The impeller is the core wear component of a marine water pump, drawing raw water through the pump housing to cool the engine and keep it running within safe operating temperatures. As a rubber-bladed rotor, it flexes with each rotation to move water continuously; over time and use, the rubber vanes wear, crack, or take a set, reducing flow and putting the engine at risk of overheating, so periodic replacement is a standard part of outboard maintenance.\u003c\/p\u003e\u003cp\u003eSierra manufactures this impeller to meet or exceed the performance of the original part it replaces, using materials and tolerances intended to hold up in continuous marine service. It is designed to fit engines rated at 70 horsepower for the 1991-95 model years within serial number range E138600-E345999, and 75 horsepower for the 1996-98 model years within the same serial number range E138600-E345999. Always confirm the engine's horsepower rating and serial number against these ranges before ordering, since impeller part numbers vary by model year and serial number on these engines.\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 18-8900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Impeller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Impeller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Engine Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Horsepower:\u003c\/strong\u003e 75 Horsepower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Equivalent Part Number:\u003c\/strong\u003e CHRYSLER FORCE 47-19453\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e70 HP, 1991-95, Serial No. E138600-E345999\u003c\/li\u003e\n\u003cli\u003e75 HP, 1996-98, Serial No. E138600-E345999\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCHRYSLER FORCE 47-19453\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-8900 impeller fit?\u003c\/strong\u003e It fits 70 horsepower outboards for the 1991-95 model years within serial number range E138600-E345999, and 75 horsepower outboards for the 1996-98 model years within that same serial number range E138600-E345999.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my engine's serial number is in the correct range?\u003c\/strong\u003e Check your outboard's serial number tag against the range E138600-E345999;
