It is lubricated with grease and supplied as a single unit for straightforward swap-in replacement when an existing cross bearing has worn out or is being serviced as part of a u-joint rebuild. As a direct equivalent to the original Mercury Marine part, it is intended to restore u-joint function to factory specification without modification to the surrounding driveline components. The alloy steel construction is matched to OEM material specification, and the bearing carries a limited warranty.

It is designated for use with Extreme Cables only, making it a specific replacement component rather than a universal fit for every shift cable setup. This screw plays a role in the shift slide assembly, where correct fit and secure engagement are essential for reliable gear selection and smooth shift operation. Given its small size and precise dimensions of 0.39 x 0.39 x 0.39 inches, it is manufactured to close tolerances so it seats properly within the shift slide hardware it is designed for. At 0.04 pounds, it is a lightweight hardware item intended to be installed as part of a shift cable or shift slide service, repair, or rebuild rather than sold as a standalone visible component. Because shift linkage hardware directly affects whether a drive shifts cleanly between gears, using the correct screw for an Extreme Cables application helps avoid improper engagement or premature wear at the shift slide interface.

The shift arm connects into the shift cable linkage and includes a pull handle for smooth, positive shift engagement. Its stainless steel construction resists corrosion in the marine environment, and the white finish matches common factory shift assembly colors. This is a universal fit part, making it a straightforward replacement across compatible shift cable setups rather than being limited to one specific model or year. The complete package includes one Sierra 18-2169 Shift Arm, ready to install in place of a worn, cracked, or broken original arm. Boat owners and marine techs use this part to restore reliable shifting when the factory shift arm has failed or become loose, without needing to replace the entire shift cable assembly.

Its metal, alloy steel construction is designed to withstand the vibration, torque, and harsh marine operating environment these drivetrain components see in regular service.

Shifting linkage cables like this one transmit the shift lever motion from the helm to the lower unit, so a worn, stretched, or corroded cable can cause slipping gears, delayed engagement, or an inability to shift at all. The 18-2245-1 restores precise, positive shift action so the drive engages forward, neutral, and reverse the way it was designed to. This assembly is built with a nylon and polyvinyl chloride (PVC) construction for corrosion resistance in the marine environment, and it is sized specifically for the 1988-1993 OMC Cobra (except King) application: a 68 inch wire with a 58 1\/2 inch jacket. It replaces OMC part number 987661, so it drops into the same shift cable routing and connection points as the original equipment cable it is designed to replace. Because OMC Cobra sterndrives were produced with both cone-clutch and non-cone-clutch shift mechanisms, and with a separate King Cobra variant, matching the correct part number matters: the 18-2245-1 is specifically for units without a cone clutch. If your Cobra sterndrive uses a cone clutch or is a King Cobra model, a different Sierra shift cable part number applies. Always confirm your drive's clutch type and model before ordering to be sure the wire and jacket lengths and the shift mechanism match your application.\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 18-2245-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Length:\u003c\/strong\u003e 68 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Length:\u003c\/strong\u003e 58 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Nylon, Polyvinyl Chloride (PVC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 987661\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e 1988-1993 OMC Cobra (except King), without cone clutch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1988-1993 OMC Cobra (except King), without cone clutch\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e987661\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2245-1 shift cable fit?\u003c\/strong\u003e The 18-2245-1 is designed for 1988-1993 OMC Cobra sterndrives, except the King Cobra, and only for units without a cone clutch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2245-1 the same as the OMC 987661 cable?\u003c\/strong\u003e Yes, the Sierra 18-2245-1 Shift Cable Assembly replaces OMC part number 987661 and is built to the same wire and jacket dimensions for a direct fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this cable work on a King Cobra?\u003c\/strong\u003e No. The 18-2245-1 is specifically for OMC Cobra units except the King Cobra; the King Cobra uses a different Sierra shift cable assembly, part number 18-2246, with a 59 inch wire.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long is the wire on the 18-2245-1 shift cable?\u003c\/strong\u003e The wire measures 68 inches on the Sierra 18-2245-1 Shift Cable Assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the jacket length of this shift cable?\u003c\/strong\u003e The jacket length on the 18-2245-1 is 58 1\/2 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this shift cable fit drives with a cone clutch?\u003c\/strong\u003e No, the 18-2245-1 is built for 1988-1993 OMC Cobra (except King) applications without a cone clutch; a cone-clutch equipped drive requires a different cable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-2245-1 shift cable made of?\u003c\/strong\u003e It is constructed of nylon and polyvinyl chloride (PVC) for durability in a marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2245-1 shift cable weigh?\u003c\/strong\u003e The 18-2245-1 Shift Cable Assembly weighs 1.35 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2245-1 an OEM part or aftermarket?\u003c\/strong\u003e It is a Sierra aftermarket shift cable assembly manufactured as a replacement for OMC part number 987661, built to match the original fit and function.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-2245-1?\u003c\/strong\u003e The order includes one complete Sierra 18-2245-1 Shift Cable Assembly, sized with a 68 inch wire and 58 1\/2 inch jacket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 18-2245-1 different from the 18-2246 shift cable?\u003c\/strong\u003e The 18-2245-1 fits 1988-1993 OMC Cobra (except King) units without a cone clutch and has a 68 inch wire, while the 18-2246 is for the King Cobra and has a 59 inch wire.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988105572571,"sku":"SIE-18-2245-1","price":134.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2245-1__52652.1739458589.500.750.jpg?v=1785189082"},{"product_id":"sierra-18-2172-engine-coupler-replaces-mercruiser-14505a2-fits-gm-v-6-v-8-305-350-cid","title":"Sierra 18-2172 Engine Coupler, Replaces 14505A2, for GM V6\/V8 Engines with Triangular 3-Bolt Coupler","description":"\u003cp\u003eThe Sierra 18-2172 Engine Coupler is a triangular, 3-bolt engine coupler built for GM V6 and V8 marine engines, excluding MC-I, Alpha, and Bravo drive applications.

