I know there are a lot of smart guys on here so I am hoping someone can help me. My new rib (Zodiac) came with a Yamaha V6 4.2 L, I was surprised to see a black prop (aluminum?) but now I am thinking it may be a painted Yamaha M T but I don't know what one looks like, the Dealer no help either. It has 19M stamped on it. In hindsight I should have taken it off before I launched (at the Marina) and looked for a part number. I am hoping someone can recognize it. Performance wise it seems good 5800 rpm at 58 mph. That said if its aluminum I am sure I can pick up speed and handling by converting to stainless. Thanks !!
