Dating vintage neptune outboard motors

Rated 3.91/5 based on 994 customer reviews

At per hour, it doesn’t take much time to exceed the value of most motors from the 1940’s and up.

True, there are some very old motors and some very rare motors that are worth a lot relative to the average Elgin, Scott Atwater or Johnson TN-26 – unfortunately those outboards don’t turn up that often.

Since only a small portion of people spending their disposable income on boats are interested in a 40 or 50 (or more) year old outboard, there is a pretty limited market for old outboards.

About the best tool available is Peter Hunn’s OLD OUTBOARD BOOK.
