I just got a 7.5 HP Mercury outboard. I am trying to get what model/year I have in order to get parts for it. The serial number tag is damaged but I think I can read enough of it to figure it out.

The numbers I see are as follows

281?525 The center number I cannot see.

Now when I look at this chart I see numbers that are close, but not quite:

I am guessing it is a 1969 or1970 motor??

It also says:

"Kiekhaefer" on the front of the Aluminum/Metal cover and has "Thunderbolt Ignition" on it.

It has good compression. I squirted a tad of gas mix in the carb and she started right up. I intend to put a new water pump in it and basically clean it up and check the oil.

What do I have here? I have never owned a Merc. Bob

Yes, 1969 or 1970. The middle number will determine which year.

Doesn't matter anyway, the pumps are the same for either year. Part # 46-46893A6

Thank You. Looks like parts are scarcer and more expensive for these Mercury motors than Evinrudes.
