As the shaft that connects the outboard's lower unit gearcase to the propeller, it transmits rotational power from the forward and reverse gear set to the prop, so its dimensional accuracy and finish directly affect smooth power transfer and gearcase alignment. The shaft carries a machined exterior finish for consistent fit against the gear set and clutch components it works alongside in the lower unit.\u003c\/p\u003e\u003cp\u003eThis part is built for Evinrude 25D, 40, 48, and 50 HP (2 Cylinder) outboards across the model years listed below. Always confirm your outboard's horsepower rating, model year, and cylinder configuration against the fitment table before ordering, since Sierra assigns different prop shaft part numbers to other Evinrude horsepower ranges and years.\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 18-2288\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Prop Shaft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.92 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282236052\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEvinrude 25D, 1989-95, ALL models\u003c\/li\u003e\n\u003cli\u003eEvinrude 40 HP, 1989-97, ALL models\u003c\/li\u003e\n\u003cli\u003eEvinrude 48 HP, 1989-96, ALL models\u003c\/li\u003e\n\u003cli\u003eEvinrude 50 HP (2 Cyl.), 1989-97\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat outboards does the Sierra 18-2288 prop shaft fit?\u003c\/strong\u003e The 18-2288 fits Evinrude 25D outboards from 1989-95, Evinrude 40 HP outboards from 1989-97, Evinrude 48 HP outboards from 1989-96, and Evinrude 50 HP 2 Cylinder outboards from 1989-97, all model configurations listed as ALL for those horsepower and year combinations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there an OEM cross-reference number for this prop shaft?\u003c\/strong\u003e No separate OEM cross-reference or replaces number is listed for this part; 18-2288 is the part number to use when ordering or verifying fit against your outboard's parts diagram.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2288 prop shaft weigh?\u003c\/strong\u003e The Sierra 18-2288 prop shaft weighs 2.92 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the 18-2288 prop shaft have?\u003c\/strong\u003e This prop shaft has a machined exterior finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2288 fit a 50 HP Evinrude with a 3 cylinder engine?\u003c\/strong\u003e No. The 18-2288 is specified for the 50 HP 2 Cylinder Evinrude configuration from 1989-97; a 3 cylinder 50 HP Evinrude from 1997 uses a different Sierra prop shaft part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2288 come with the gear set or clutch?\u003c\/strong\u003e The 18-2288 listing covers the prop shaft only; the forward gear, reverse gear, and clutch used alongside it in the lower unit are separate, individually numbered components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-2288 prop shaft?\u003c\/strong\u003e The listed product dimensions for the Sierra 18-2288 are 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2288 a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-2288 is a genuine Sierra-branded prop shaft, identified by Sierra part number 18-2288 and UPC 808282236052.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the 18-2288 on a 40 HP Evinrude from the 1980s?\u003c\/strong\u003e Only if the engine falls within the 1989-97 model years listed for the 40 HP fitment; 40 HP Evinrude outboards built in 1984-88 use a different prop shaft part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is in the box with the 18-2288 prop shaft?\u003c\/strong\u003e The 18-2288 ships as a single machined prop shaft component.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988105736411,"sku":"SIE-18-2288","price":117.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2288_lg__65344.1558123964.500.750.jpg?v=1785188306","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2288-propeller-shaft-for-evinrude-outboard-replaces-wm-118-2288-machined-prop-shaft","provider":"Good Vibes Marina","version":"1.0","type":"link"}
