Re: Markings on Brass prop q's

The "gan" is probably the last three letters of Michigan. The first ones were probably not stamped in deeply enough or were worn off.

SMC 54 A would be the numbers that define the model prop. And I believe that SMC is also Michigan terminology, reinforcing my thought that the prop is a Michigan.

Unfortunately bronze props are no longer made and the fellows here on the prop forum seem to have difficulty identifying them.

Try the Evinrude/Johnson forum or try finding the Michigan website where you might be able to get help from customer service. Only other help would possibly be on the old outboard site--don't know the exact address so you need to play a bit with Google.

So no one could have a guess on what pitch the prop has??
