Listed here is a NEW Sea Water Impeller Pump Bracket.  This is a Genuine OEM Mercruiser Mercury Quicksilver part NOT a cheap Chinese aftermarket replacement.  The part number for this bracket is 8077491.  The number 807749-1 is stamped directly into the part.  This is how you can tell the factory OEM parts from aftermarket.  Order is for ONE bracket NOT all 3 boxes.  Only opened one box to take pictures, check condition, and take measurements.  Its officially called a Sea Pump Bracket but is commonly referred to as impeller mount bracket or water pump bracket.  Brackets came off the assembly line on March 6, 2025 so they are NOT old stock that has been laying around forever.  These were used on many Mercruiser V6 and V8 engines mated with Bravo sterndrive gear cases and some inboard applications from the 1990s well into the 2000s.  These were primarily used on the pumps with the plastic housings.  One of the brackets you see pictured are one of the actual parts you will receive with nothing extra.  It comes in factory box.  If you prefer one over the other send me a message and I will do the best I can to accommodate you.  Brackets are stored in a climate controlled parts room to prevent deterioration.  If you have any questions or need help with compatibility please feel free to contact me before purchasing and I will help you to the best of my abilities.  Thank you for your interest.  Steve MMSLLC :)