Each package contains 25 complete kits, making it suited for marine service shops and dealers who need to keep lower shift cable repair parts in stock rather than ordering one job at a time. Each individual kit inside the package bundles the four components needed to service the lower shift cable connection at the stern drive: a shift cable bellows to seal the cable where it passes through the drive housing, a shift cable assembly, a shift slide and screw, and a shift cable end kit. Supplying these parts together lets a technician complete a full lower shift cable service in one pass instead of sourcing each piece separately. The shift cable bellows, shift cable assembly, and shift slide and screw each carry a stated OEM cross-reference number, so the kit can be matched directly against the equivalent Mercury Marine part numbers during a repair. Because the kit covers #1R, MR, Alpha, Alpha I, Gen II and Bravo drives, it applies across several generations of MerCruiser stern drive shift linkage.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\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 18-2600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Lower Shift Cable Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 25 kits per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Drives:\u003c\/strong\u003e #1R, MR, Alpha, Alpha I, Gen II, Bravo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.72 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999875112\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Shift Cable Bellows (18-2753-2), Shift Cable Assembly (18-2248), Shift Slide \u0026amp;

This bellows keeps water out of the u-joint and gimbal area while allowing the drive to pivot and steer, protecting the u-joint, gimbal bearing, and driveshaft from water intrusion and corrosion. It is a direct equivalent for the Mercury Marine OEM part 60932A4, so it installs using the same mounting points and hardware as the original bellows it replaces. The product ships as a single U-joint bellows and includes a clamp for installation. Sierra manufactures this part (produced by Teleflex Marine) to a round profile matching the original equipment shape, and it is sized specifically for the medium application used on TR\/TRS drives rather than the larger or smaller bellows used on other Mercruiser drive generations. Because stern drive bellows are wear items exposed to constant flexing, heat, and saltwater or freshwater immersion, replacing a cracked, torn, or hardened bellows before it fails is the standard way to prevent water from reaching the gimbal bearing, u-joints, and ultimately the engine. This bellows is sold under part number 18-2751 and should be matched to your drive's serial number range before ordering.\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 18-2751\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e U-Joint Bellows\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e U-Joint Bellows, Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.37 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999312921\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00030999312921\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercruiser Bellows\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Teleflex Marine\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercruiser TR\/TRS drives, S\/N 3377316 and up\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury Marine 60932A4\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2751 U-joint bellows fit?\u003c\/strong\u003e The 18-2751 is sized for Mercruiser TR\/TRS drives, serial number 3377316 and up, sealing the u-joint and gimbal area between the transom assembly and the drive unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2751 a direct replacement for Mercury Marine 60932A4?\u003c\/strong\u003e Yes, Sierra part 18-2751 replaces Mercury Marine OEM part 60932A4 and uses the same mounting configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the U-joint bellows weigh?\u003c\/strong\u003e The Sierra 18-2751 U-joint bellows weighs 1.37 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size bellows is this?\u003c\/strong\u003e This is the medium-size U-joint bellows in Sierra's 18-2751 lineup, matched specifically to TR\/TRS drive applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with part number 18-2751?\u003c\/strong\u003e The package includes one U-joint bellows and a clamp for installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the 18-2751 bellows?\u003c\/strong\u003e It has a round shape, matching the profile of the original equipment bellows on TR\/TRS drives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWho manufactures the 18-2751 bellows?\u003c\/strong\u003e It is a Sierra-branded part, manufactured by Teleflex Marine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does a stern drive u-joint bellows need to be replaced?\u003c\/strong\u003e The bellows on a TR\/TRS drive flexes constantly and is exposed to water, so it cracks or hardens over time; a failed bellows lets water reach the u-joints and gimbal bearing, which is why Sierra offers 18-2751 as a preventive replacement part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2751 fit all Mercruiser drives?\u003c\/strong\u003e No, this specific part number is matched to Mercruiser TR\/TRS drives with serial number 3377316 and up; other Mercruiser drive generations use different Sierra bellows part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2751?\u003c\/strong\u003e The UPC for the Sierra 18-2751 U-joint bellows is 030999312921.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-2751 is a genuine Sierra-branded U-joint bellows, manufactured by Teleflex Marine, not a generic aftermarket substitute.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988111470811,"sku":"SIE-18-2751","price":55.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Untitled-1__89356.1770739270.500.750.jpg?v=1785188911"},{"product_id":"sierra-18-2753-2-shift-cable-bellows-for-mercruiser-alpha-bravo-i-ii-iii-1-2-sterndrives-replaces-74639-clamp-included","title":"Sierra Shift Cable Bellows 18-2753-2, Black, Medium - Replaces Mercury Marine 74639, 74639A2","description":"\u003cp\u003eThe Sierra 18-2753-2 is a black, medium-size shift cable bellows designed to seal the point where the shift cable passes into the drive bell housing.
