Earlier, I referenced a 1962 Johnson, being on a boat my family owns. I
don't know the exact year of the boat. Some people think it's a 57
Glasspar Avalon, whilst others think it's a 58. The confusion stems
from the fact it was bought when my father was 12 years old, but the
first motor on it was a 1958 50 horse Johnson.

And some of the registration papers have different years. Is there a
simple way to find out what year the boat is?
