Anybody have any idea what a 1979 model mercury 140 inline 6 outboard motor in good running condition worth. It has good conpression on all cylinders and doesn't appear to have a lot of hours but who knows.
If it hasn't been rebuilt it really isn't worth much. If you have a documented rebuild, it will be worth alot more, usually the price of parts and rebuild. Besides Ebay, you could check here.
