I ordered my motor mounts from Barry Controls today and I was shocked
at the cost $6.18 each for Neoprene.

Of course you realize that neoprene is pretty miserable when it comes to
temperature.  I forget the actual numbers.  IIRC the stuff goes away around
180F by the book numbers.  You will get reduced life under the cowl
compared to some other materials.  OTOH, I believe this is fairly common
practice.

Is natural rubber better? They are also available in natural rubber
for about the same price. Lycoming mounts are made with natural rubber.
Neoprene is supposed to be better in oil.

BTW Mine came in the mail todays. Pictures in a few days.

According to the Service Rubber Group handbook (they supply the rubber
dampers for my re-drive) neoprene is good to 250 deg. F.  Natural rubber
only goes to 175.
