The first thing you have to do, is join the parent organization at: www.aomci.org The cost is $70 which is good for a 2 year membership After you have joined the parent AOMCI, you can join the "Florida Chapter" for $25 for the FIRST year, then $25 per year after that. By becoming a member of the "Florida Chapter of AOMCI" you get access to our informative newsletter "The Read Cage" which is full of informative articles, meet local members with lots of technical knowledge, participate in our monthly "WET" meets where we take the old motors out and run them. .
One of the best sources is "Peter Hunn's "The Old Outboard Book", readily available for purchase online/
In many cases....yes. Many parts for Evinrude, Johnson, OMC, Gale (which included Hiawatha, Sea King, Buccaneer etc) are still available from BRP, the parent company of Evinrude, Mercury Marine also supplies many parts for their older motors. Aftermarket companies such as "Sierra" supply many parts for the older motors such as water pumps, fuel pumps etc.
Most older OMC, Evinrude, Johnson & Gale manuals are still available from "Ken Cook publishing" Mercury still publishes a single manual that covers its pre-1965 motors. Another good source is the after market manual "Clymer" One of the best ways to find information....join the club. You will find a wealth of information from other like minded people who are more than willing to share their knowledge
That can vary depending on what make, model & year, and of course condition your motor is. Remember, just because it is old does not mean that are not many of them out there. One of the best ways to get an idea, is to join the club. By finding club member with a similar make or model, you can get a better and more accurate idea of what your motor is worth. By joining the club, and going to your local chapter's meet, you can gain a lot of knowledge about your favorite old motor.
