You are not really doing anything wrong. You just have a lot against you.
1. Very small town. You need to sell locally because shipping is murder. So you are too rural.
2. The motors are all apart. No one knows condition of parts. Lots of work to put all together. bearings, gaskets etc., etc.......they dont run.
You are in "basket case" territory.
3. Those motors don't sell well on a good day. Limited popularity.
4. Price is high to most people.
5. I'm sorry for your situation and personal loss.
6. The more places you advertise the better it is. Facebook is free, Ebay is good.
7. Parting out may be the only way. You then need good pics of each and list each separately and find boxes and ship each.
8. Give it time if you can....or it's scrap time. That would be emotional but will fade into moving on.
9. I hope I'm wrong
