Subject: JabiruEngine-List: Engine Mounts

Guys 
My engine mounts are loose and the bolts are bottomed out. 
I noticed there was about 3/32" gap from the back of the engine mount to the front
of the back rubber doughnut on both sides of the top engine mount. 
I am getting word that the original rubber mounts are needing replacement some
as early as 100 hrs or so. I have tightened mine up once but now the bolts are
bottomed out. I am pondering whether to replace with the original or go with
the higher Durometer Sonex. 
You may want to check yours on your next "Conditional". 
Has anyone on this list had to change out their engine mounts? Why? 
Any info would be appreciated.

Bobby.
      Just received a set of engine mounts from Sonex (about $65 with 
shipping).  I was willing to spend this much extra to try to avoid 
changing them within a short amount of time.  Purchased a partially 
completed kit with the Jab 3300, ser # 3a 1437, so it hasn't flown yet.  
Thank you for mentioning about the looseness you experienced.  I will 
change the mounts and probably hang the engine next week.  Each of the 
rubbers is identical, there is no thicker / thinner, top / bottom 
difference.  Haven't  yet compared the hardness but the new ones seem to 
be harder.
      Sorry I don't have the information you need but I wanted to thank 
you for reinforcing my decision to spend the extra $$$
Richard.
