Restoring these old outboards is a hobby. I do this in my spare time to give me something to do. (yes, I have a full time job that takes precedence) The fun part is that each motor is different and therefore things never get boring or mundane. When it is no longer any fun, that is when I will stop.
I believe there is a place for these vintage motors. Most were built to be reliable and long lasting. They can also be used to inspire our youth and to learn.
These motors are used but a long way from used up.
