It is engineered to meet or exceed OEM performance, supplying the hydraulic pressure needed to actuate the sterndrive's steering cylinder and deliver reliable, consistent steering response at the helm.\u003c\/p\u003e\u003cp\u003eThis pump is a bolt-on replacement designed to install using the same mounting points and drive configuration as the original equipment pump it replaces, so it drops into the existing power steering circuit without modification. It is finished in white and ships as a single unit ready for installation. Every Sierra power steering pump is backed by Sierra's industry leading warranty, giving boat owners confidence that a failed or worn original pump can be swapped for a unit built to the same standard.\u003c\/p\u003e\u003cp\u003eBecause steering response and safety depend on a properly functioning pump, replacing a worn, leaking, or noisy power steering pump with the 18-7508 restores factory-level steering feel on GM-powered MerCruiser MCM\/MIE sterndrive boats.\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 18-7508\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Engine Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 10.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 9.9 x 9.8 x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282287221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e MerCruiser MCM\/MIE GM V6 \u0026amp; V8 (283, 305 \u0026amp; 350 cid) engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMerCruiser MCM\/MIE sterndrives with GM V6 \u0026amp; V8 (283, 305 \u0026amp; 350 cid) engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e16792A39\u003c\/li\u003e\n\u003cli\u003e16792A33\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat boats and engines does the Sierra 18-7508 power steering pump fit?\u003c\/strong\u003e The Sierra 18-7508 is built for MerCruiser MCM\/MIE sterndrives powered by GM V6 and V8 engines in the 283, 305, and 350 cubic inch displacement range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-7508 replace?\u003c\/strong\u003e This pump replaces OEM numbers 16792A39 and 16792A33, so it can be used as a direct swap for either of those original part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7508 an OEM or aftermarket power steering pump?\u003c\/strong\u003e It is an aftermarket replacement pump manufactured by Sierra and built to meet or exceed the original MerCruiser OEM specification for these applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7508 power steering pump weigh?\u003c\/strong\u003e The pump weighs 10.18 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-7508 power steering pump?\u003c\/strong\u003e It is finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-7508?\u003c\/strong\u003e Each order includes one complete power steering pump, the Sierra 18-7508, ready to install.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7508 come with a warranty?\u003c\/strong\u003e Yes, the Sierra 18-7508 is backed by Sierra's industry leading warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of the 18-7508?\u003c\/strong\u003e The pump ships in packaging measuring 9.9 x 9.8 x 8 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-7508 work on GM V8 350 cid MerCruiser applications?\u003c\/strong\u003e Yes, the 283, 305, and 350 cid GM V6 \u0026amp; V8 MCM\/MIE applications are all covered by the Sierra 18-7508.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation of the 18-7508 straightforward for a DIY boat owner?\u003c\/strong\u003e The 18-7508 is designed as a direct replacement for the original MCM\/MIE power steering pump, so it mounts in the same location using the existing steering circuit connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my power steering pump needs replacing?\u003c\/strong\u003e Symptoms like stiff or inconsistent steering, pump noise, or fluid leaks on a MerCruiser MCM\/MIE GM V6 or V8 sterndrive typically indicate it is time to replace the pump with a unit like the Sierra 18-7508.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988386459867,"sku":"SIE-18-7508","price":637.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7508__50557.1753448931.500.750.jpg?v=1785188370","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7508-power-steering-pump-for-mercruiser-mcm-mie-gm-v6-v8-283-305-350-cid-replaces-16792a39","provider":"Good Vibes Marina","version":"1.0","type":"link"}
