Three blade stainless steel prop. I have used it for about an hour. I came on my boat and I needed a lower pitch prop, Its in excellent shape and has no scratches or dings. Part #48-16546A46 , Diameter - 13 7/8 Pitch - 21, Right hand (standard) rotation. It fits Mercury outboards 75 hp and up and Mercruiser Alpha Sterndrives 3.0L-5.7L. It could also fit non Mercury products with the correct hub. It has a high-rake design for greater bow lift. Works great on bass boats and bowriders. This prop is designed to be used with a Flo-Torq II hub system which is not included. I would like $250 FIRM. I will be glad to ship this prop via UPS with prepayment. Payment by cash or USPS money order only. PM me or e-mail me at flatriveroffroad at yahoo dot com Thanks.
