I picked up 2 of these props with 2 hub kits for our Twin Yamaha 50 HP motors. It came in less then a week with standard shipping and was very easy to install. I haven’t used it yet cause we also checked our leg oil level and found that the propeller shaft seal was leaking on one of our motors so we have to replace the oil seal first and after that we can head out in the ocean and try out the the props.
