Information and Year

[cook7200]

I have a Mercury 500 Thunderbolt Ignition. The Serial Number is 4708498. I have not been able to find any information on this engine. I would like a shop manual. I am not having any problems, matter of fact it runs great. I would like to know gap setting on plugs, electrical blow up sheet, and remote parts picture. Thanks for your help.<br /><br /><br />Michael
