Details:

Unfortunately, that is all I know about it. I purchased boat for a project and only wanted the outside of motor. I bought from his widow and she stated the motor ran a couple years ago. I never started it, nor did try.

I can part it out for more money but thought I'd offer up to someone looking one. I will bot it up and ship as best can so there isn't any damage. This was a one owner motor. I included some photos of the model and serial number that were in mount.
