Re: Best Source for 59' Sea King Parts?
Yep, your motor is a 1959 3hp made by Gale Products Division of OMC. The magneto is OMC's "Universal" magneto and parts are available all over the world. Including iboats. The water pump impeller, properly called a "rotor" is available from Brian Wilcox at www.pfs-ware.com/impellers.htm" Don't use the (").
Carb parts are a little tougher. Mercury makes a float that will work with some modification. Fortunatly they usually don't need anything except that and some packings.
For hard-core parts, go to the Antique Outboard Motor Clubs website aomci.org and post a free want ad on their Webvertize page.
I have one of those motors, branded Gale, and it runs like a charm.
