I bought an old mercury outboard last night. The owner didn't know a lot about it, because owners before him had painted it camo, removed the stickers, repainted it phantom black (by hand), etc...so there's no stickers on the motor cowling now and I only have his word for the HP and age. Having seen these many times, I'd guess that it's in the mid to late 60's. He believed it's a 1966 20 hp, as he was told by the previous owner. I'm trying to verify it. There isn't a model number on the motor that I can find, but the serial number is 1965850. Any help figuring HP and year? If not, is there another way I can verify it?

I'm not sure about mercury's, but old Johnsons had the model number on the engine block. The other option is to contact Mercury and give the serial number. They may be able to find out.
