Thrust bearings absorb the axial load generated by the propeller shaft as it pushes against the gearcase during operation, keeping the shaft properly positioned and preventing excessive wear on surrounding gearcase components. As the gearcase turns power from the drive shaft into thrust at the propeller, this bearing manages the forward and reverse loading that would otherwise be transferred directly into the housing.\u003c\/p\u003e\u003cp\u003eThis part is built to the same fit and function as the original equipment it replaces, making it a straightforward drop-in choice when servicing or rebuilding an Evinrude outboard gearcase. Because thrust bearings see continuous load whenever the engine is in gear, they are a common wear item to inspect and replace during a gearcase overhaul, especially if you're already into the lower unit for a seal, bearing carrier, or gear set replacement.\u003c\/p\u003e\u003cp\u003eThe Sierra Thrust Bearing 18-1363 is compact and lightweight at 0.04 pounds, consistent with its role as a small internal gearcase component rather than an externally visible part.\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 18-1363\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Thrust Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Evinrude outboard gearcase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282243142\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-1363 thrust bearing do inside an outboard gearcase?\u003c\/strong\u003e It absorbs the axial (forward and reverse) load from the propeller shaft, keeping the shaft aligned and preventing that load from wearing directly on the gearcase housing. The Sierra Thrust Bearing 18-1363 is fitted into the gearcase to handle this thrust load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-1363 a genuine Sierra part or aftermarket?\u003c\/strong\u003e 18-1363 is Sierra's own part number for this thrust bearing, so it is sold as a genuine Sierra replacement part rather than a third-party aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-1363 thrust bearing weigh?\u003c\/strong\u003e The Sierra Thrust Bearing 18-1363 weighs 0.04 pounds, reflecting its size as a small internal gearcase bearing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard brand is the 18-1363 thrust bearing designed for?\u003c\/strong\u003e This thrust bearing is designed for Evinrude outboard gearcases, part number 18-1363.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should a thrust bearing like the 18-1363 be replaced?\u003c\/strong\u003e A thrust bearing typically warrants replacement any time a gearcase is opened for service and the bearing shows wear, pitting, or play, since it carries continuous load whenever the outboard is in gear. Many owners replace the 18-1363 proactively during a full gearcase rebuild.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I install the Sierra 18-1363 thrust bearing myself?\u003c\/strong\u003e Installing a gearcase thrust bearing requires disassembling the lower unit to access the propeller shaft and bearing carrier, so it is best done by someone comfortable with outboard gearcase service or a qualified marine mechanic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-1363 come with installation hardware or seals?\u003c\/strong\u003e The 18-1363 is the thrust bearing itself; the dossier does not list additional seals or hardware bundled with this part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the Sierra 18-1363 thrust bearing?\u003c\/strong\u003e The Sierra Thrust Bearing 18-1363 carries UPC 808282243142.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would my outboard need a new thrust bearing?\u003c\/strong\u003e Worn thrust bearings can allow excess play in the propeller shaft, leading to noise, vibration, or accelerated wear on other gearcase parts, which is why the 18-1363 is a common inspection point during gearcase service on Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-1363 the correct part number to search for this bearing?\u003c\/strong\u003e Yes, 18-1363 is the Sierra part number to reference when ordering this specific Evinrude outboard gearcase thrust bearing.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988087582939,"sku":"SIE-18-1363","price":11.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-1363_lg__59954.1558121941.500.750.jpg?v=1785329187","url":"https:\/\/www.goodvibesmarina.com\/products\/reverse-gear-thrust-bearing-18-1363-for-evinrude-johnson-outboard-gearcase-replaces-omc-332514","provider":"Good Vibes Marina","version":"1.0","type":"link"}
