I need an aluminum 3 blade prop for my 1987 SeaRay, 4.3 4v 205hp, OMC. I ordered one from an iboats recommendation and the thrust washer wouldn't fit all the way down the shaft. They put me in contact with Solas and after 10 calls, they didn't know the problem. Back to iboats and they overnighted me another prop. Same problem with the thrust washer. What are they doing wrong that the thrust washer they send with the new hub won't fit down the shaft, and my existing thrust washer is too big to fit in the props they're sending.
