It replaces OEM numbers 438529, 438531, and 434496, giving boat owners a straightforward way to restore power tilt and trim function without sourcing a discontinued original part. The motor is finished in white, uses a transom mount design, and is engineered for 2 stroke gasoline outboards, including salt water use where corrosion resistance matters most.\u003c\/p\u003e\u003cp\u003eEach unit ships as a single motor per package. Sierra builds this trim motor to meet or exceed the performance of the original equipment part it replaces, so fit and function match what the outboard was originally designed around. It is intended to bolt into the existing trim system on applicable Johnson and Evinrude outboards without modification, restoring reliable up and down trim and tilt operation.\u003c\/p\u003e\u003cp\u003eThis trim motor fits a specific range of Johnson\/Evinrude outboard horsepower and year combinations, so confirm the horsepower and model year listed below before ordering to make sure the 18-6780 is the correct match for your outboard.\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 18-6780\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.94 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 2 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Transom Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e Salt Water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282105136\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 438529, 438531, 434496\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson\/Evinrude 90, 115, 200, 225 HP (1991-Up)\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 120, 140 HP (1991-94)\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 130 HP (1995-Up)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e438529\u003c\/li\u003e\n\u003cli\u003e438531\u003c\/li\u003e\n\u003cli\u003e434496\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-6780 tilt and trim motor fit?\u003c\/strong\u003e The Sierra 18-6780 fits Johnson\/Evinrude outboards at 90, 115, 200, and 225 HP for 1991-Up, 120 and 140 HP for 1991-94, and 130 HP for 1995-Up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-6780 replace?\u003c\/strong\u003e It replaces OEM numbers 438529, 438531, and 434496 on applicable Johnson\/Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-6780 an original equipment part or aftermarket?\u003c\/strong\u003e It is an aftermarket replacement built by Sierra to meet or exceed the performance of the original 438529, 438531, and 434496 motors it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-6780 trim motor weigh?\u003c\/strong\u003e The Sierra 18-6780 tilt and trim motor weighs 2.94 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-6780 trim motor?\u003c\/strong\u003e It is finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-6780 suitable for salt water use?\u003c\/strong\u003e Yes, Sierra recommends the 18-6780 tilt and trim motor for salt water applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many motors come in the package?\u003c\/strong\u003e One Sierra 18-6780 tilt and trim motor ships per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of engine is the 18-6780 designed for?\u003c\/strong\u003e The 18-6780 is designed for 2 stroke gasoline outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 18-6780 trim motor mounted?\u003c\/strong\u003e It uses a transom mount configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-6780 fit a 130 HP Johnson\/Evinrude outboard?\u003c\/strong\u003e Yes, for the 1995-Up 130 HP Johnson\/Evinrude outboard the 18-6780 is a listed fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-6780 fit a 140 HP outboard from any model year?\u003c\/strong\u003e The 18-6780 covers the 140 HP Johnson\/Evinrude outboard for the 1991-94 model years specifically.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988359622875,"sku":"SIE-18-6780","price":195.77,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-6780__65443.1737882213.500.750.jpg?v=1785188008","url":"https:\/\/www.goodvibesmarina.com\/products\/tilt-and-trim-motor-for-johnson-evinrude-85-115-135-hp-v-4-outboards-replaces-omc-172543-motor-and-reservoir-sierra-18-6780","provider":"Good Vibes Marina","version":"1.0","type":"link"}
