My experience, putting a motor in a box, not only protects them from dents
& breakage but also reduces the effects from seasonal changes when stored
in an uncontrolled environment.
If there is a chapter near where you live and they have a wet meet, if you
were to bring your motor, I’m sure you would find a boat to run it on.
