Re: how much is this outboard motor worth
Gave it to you? That's odd. Does it run? Have you heard it run? Recently? I can't imagine someone giving a 200 hp late model outboard to anyone if it was in running condition.
It's worth a bunch if it's running well. Trouble is, you may not have a way to demonstrate that to a prospective buyer since it's not on a boat.
You can look up asking prices on various web sites, like Craig's List and eBay. Still, without being able to demo it to a buyer, the price would be what a non-running outboard would be.
One other question: Did your friend have a boat? If not, I wouldn't try selling it until you're sure it isn't stolen.
