What year

[Corona23]

This 20 hp Evinrude I bought as for spareparts, but under the hood it looked too good to slaughter, so now I will make yet one more outboard running.
It only wears a Serial number, but i actually don't even know what decade it was made (sorry)
Can anyone with more experience tell ? Then I can order spareparts
Thanks in advance.

Looks to be a 1975 model.-----Excellent motor.----Easy to find parts.----Easy to maintain.

I concur it sure looks like a 1975 model, and a fine motor overall. The 20 was not available in the U.S in 1975 but it was in Canada with a built-in 45 watt a/c generator.
