It is designed for Bravo and inboard drives fitted with a brass pump body, covering units with serial number 0M100001 and above, as well as MCM 45L MPI and 2000 and newer MCM V-6 and V-8 (305, 350 and 496 cid) engines equipped with the brass sea water pump. The impeller is the wear component inside the raw water pump that circulates cooling water through the engine, and it should be replaced on a regular service interval or whenever cooling performance drops, since a worn or cracked impeller can lead to overheating.\u003c\/p\u003e\u003cp\u003eThis kit includes the impeller along with the matching gasket needed for the reinstall, so the pump housing can be resealed properly during the service. The brass construction and round shape match the original equipment brass pump design, making this a straightforward, direct-fit service part rather than a full pump housing replacement. Sierra manufactures this part to meet or exceed the performance of the original equipment component it replaces, and it is built for the demands of marine cooling systems.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-3016-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Impeller Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Impeller and gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.27 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282199937\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser Bravo and inboard engines with a brass pump body, serial number 0M100001 and above\u003c\/li\u003e\n\u003cli\u003eMerCruiser MCM 45L MPI\u003c\/li\u003e\n\u003cli\u003e2000 and newer MerCruiser V-6 and V-8 (305, 350 and 496 cid) engines equipped with the brass sea water pump\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-3016-1 impeller kit fit?\u003c\/strong\u003e The 18-3016-1 kit fits MerCruiser Bravo and inboard drives equipped with a brass pump body, serial number 0M100001 and above, as well as MCM 45L MPI and 2000 and newer MCM V-6 and V-8 (305, 350 and 496 cid) engines that use the brass sea water pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit include a gasket?\u003c\/strong\u003e Yes, the Sierra 18-3016-1 Impeller Kit includes the impeller along with the matching gasket needed to reseal the pump housing during installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-3016-1 impeller made from?\u003c\/strong\u003e This is a brass impeller kit, with a round-shaped impeller matching the original equipment brass pump design.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3016-1 impeller kit weigh?\u003c\/strong\u003e The Sierra 18-3016-1 Impeller Kit weighs 0.27 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this impeller work on a plastic pump body?\u003c\/strong\u003e No. The 18-3016-1 is designated for brass pump body applications;
