Emblems are hard to come by. The best bet is ebay. The other option is a bit more pricey: If you have a good emblem, I can make you another. It will be identical, but plastic, not metal. And they are not cheap.
I think thats my plan b, trying to make my own....or just not having one at all. I have the one in the picture on the starboard side, just not port logo.
Here is a photo of the emblems I make for MFG, and the rub rail end just below the emblem. If you haven't done this before, I'd be happy to share how I did it. Just send me a PM.
