki,
I should have a set of these. The part is Megi 785000. Conti makes then now. It is a little bit of a PITA to remove the old ones btw. The maintenance manual doesn't detail the R&R process. It's up to the user to figure out...
Feel free to PM me. I replaced mine about 10 years ago. Due to shipping costs, I ended up purchasing more than I needed. I'll have to look up the price I paid and double check how many I have left. I know I have at least another 4 units.

John,
Just so you know - Keoki is the instructor at the high school where we donated our Katana. He gave my son his first lesson in the Katana many years ago (my son is now a pilot at a major airline). Appreciate any help you can give him.
Keoki is also a very experienced A&P. He repaired the Katana years ago after the nose wheel fracture and prop strike.
Cool video if you have time to watch it -

Hi Keith,
Thanks for the update. I "know" Keoki from another DA20-A1 parts issue. Seems like a good guy, thanks for the link.
I emailed him directly.
I was at the hangar this weekend. I still have 6 of these rings. If anyone needs sourcing of these parts in the future, feel free to PM me or reply to this thread. I don't think there are too many of us Katana owners on this site.
best regards,
John

I need to order a set of these for my new 912-F3. Apparently the 785000 comes in two hardnesses. Can you determine/remember if it was the softer 4000008372, or the harder 4000008373? If anyone else would like to get in on the order, let me know. -Al Gibbs, Katana owner.

Hi Al,
I'm on vacation this week. I shared a US based company that can procure these with another user on this forum. I sold my remaining ones to Keoki, but would be willing to go in on 4 new ones if you are going to order some. The main issue is that shipping I think was expensive, so you might as well buy extras to lower the cost per unit. I can look up the hardness from my previous order with them when I get back home next week.
thanks.
John

It looks like when I ordered them back in 2010 they had 2 duro levels. A soft and medium. I ordered them in the medium "60 Shore". Worked out great for me. They are kind of a PITA to install (I think I mentioned this before). From memory, we were able to leave the engine in place using an engine hoist to support the engine while we swapped them out. I think there may be another party that is also looking for these. I'll check thru my emails.
