Water Pump Impeller Kit 662-44352-01-00 47-81242M for Yamaha Mercury 8 15 HP Outboard
Water Pump Impeller Kit 662-44352-01-00 47-81242M for Yamaha Mercury 8 15 HP Outboard
Product Overview
Water pump impeller and key kit for Yamaha and Mercury outboards, measuring 39.65 mm outside diameter, 14.08 mm inside diameter and 21.96 mm deep, with 6 blades on a key drive shaft. It replaces Yamaha 662-44352-01-00, Mercury 47-81242M and 47-95611M, matches Sierra 18-3063 and cross-references Mallory 9-45608. Fits Yamaha 8 HP and 15 HP models in the serial ranges listed below, and the Mercury 8 HP and 15 HP built in 1977, 1978 and 1987. The neoprene impeller is the part that sets when a boat is left standing; it takes a set at the blades and stops moving water at low speed first, which is why an overheating engine often shows nothing at full throttle.

Before You Buy
- Verify your engine model or serial number before ordering
- Check the serial range — the Yamaha 8 HP and 15 HP listed above cover specific number blocks only

- Lubricate the impeller with soapy water or glycerine before fitting — never fit it dry
- Check the pump housing and wear plate for scoring while the pump is open
- 30-Day Easy Returns
- Free Worldwide Shipping
- OEM Quality Without the Markup
