NEW AMERICAN TURBINE HI-HELIX 17-4 STAINLESS STEEL IMPELLER, ALL SIZES. THESE FIT BERKELEY PUMPS. WE WILL CUT AND BALANCE EVERY IMPELLER AS PER THE CUSTOMER'S APPLICATION. WE TESTED A FEW OF THESE FOR A/T WHILE IN THE R&D MODE AND WERE VERY IMPRESSED. I'VE ONLY USED THEM SO FAR IN SOME PRETTY HIGH HP BOATS AND REALLY LIKE THEM. I THINK THEY WOULD ALSO WORK GREAT ON ANY JET. ALSO CARRY A FULL LINE OF A/T PUMP PARTS AND ACCESSORIES AND MANY OTHER JET BOAT PARTS. WHEN ORDERING, BE SURE TO LET ME KNOW WHAT CUT ON THE IMPELLER. IF UNSURE, MESSAGE ME AND I CAN HELP YOU DECIDE ON THE RIGHT IMPELLER AND CUT FOR YOUR APPLICATION. SHIPPING COST INCLUDES INSURANCE. THANKS FOR LOOKING .
