Water Pump Impeller Minor Repair Kit 394711 for Johnson Evinrude 8 9.9 15 HP
Water Pump Impeller Minor Repair Kit 394711 for Johnson Evinrude 8 9.9 15 HP
Product Overview
Water pump impeller minor repair kit for Johnson and Evinrude 8 HP, 9.9 HP and 15 HP outboards, supplied as 1 impeller, 2 O-ring seals and 1 drive key. It replaces 394711, 0394711, 391388, 777801 and Sierra 18-3327, and crosses to GLM 12050 and Mallory 9-48201. This is the reduced kit: the housing, wear plate and cup are not included, so it is the right choice when the pump body is still good and only the rubber and seals have gone hard. If the liner is scored, buy the kit with housing instead, because a new impeller in a worn housing will not hold prime at idle.
