The kit includes the pump housing along with the internal components needed to restore proper cooling water circulation, helping protect the powerhead from overheating damage caused by a worn or failed impeller housing. Sierra formulates the impeller compound in each kit based on the size and application of the pump, and the remaining kit components are built to meet or exceed original equipment specifications for reliable, long-term performance.\u003c\/p\u003e\u003cp\u003eThis kit is constructed from cast iron and stainless steel for durability in a saltwater and freshwater marine environment. It ships as a complete kit rather than a single component, so installers replacing a worn pump housing have the parts needed for the job in one package, including a housing bolt (O.E. #97095-08045-00, qty. 4).\u003c\/p\u003e\u003cp\u003eThe 18-3412 kit is designed to fit Yamaha 9.9 HP (1996-09) and 15 HP (1996-09) outboards, as well as Yamaha F9.9 (2005-06), F15 (1998-05), and T9.9 (2005-06) models.
