This is not the SDS prop with the dog bone spacer, but the round one. It is a 2022 Yamaha F115 equipped with this Talon SDS prop (K 13 1/8x16) . The prop has side to side play, though slight, but troublesome. I bought a new one just like it as a spare, along with a new thrust washer and spacer. It has play also. A Yammmie mechanic and a Yammie parts dealer told me it was normal. Most people are unfamiliar with this problem and SDS system. My shaft has no play. Anybody out there have the same experience with this?
