It is built for drives designated 1, R, MR, and Alpha 1 with exhaust tube, and is used any time the outdrive is separated from the transom assembly, such as during gimbal bearing, u-joint, or bell housing service. The set contains five individual pieces: an 18-2743 outdrive gasket, an 18-2840 bell housing gasket, and three O-rings (18-7117, 18-7153, and 18-7170), so the technician has every sealing component needed for the job in one package rather than sourcing each part separately. The components are supplied as a display pack with a plastic material composition. Using a complete matched gasket set like the 18-2619-1, rather than reusing old gaskets or mixing in generic parts, helps ensure a proper seal against water intrusion and exhaust leakage at the outdrive-to-transom joint. The 18-2619-1 cross-references directly to the OEM Mercury\/MerCruiser part numbers below, so it is a direct fit replacement for the original equipment set on applicable drives.\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 18-2619-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Outdrive Gasket Set (Display Pack)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Contents:\u003c\/strong\u003e 18-2743 Outdrive Gasket, 18-2840 Bell Housing Gasket, 18-7117 O-Ring, 18-7153 O-Ring, 18-7170 O-Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\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 808282120207\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e MerCruiser 1, R, MR, Alpha 1 with exhaust tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 27-64818A3, 27-94996A1, 27-94996Q2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMerCruiser 1, R, MR, Alpha 1 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\u003cli\u003e27-94996Q2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2619-1 outdrive gasket set include?\u003c\/strong\u003e The 18-2619-1 set includes an 18-2743 outdrive gasket, an 18-2840 bell housing gasket, and three O-rings (18-7117, 18-7153, and 18-7170), for a total of five sealing components in one package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich drives does the 18-2619-1 gasket set fit?\u003c\/strong\u003e This Sierra gasket set is designated for MerCruiser 1, R, MR, and Alpha 1 outdrives equipped with an exhaust tube.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does 18-2619-1 replace?\u003c\/strong\u003e The Sierra 18-2619-1 outdrive gasket set replaces OEM numbers 27-64818A3, 27-94996A1, and 27-94996Q2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2619-1 outdrive gasket set weigh?\u003c\/strong\u003e It weighs 0.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a bell housing gasket included in this kit?\u003c\/strong\u003e Yes, the 18-2619-1 set includes an 18-2840 bell housing gasket along with the outdrive gasket and three O-rings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat O-rings come in the Sierra 18-2619-1 kit?\u003c\/strong\u003e Three O-rings are included: 18-7117, 18-7153, and 18-7170.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material are the gaskets and O-rings made of?\u003c\/strong\u003e The components in the 18-2619-1 set are made of plastic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2619-1 the correct gasket set for an Alpha 1 outdrive?\u003c\/strong\u003e Yes, the 18-2619-1 set is specified for MerCruiser Alpha 1 outdrives, in addition to the 1, R, and MR drives, when equipped with an exhaust tube.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many pieces are in the 18-2619-1 outdrive gasket set?\u003c\/strong\u003e The kit contains 5 individual pieces: one outdrive gasket, one bell housing gasket, and three O-rings, packaged as a single display pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2619-1 gasket set?\u003c\/strong\u003e The UPC for this Sierra outdrive gasket set is 808282120207.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2619-1 set work on drives without an exhaust tube?\u003c\/strong\u003e The 18-2619-1 gasket set is specified for MerCruiser 1, R, MR, and Alpha 1 drives with exhaust tube;
