I just picked up an old boat with a 500 50 hp kiekhaefer mercury outboard on it.I cannot find the model or serial numbers.It has thunderbolt ignition with the distributor,and it is a four cylinder.Could anyone tell me how old this unit is,or tell me where i can find that information?

The # will be on the swivel bracket just above the transom clamps,it might be on the starter bracket,failing that get the carb #'s and the colour of the wrapround may help narrow it down,at a guess being a 4cyl somewhere between '63-'78easy

I have the same engine, I just bought an older boat and it came with that. Serial is 7061177. To some of you these may look like stupid questions, but: is it a two or a four stroke engine ? How old is this motor ? Does anyone have an exploded view of this engine ? I'm having problems with the water pump and I need to know how to fix it. Thanks.

That's a Canadian # and I'm not familiar with them nor can I find a list online,over to Graham with that. There's a 99% chance it's two stroke and have a look here for your motor. http://www.crowleymarine.com/mercury-outboard/parts/474_19.cfm .
