The screw pairs with Sierra Gasket 18-4698, which creates the seal against the housing and should be replaced along with the screw each time the drain or fill plug is removed to prevent gear lube leaks. Installing a proper drain screw with a fresh gasket is a small but critical step in gearcase maintenance, since a worn or damaged sealing surface can allow lubricant to seep out or water to enter the housing, leading to costly internal damage. This part number is intended as a direct equivalent for the OEM numbers listed below, so it can be used as a drop-in replacement when servicing units originally fitted with those screws. Keeping a supply of these screws and matching gaskets on hand simplifies routine maintenance and helps ensure a proper, leak-free seal every time a lower unit is drained or refilled.\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 18-2371\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e M8-1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e Pack of 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Gasket:\u003c\/strong\u003e Sierra 18-4698\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282185541\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 688-45341-00-00, 688-45341-10-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e688-45341-00-00\u003c\/li\u003e\n\u003cli\u003e688-45341-10-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size is the Sierra 18-2371 drain screw?\u003c\/strong\u003e The Sierra 18-2371 drain screw has an M8-1.25 thread.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many screws come in a pack?\u003c\/strong\u003e Sierra 18-2371 is sold in a pack of 50 drain screws.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-2371 come with a gasket?\u003c\/strong\u003e No, the screw itself does not include a gasket, but it is designed to use Sierra Gasket 18-4698, which should be installed with it to create a proper seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-2371 replace?\u003c\/strong\u003e The 18-2371 drain screw replaces OEM numbers 688-45341-00-00 and 688-45341-10-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2371 drain screw weigh?\u003c\/strong\u003e Each unit is listed at 0.01 pounds, reflecting the small size of an individual drain screw.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this screw be used for both drain and fill ports?\u003c\/strong\u003e Yes, the Sierra 18-2371 is used as a drain and fill screw on lower unit and gearcase housings that use the M8-1.25 thread and match the listed OEM numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a new gasket required every time the drain screw is removed?\u003c\/strong\u003e It is recommended to replace the gasket, such as Sierra 18-4698, whenever the 18-2371 drain screw is removed to maintain a leak-free seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2371 an OEM or aftermarket part?\u003c\/strong\u003e The 18-2371 is a Sierra-brand replacement part manufactured as an equivalent to OEM numbers 688-45341-00-00 and 688-45341-10-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering this item?\u003c\/strong\u003e Ordering the Sierra 18-2371 provides 50 individual drain screws; the matching gasket, Sierra 18-4698, is a separate part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy buy drain screws in a pack of 50?\u003c\/strong\u003e A pack of 50 Sierra 18-2371 screws is intended for shops and technicians who regularly service lower units and need a ready supply of correctly sized drain and fill screws.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988105965787,"sku":"SIE-18-2371","price":9.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2371__28318.1558324186.500.750.jpg?v=1785329156"},{"product_id":"sierra-18-2378-magnetic-drain-fill-screw-lower-gearcase-plug-for-evinrude-outboards-replaces-omc-311598","title":"Sierra Magnetic Drain Screw 18-2378, Replaces 309243, for Cobra Drives \u0026 V-6 40-50HP (1989-97)","description":"\u003cp\u003eThe Sierra 18-2378 is a magnetic drain screw designed for gearcase drain and fill service on Cobra Drives \u0026amp; V-6 applications, 40-50HP (1989-97).

This set also fits 215E and 215H drive applications. It is designed to restore a proper seal at the outdrive housing during a rebuild or service job, preventing water intrusion and lubricant leakage that can lead to gear housing damage. As a direct cross-reference to Mercury Marine part numbers 27-54014A1 and 27-54014Q1, it allows technicians and boat owners to service their outdrive without hunting down original manufacturer parts. Every gasket in the set is sized and shaped to match the factory fit points on the applicable MerCruiser drive housing, so installation follows the same steps as the original equipment. Because outdrive housings vary between drive models and serial ranges, confirming your drive's serial number and check valve configuration before ordering helps ensure the correct gasket set is installed.

