1993 evinrude 9.9 hp outboard
That said, whether it is a 1985 or a 1993 does not matter much. If it is in mint condition, you might get $600, $700 on the very best of days for it. If it has a few dings, but is a good runner it is worth $400-$500.
A new 2014 9.9 books out around $2,200.
Also, it is the absolute worst time of year to sell an outboard. You would have a much better response in spring.
Having a few issues with my 9.9, I may have interest... Shoot me a PM...
