Re: Old Evenrude motor
An FD-22E is a 1968 Johnson 20hp motor. There are still quite a few parts available for it, according to shop.evinrude.com, but the parts that would make me a bit nervous, are the water pump impeller and housing assembly. They are now classified as "limited availability." If you want to keep yours running for awhile, I would buy a few impellers and keep them in your own parts stock. Same thing with the housng
The impellers are currently about $19.00 each, so buying a few wouldn't "hurt" too badly. The housing assemblies are about $60 each, so buying a couple would be a bit more, but not "out the box."
