Re: 1958 Mercury Mark 58 50 hp
It certainly has some value, but knowing it turns over isn't a whole lot to go on. Condition - both cosmetic and mechanical - go a long way towards determining a value. Plus, in the end, it is only worth what someone is willing to pay for it. That's why I can't tell you it is worth $X00 or $Y00. Someone else will have a different opinion on what it is worth.
That said, it is definitely worth more than scrap value and would have some collector interest if listed on the AOMCI.org site's ad section. They are good motors and being that it turns over, it is likely that it could be made to run...
