I'm looking for any information on an old Johnson boat motor model A-45 #119715 . It's been in our family since it was purchased new. I'm hoping someone can help us with the history and actual age of the motor. My wifes's Grandfather had the motor restored years ago and now it just sits on a display stand. We turn it by hand every few months to maintain it. Do we need to do anything else? Thanks in advance for any info.<br /><br />Kevin<br /><br />Photo: http://www.aquariumdvd.com/MVC-021S.jpg
