I made these motor mount brackets
like those in the plans. I departed
from the motor mount method described
by William Wynne in favor of making the
brackets and the motor mount more like
those described in the Zodiac plans.
The difference is that Wynne describes
a spool on the motor mount that a long
bolt goes through.
The Zodiac plans
call for shorter bolts going through a
plate on the motor mounts.
