Hi Jesse,
I bought a 20year old Sries 5 and have the same situation(if not more pronounced sagging wise).
Could you post what you did to fix it if it had to be fixed.
Pauls Engine Mounts look a lot mor "in line".
Thanks,
TUNA

😔 too bad
So what does the forum say to the condition of the engine mount?
I got a reply from him via E-Mail :-)
I bought a 912UL powered IV that had 58 hours on it. It sat in a garage for about 10 years and then I bought it and started upgrading the necessary components.
The Rubber mounts were shot.
I wish I had known then what I know now, but the bottom line is ... replace them if they are old.
It's not worth the excess wear from vibration on that motor or associated airframe components.
Paul Leadebrand once told me that idling during taxi at 2200 plus was just fine because brakes were cheaper than gearboxes. His point is, if there is a sacrifice to be made, do the cheap one. Rubber in the mount system is cheap by comparison to just about everything else on the motor.

Just changed the engine mounts (Series 5 912ULS).
Not a joyful task but anyhow.
I put the engine on a hoist and lifted it up just enough to free the mounts ( they were sagging a lot ) and changed one at a time.
The mount I got here in Europe (Ulm Technology Silent Block) have a shorter bushing than the ones from 1994 Kitfox. I think I read something about shortening the original ones, but can't find it anymore.
The engine sits now nice and firmly in the mounts, no sagging.

Pretty easy if you go about it the right way. Bottom bolts, Remove the 2 bolts (17mm) that connect the engine cradle to the bottom of the engine block, and you can easily slide the bottom bolt right out still in the cradle
Cant seem to be able to cross post images.
