Product Overview
Water pump impeller kit for Yamaha 25, 30, 40 and 50 HP outboards, supplied as 1 impeller and 1 woodruff key. It replaces 6H4-44352-02, 6H4-44352-02-00, 6H4-44352-01, 6H4-44352-01-00, 6H4-44352-00, 6H4-44352-00-00, the older 676-44352-01 and Sierra 18-3068. The impeller is neoprene with 6 blades on a key drive, 51.8 mm outside diameter, 16 mm hub and 19 mm high, so it is the small-hub pump used on the 2-cylinder and 3-cylinder 25 to 50 HP gearcases. If the tell-tale is weak at idle or the engine warms up on plane, the blades are usually curled or missing and the liner is scored.
