Water Pump Impeller Kit 47-16154-3 369-65021-1 for Mercury Tohatsu 2 3.5 HP Outboard
Water Pump Impeller Kit 47-16154-3 369-65021-1 for Mercury Tohatsu 2 3.5 HP Outboard
Product Overview
Water pump repair kit for Mercury 2 to 3.5 HP, Tohatsu and Nissan 2.5 and 3.5 HP and Johnson Evinrude 3.5 HP outboards, with a 33.6 mm six blade impeller, 14.35 mm high, 10.4 mm hub, supplied with a housing gasket, a plate gasket and a drive key, replacing 47-16154-3, 369-65021-1 and 18-3098.
This is the complete pump kit for the smallest four stroke and two stroke motors, not just the impeller. The two gaskets and the key are included because on these little pumps the housing gasket and the plate gasket are what fail first, and neither is reusable once the pump has been apart.
The 33.6 mm diameter is the small body used on the 2 to 3.5 HP range. Check the hub and the key, then check the stainless plate for scoring, because a scored plate will not seal against a new gasket and the pump will pull air instead of water.
