HI GUYS,<br /> yesterday i bought a 40 hp. merc from a friend of mine for $50(i figured i couldn't screw up too bad) . it seems to be in descent condition except the top cylinder has no compression and some of the wires from the power pack are corroded real bad. i was looking for some good pointers before tearing this thing down seeing as how i haven't much experience with mercury. any suggestions would be helpful.<br /> THANKS, LIKEAROCK
