although there are some items that deteriorate due to age.
Start by giving motor a cleanup with a mild detergent and gentle scrubbing.
Be careful not to damage decals or fade paint.
It would be helpful to know your mechanical background before making suggestions
as to what and how to evaluate condition of motor.

Wizard WF7 is based on Mercury KE7/KF7 Similar,but,not exactly the same.
