It is built to restore proper cooling flow when an impeller and its related wear components have worn down, cracked, or hardened with age. The kit brings together every small part typically consumed during a water pump service into a single purchase, so the job can be done in one pass rather than sourcing individual pieces separately.\u003c\/p\u003e\u003cp\u003eInside the kit you will find the 18-0244 water pump gasket, four 18-0256 bolts, the 18-3071 impeller, the 18-3302 impeller key, the 18-3333 insert cup, the 18-3345 wear plate, and two O-rings (18-7483 and 18-7485). Because the housing is not included, this kit is intended for applications where the existing housing is still in good condition and only the internal wear components need replacing.\u003c\/p\u003e\u003cp\u003eThe Sierra 18-3395 directly replaces the Yamaha 61A-W0078-01-00 water pump kit.
