Hi<br /><br />I've bought an old small Sportsboat with a Mercury Outboarder. Engine cover says "50 Thunderbolt Ignition" and the serial Number is 9292032. I've verified some model lists on the net, but I can't find a 50 HP model with a serial Number that starts with 9... .<br /><br />Can someone help me identify the engine and its year of construction?
