Proper way to bench test power trim unit

[jamescarrollpittman]

I removed the power trim unit from my Evinrude 1984 115tlcrd OB motor in order to replace the power trim motor. I would like to test the repaired trim unitit for operation prior to re installing the unit. Is this possible and practical and if so what should be the procedure? I have an idea how it should be done, but not that confidant.
Thanks jamescarrollpittman
