I picked up (well, technicaly my wife did) a Merc 200 at a garage sale for $130 (started at $200) with the fuel lines and tank. I have been looking for info online and I have seen both 20 and 22 HP ratings listed. I think it is a '61 when I looked up the serial number. What is the actual rating? According to the seller it was tuned up last year, but he sold his boat and the new buyer only wanted the electric. He had been moving this motor around his garage for a year with no boat to put it on. It looks pretty clean for it's age and the plugs did look new. I would like to get an owners manual and a repair manual for this motor, does anyone have any suggestions where to find these? Is there anything else i should check before taking it to Canade next week?
