Sierra 18-3310 Water Pump Kit without Housing, Replaces Yamaha 6G5-W0078-01-00

The Sierra 18-3310 Water Pump Kit without Housing is a complete rebuild kit for the water pump on compatible Yamaha outboard engines, supplying every wear component needed to restore cooling system performance except the pump housing itself. The kit is built around a rubber impeller (Sierra 18-3071) along with the water pump gasket (Sierra 18-0244, O.E. 6E5-44315-00-00) and the mounting hardware required for reassembly, including four 90209-08M02-00 bolts and four 97395-08045-00-00 bolts. Because the housing is not included, this kit is intended for owners whose existing housing is still serviceable and who only need to replace the impeller, gasket, and fasteners -- Sierra also offers the 18-3311 kit, which is the same kit with the housing included, for buyers who need that component as well.

Each part in the kit is manufactured to meet or exceed the specifications of the original equipment it replaces, and Sierra backs its parts with the company's standard customer satisfaction warranty. The kit is finished in white and weighs 1.14 pounds as packaged. It is designed as a direct replacement for the OEM Yamaha water pump kit 6G5-W0078-01-00.
