[Rhodes22-list] Converting Electric Winch Motor Lift to a Manual System

[Jesse Shumaker]

With all the replies on this thread, I can't recall if there was a photo of
one of the GB produced manual motor lift.  From all the discussion, it
appears there may have been multiple versions as it evolved.  While I was
in Michigan, I happened to notice that Bob's boat had one.  See the
attachment for a photo.  It lifted easily enough, though it was only
supporting a 5HP 4 stroke Honda, which appeared to be smaller/lighter than
the 9.8 HP tank on the back of my boat.
