Product Overview
Water pump impeller kit for Yamaha 50 HP class four-stroke outboards, supplied as 1 x complete kit with pump cover, impeller, wear plate, seals, O-ring, drive pins, gasket and key. It replaces Yamaha 63D-W0078-01-00, 63D-W0078-00-00 and 63D-W0078-03-00, and suits the F50 and F60 from 1995 to 2022.
