The rectifier converts the AC output from the outboard's stator into DC current to charge the battery, making it a critical component for reliable electrical system operation. It is built as a drop-in replacement covering a wide range of outboard applications, cross-referencing to numerous OEM part numbers so boaters can find the correct replacement using either the original engine manufacturer's number or the Sierra part number 18-99429.\u003c\/p\u003e\u003cp\u003eThis rectifier is compatible with 2 cylinder outboards from 9.9 to 50 HP, 3 cylinder outboards from 50 to 90 HP, and 4 cylinder outboards from 100 to 140 HP. It is a straightforward bolt-in replacement for a failed or underperforming rectifier, restoring proper charging output and preventing battery drain or overcharging caused by a degraded unit. Compact and lightweight at 0.1 pounds, it is sized to fit within the existing mounting location on the outboard's electrical panel without modification.\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 18-99429\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 20 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 2 x 2 x 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282394608\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Chrysler Outboard Electrical System\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2 cylinder outboards, 9.9 to 50 HP, 1975-1992\u003c\/li\u003e\n\u003cli\u003e3 cylinder outboards, 50 to 90 HP, 1975-1985\u003c\/li\u003e\n\u003cli\u003e4 cylinder outboards, 100 to 140 HP, 1976-1989\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e474470\u003c\/li\u003e\n\u003cli\u003e650450\u003c\/li\u003e\n\u003cli\u003e510450-1\u003c\/li\u003e\n\u003cli\u003e617450\u003c\/li\u003e\n\u003cli\u003e87-F650450\u003c\/li\u003e\n\u003cli\u003eFA617450\u003c\/li\u003e\n\u003cli\u003eFA650450\u003c\/li\u003e\n\u003cli\u003eF475470\u003c\/li\u003e\n\u003cli\u003eF510450\u003c\/li\u003e\n\u003cli\u003eF510450-1\u003c\/li\u003e\n\u003cli\u003eF404470\u003c\/li\u003e\n\u003cli\u003eF404470-1\u003c\/li\u003e\n\u003cli\u003eF617450\u003c\/li\u003e\n\u003cli\u003eF650450\u003c\/li\u003e\n\u003cli\u003eF684450\u003c\/li\u003e\n\u003cli\u003eF684458\u003c\/li\u003e\n\u003cli\u003eFK650450\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-99429 rectifier do?\u003c\/strong\u003e It converts the AC output from an outboard engine's stator into DC current to charge the battery, and is rated for 20 amp output.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard engines is the 18-99429 rectifier compatible with?\u003c\/strong\u003e It fits 2 cylinder outboards from 9.9 to 50 HP built 1975-1992, 3 cylinder outboards from 50 to 90 HP built 1975-1985, and 4 cylinder outboards from 100 to 140 HP built 1976-1989.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99429 a direct OEM replacement?\u003c\/strong\u003e Yes, part number 18-99429 is designed as a direct replacement, cross-referencing to OEM numbers including 474470, 650450, 617450, and 510450-1 among others.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does 18-99429 replace?\u003c\/strong\u003e It replaces 474470, 650450, 510450-1, 617450, 87-F650450, FA617450, FA650450, F475470, F510450, F510450-1, F404470, F404470-1, F617450, F650450, F684450, F684458, and FK650450.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99429 rectifier weigh?\u003c\/strong\u003e The Sierra 18-99429 rectifier weighs 0.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-99429 rectifier?\u003c\/strong\u003e It measures approximately 2 x 2 x 2 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this rectifier work on a 3 cylinder outboard?\u003c\/strong\u003e Yes, the 18-99429 covers 3 cylinder outboards from 50 to 90 HP built 1975-1985.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99429 rectifier require any modification to install?\u003c\/strong\u003e No, it is a bolt-in replacement sized to fit the existing rectifier mounting location on compatible outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a mounting bracket or hardware included with the 18-99429?\u003c\/strong\u003e The rectifier itself is the unit supplied under part number 18-99429; no additional components beyond the rectifier are specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the amperage rating of the Sierra 18-99429?\u003c\/strong\u003e The 18-99429 is rated at 20 amps.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988443967707,"sku":"SIE-18-99429","price":55.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-152-9209_lg__49596.1558111722.500.750.jpg?v=1785188083","url":"https:\/\/www.goodvibesmarina.com\/products\/universal-rectifier-20-amp-for-chrysler-force-sears-gamefinder-outboard-replaces-650450-617450-fits-9-9-140-hp-1975-1992-sierra-18-99429","provider":"Good Vibes Marina","version":"1.0","type":"link"}
