Your best resource right now is Craigslist.
See whats for sale there in any given price range.
The smart buyer these days go thru a check list...
What are the motors worth ?
What is the trailer worth?
What is the hull worth (this in your case is the hard part)?
The first two are known values, the last is what someone is willing to pay.
All electronics are at least 50% off going prices.
Hopefully when you put it up it will go to someone on the sight