It seats under the drain and fill plugs to create a reliable seal against gear lube leakage, preventing seepage past the plug threads as the gearcase heats and cools through normal operation. Being plastic rather than metal, the washer resists corrosion in the wet, salt-exposed environment around a lower unit drain plug, and it is inexpensive enough to replace as a matter of routine every time the gear lube is changed, which is the standard practice for sealing washers of this type. This part is designed to be used with the Sierra 18-2387 drain screw, pairing the correct washer to the correct screw for a proper seal at the drain point. Because it directly replaces OEM number 311598, it is a straightforward swap for anyone servicing a gearcase that originally used that factory washer. Being sold in a pack of 5 lets a technician or boat owner keep spares on hand, since a fresh washer at every fluid change is the simplest way to avoid a plug that will not seal.\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 18-4248-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Drain\/Fill Plug Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e Pack of 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With:\u003c\/strong\u003e 18-2387 Drain Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 311598\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eDesigned for use with the Sierra 18-2387 drain screw at the gearcase drain\/fill point.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e311598\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-4248-9 washer made of?\u003c\/strong\u003e It is made of plastic, which resists corrosion better than a metal washer in the wet environment around a gearcase drain plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many washers come in a package of the 18-4248-9?\u003c\/strong\u003e The 18-4248-9 is sold in a package of 5 plastic drain\/fill plug washers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-4248-9 washer replace?\u003c\/strong\u003e This washer replaces OEM number 311598.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat drain screw is the 18-4248-9 washer used with?\u003c\/strong\u003e It is used with the Sierra 18-2387 drain screw to seal the gearcase drain\/fill point.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the 18-4248-9 washer with a different drain screw?\u003c\/strong\u003e The 18-4248-9 washer is specified for use with the 18-2387 drain screw; that is the pairing it is designed to seal against.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow often should the drain\/fill plug washer be replaced?\u003c\/strong\u003e A fresh washer like the Sierra 18-4248-9 is typically installed every time the gear lube is drained and refilled, since reusing an old sealing washer risks a leak at the plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-4248-9 an OEM or aftermarket part?\u003c\/strong\u003e The 18-4248-9 is a Sierra-brand replacement washer that cross-references to OEM number 311598, so it is an aftermarket equivalent rather than a factory-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-4248-9 washer weigh?\u003c\/strong\u003e The Sierra 18-4248-9 drain\/fill plug washer weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if I do not replace the drain plug washer?\u003c\/strong\u003e Reusing a worn washer under the drain or fill plug can allow gear lube to seep out or water to seep in, which is why a new 18-4248-9 washer is recommended at each service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-4248-9 washer sold individually or in a set?\u003c\/strong\u003e It is sold as a package of 5 washers, not individually.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988172026075,"sku":"SIE-18-4248-9","price":7.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-4248-9__15912.1737887344.500.750.jpg?v=1785329157"},{"product_id":"sierra-18-4255-e-tec-drain-screw-allan-head-replaces-oem-307551-for-evinrude-e-tec-outboards","title":"Sierra E-TEC Drain Screw 18-4255, Replaces 309243, Fits 40-50 HP Cobra Drives (1989-97)","description":"\u003cp\u003eThe Sierra E-TEC Drain Screw, part number 18-4255, is a replacement gearcase drain screw engineered for outboard motors using Cobra Drives rated 40-50 HP (1989-97).

This gasket seals the mating surfaces of the upper casing to help maintain proper lubrication levels and prevent water intrusion into the gearcase, both of which are essential to protecting internal gears and bearings from corrosion and premature wear. Installing a fresh gasket whenever the upper casing is opened for service, such as during a gear lube change, seal replacement, or gearcase inspection, helps ensure a reliable seal is restored rather than reusing a compressed or damaged original gasket. Sierra manufactures this gasket for the marine aftermarket as a direct fit for the Yamaha outboard gearcase and drive parts application it is designated for. Keeping a gasket like this on hand is useful for routine maintenance and repair work on outboard lower units, since a compromised gasket can lead to lubricant loss or water contamination that damages gearcase components.\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 18-99164\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Upper Unit Casing Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Yamaha Outboard Gearcase \u0026amp; Drive Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 4 x 4 x 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282385781\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha outboard gearcase and drive systems (upper unit casing)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99164 gasket used for?\u003c\/strong\u003e Sierra part number 18-99164 is an upper unit casing gasket used to seal the upper casing of a Yamaha outboard gearcase and drive system, helping keep gear lubricant in and water out.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99164 gasket fit Yamaha outboards?\u003c\/strong\u003e Yes, the 18-99164 upper unit casing gasket is designated for Yamaha outboard gearcase and drive parts applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99164 gasket weigh?