Up for grabs, I have a power trim unit removed from a 1989 120 HP Evinrude outboard. 

The Power trim unit is in good working condition as seen in the video

I believe it will fit V4 and V6 Johnson / Evinrude outboards. 

The power trim unit was used mostly in freshwater with only a small amount of saltwater use.
