Selling a never used brass propeller my uncle bought for his boat but sold before installing it. It measures about 12" diameter across and 4" diameter across the outer inner shaft casing. I tried my best to take as many pictures for context. The markings on it are 19p Michigan smc 232. I priced it much lower than other similar ones I found online as I hope it finds a good home. Will try to answer what I can but don't know much else. Email if you are interested or have any questions. Reasonable offers will be considered.
