I weighed the completed Tailwind engine mount today.  Every thing,
including Barry Isolators and bolts, etc was 25lbs 14.5 Oz.  This
includes 8.5 lbs for the gear mount.   Without the gear mount, a good
firewall forward figure for most applications would be around 17 lbs.
Not bad when you consider that the PSRU adaptor plate is included.

Tracy's original mount with out the PSRU adapter plate was 28 pounds.
I don't think that included the 3/16" thick 4130 steel plate between engine 
and oil pan. With out holes or ears (13" x 18") that would weigh about 
13 pounds on its own.

The Tailwind and Tracy's RV4 have similar gear mounts.
