This seal is used where the factory parts diagram calls for the exact seal number in the driveshaft housing, lower unit, bottom cowl, or water-passage area. It helps maintain proper cooling-water routing through the housing connection and should be replaced whenever the related sealing joint is opened or the original seal is hardened, cracked, flattened, or leaking.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Mercury Marine factory OEM sealing component.\u003c\/li\u003e\n\u003cli\u003eUsed in select vintage Mercury outboard and MerCruiser sterndrive cooling-water passage locations.\u003c\/li\u003e\n\u003cli\u003eCommonly associated with driveshaft housing, lower-unit, bottom-cowl, and water-transfer sealing points.\u003c\/li\u003e\n\u003cli\u003eHelps seal cooling-water pathways between connected housings.\u003c\/li\u003e\n\u003cli\u003eImportant during water pump, impeller, lower-unit, or driveshaft housing service.\u003c\/li\u003e\n\u003cli\u003eShould be matched by exact Mercury part number and factory diagram location before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eApplication Compatibility\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eCommon where-used application groups include select Mercury and MerCruiser models by serial number and diagram location, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury 65 HP\u003c\/strong\u003e outboards, serial range \u003cstrong\u003e1765044 through 2119748\u003c\/strong\u003e, where specified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury 90 HP\u003c\/strong\u003e outboards, serial range \u003cstrong\u003e1766824 through 1869775\u003c\/strong\u003e, where specified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercury 100 HP and 110 HP\u003c\/strong\u003e outboards, serial range \u003cstrong\u003e1768404 through 2318585\u003c\/strong\u003e, where specified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMerCruiser 120 \/ 140 \/ 165\u003c\/strong\u003e sterndrive applications where specified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMerCruiser 470 \/ 485\u003c\/strong\u003e applications where specified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMerCruiser 225-S \/ 228 \/ 233 \/ 250 \/ 260 \/ 888 \/ 898\u003c\/strong\u003e applications where specified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMerCruiser Model 60 Renault 68\u003c\/strong\u003e applications where specified\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUse this seal only where the Mercury\/MerCruiser parts diagram specifically calls for the exact part number.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSerial Number Fitment Notice\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eConfirm fitment by engine or drive serial number, housing style, cooling-water passage layout, and exact Mercury\/MerCruiser parts diagram before ordering. Early Mercury outboards and MerCruiser sterndrives used many similar-looking seals across driveshaft housings, lower units, water pump areas, and transom-related passages, so model family alone is not enough to confirm fitment.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eWhen This Part Needs Replacement\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eReplace this seal if there is visible water leakage at the driveshaft housing connection, cooling-water leakage near the lower unit, a damaged or flattened old seal, or if the seal is disturbed during impeller, water pump, lower-unit, or driveshaft housing service. Old rubber seals often lose compression and may not reseal properly after disassembly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eClean both mating surfaces before installing the new seal. Remove old rubber, salt buildup, corrosion residue, grease, and debris without gouging the housing surfaces. Inspect the water tube, water pump housing, driveshaft housing, lower-unit mating face, fasteners, and related gaskets while the assembly is apart. Install the seal in the exact orientation shown in the Mercury\/MerCruiser service diagram and follow the correct tightening sequence for the specific model.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eExact Mercury\/MerCruiser part number needed before publishing\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eVerify any older, superseded, or replacement numbers by serial number and factory diagram before substitution.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eCooling-water seals in vintage outboards and early MerCruiser drives should be replaced when the joint is opened, even if the old seal looks usable.
