Hi i used to have a differnt user name but cant remember it. but anyways .Today I just bought a boat for a steal of a deal. It has a almost bran new looking 1968 i think mercury 650. sn# 2448260. It has been sitting in a garage for 25 years on the back of this boat and has not seen daylight till today. I was wondering how good of a motor this is? I put in gear and turned prop manualy and has awsome compression. I need to know what i need to do to this motor before i even think of starting it. I am getting new impeller first off. what else should i do? seals? gaskets? ignition? and what is the fuel ratio? I can do the work myself. any help would be greatfull. I still cant beleave how new it looks. not a scratch or any chipping or paint fadeing at all and totaly complete.
