Re: 2 mercury mark 5
Parts are also available at
www.oldmercs.com, which may be a mirror to the east coast marine site...anyway they have a lot of old merc stuff. Value depends on where you are and what the buyer wants to pay that day. Check for a local AOMCI club/chapter in your area at
www.aomci.org. If there's a chapter nearby, they should be having swap meets soon. Those guys can tell you all about the old motors and you may find another treasure at their meets.
