Neal,

Just what the Hell are you talking about?
Your boat doesn't even have a fixed prop. Your vessel doesn't even have
a fixed motor! Your boat isn't even a true Aux. On a true Aux, with the
Prop mounted "Abaft the Rudder" as in a off set shaft, Reverse is a
bloody Nightmare.

Get a true Auxiliary with a decent fixed engine ad learn what the hell
we are talking about. A sailboat with a decent mounted inboard engine
and a proper designed sailing hull can have problems in reverse.

A garbage scow can go forward or reverse equally well but it sails lousy
