I recently bought a 7.5 hp merc outboard that appears to be in good
condition. The seller indicated it was about 15 years old. I think it
is a lot older but have been unable to determine the model year. The
serial number is: 4253791.

Thank you in advance for any info you might provide.

1975.

1976 serial numbers start at 4314385.

15 years, 31 years, what's the difference, right?

For a 7.5 they are like dog years :-) they have there own type of
measurement. I have a 71 merc 7.5 on a little tinney that runs great.

Did replace the stator and coils after 30 years, but hay.

Agreed.
I have a 1968 6hp Evinrude that runs like a sewing machine. I've
changed plugs, impeller, and gear oil over the years and that's it.. I
store it on a stand and give the starter rope a little tug evey few
months. When I need it, it always starts within a pull or two. Even
after it hasn't been started for a couple years.