\u003c\/strong\u003e The Sierra Upper Unit Casing Gasket, part number 18-99164, weighs 0.05 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of this gasket?\u003c\/strong\u003e The 18-99164 gasket ships in packaging measuring 4 x 4 x 0.5 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-99164 a genuine Sierra part number?\u003c\/strong\u003e Yes, 18-99164 is the Sierra manufacturer part number for this Upper Unit Casing Gasket, not a supplier or retailer code.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should the upper unit casing gasket be replaced?\u003c\/strong\u003e This gasket should be replaced any time the upper casing on the Yamaha outboard gearcase is opened for service, such as during a gear lube change or gearcase inspection, since a reused gasket may not seal properly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if the upper casing gasket fails or is not replaced?\u003c\/strong\u003e A worn or damaged upper unit casing gasket like 18-99164 can allow gear lubricant to leak out or water to enter the gearcase, both of which can lead to corrosion and damage to internal gears and bearings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering part 18-99164?\u003c\/strong\u003e Ordering Sierra 18-99164 includes one Upper Unit Casing Gasket sized for the Yamaha outboard gearcase upper casing application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-99164 gasket an OEM or aftermarket part?\u003c\/strong\u003e The 18-99164 Upper Unit Casing Gasket is manufactured by Sierra for the marine aftermarket as a replacement part for Yamaha outboard gearcase applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this gasket be reused after removal?\u003c\/strong\u003e No, gaskets such as the Sierra 18-99164 are designed for one-time use; once the upper casing is disassembled, a new gasket should be installed to ensure a proper seal.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988437676251,"sku":"SIE-18-99164","price":39.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-99164__35951.1739477163.500.750.jpg?v=1785188329"},{"product_id":"gearcase-drain-fill-screw-18-2375-for-mercury-30-40-50-60-hp-outboards-gear-oil-plug-mpn-10-02683","title":"EMP Drain Screw 10-02683 for Mercury Outboard Gearcase \u0026 Drive","description":"\u003cp\u003eThe EMP Drain Screw, part number 10-02683, is a replacement drain screw designed for Mercury outboard gearcase and drive applications.

At 0.08 pounds, it ships light and is inexpensive to keep on hand as a routine maintenance item any time the outdrive is separated from the transom assembly.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e EMP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 27-02386\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Outdrive Gasket Set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Drives:\u003c\/strong\u003e 1, R, MR, Alpha One (with exhaust tube)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 27-64818A3, 27-94996A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 840080450247\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Included:\u003c\/strong\u003e 1 set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercruiser 1, R, MR, Alpha One sterndrives with exhaust tube\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e27-64818A3\u003c\/li\u003e\n\u003cli\u003e27-94996A1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat drives does the EMP 27-02386 outdrive gasket set fit?\u003c\/strong\u003e It fits Mercruiser 1, R, MR, and Alpha One sterndrives equipped with an exhaust tube.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this the same as the Mercruiser OEM gasket set?\u003c\/strong\u003e Yes, EMP part 27-02386 is a direct equivalent to Mercruiser OEM gaskets 27-64818A3 and 27-94996A1, sold together as one complete set.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the gasket set weigh?\u003c\/strong\u003e The 27-02386 outdrive gasket set weighs 0.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in the kit?\u003c\/strong\u003e One complete set (quantity 1) is included, covering the gaskets needed for a single outdrive installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need this gasket set?\u003c\/strong\u003e It is used any time a Mercruiser 1, R, MR, or Alpha One sterndrive is removed and reinstalled, such as for gimbal bearing, U-joint, or bellows service, since the original gaskets should not be reused.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does 27-02386 cross-reference to?\u003c\/strong\u003e This set corresponds to Mercruiser OEM gaskets 27-64818A3 and 27-94996A1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this gasket set work on drives without an exhaust tube?\u003c\/strong\u003e The EMP 27-02386 set is specified for the 1, R, MR, and Alpha One drives that use an exhaust tube configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 27-02386 an EMP part or a Mercruiser part number?\u003c\/strong\u003e 27-02386 is the EMP part number for this gasket set; it is offered as an aftermarket equivalent to the Mercruiser OEM gaskets it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I reuse the old outdrive gaskets instead of buying this set?\u003c\/strong\u003e Gaskets are designed for one-time use, so a fresh set like the EMP 27-02386 is needed each time the outdrive is separated from the bell housing to ensure a proper seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this product?\u003c\/strong\u003e The EMP 27-02386 outdrive gasket set has UPC 840080450247.\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":48991283839195,"sku":"EMP-27-02386","price":8.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/EMP_27-02386_MerCruiser_Outdrive_Gasket_Kit__87168.1722504621.500.750.jpg?v=1785329111"},{"product_id":"gearcase-drain-and-fill-plug-washer-replaces-omc-311598-fits-evinrude-40-48-50-hp-1993-and-up","title":"EMP Drain\/Fill Plug Washer 27-00957-1, Replaces 311598, Fits Evinrude 40\/48\/50 HP w\/15 Inch Shaft (1993 and Up)","description":"\u003cp\u003eThis EMP Drain\/Fill Plug Washer, part number 27-00957-1, is a plastic gasket used to seal the drain and fill plug on Evinrude outboard gearcases.
