Test compression no matter what. If the numbers are low and/or off 10 percent from each other than the lower unit is the most valuable part and you should look somewhere else. Price on a motor with 120 psi versus a motor with 100 psi will vary. Also the area you live in makes a big difference. So $250 to $800+ depending on local market.

If it runs perfectly, starts easy, etc, probably around $700-$1000. If something is broke and/it is missing parts or incomplete, $200-$400 as a parts motor.

the boat is a excellant aluminum boat. I dont have anything good to say about mercury though
Unfortunately to find out the year of a Mercury boat motor one needs not only the serial number, but also the horse power rating. This allows it to be narrowed down to a specific year.
