It is used to reseal the transom assembly where the drive shaft housing passes through the boat's transom, replacing the water intake hose and hose clamps that seal this critical connection between the engine compartment and the outdrive. Keeping this seal in good condition helps prevent water intrusion into the boat and exhaust or coolant leakage at the transom, both common failure points as the original hoses and clamps age and harden.\u003c\/p\u003e\u003cp\u003eThis kit contains a water intake hose (Sierra 18-3602, O.E. 32-41725-33) along with two smaller hose clamps (Sierra 18-710-16-2) and one larger hose clamp (Sierra 18-710-24-2), giving the installer everything needed to reseal the water intake path in one purchase. It is sold and priced per package of 5 kits, which suits shops and repowers servicing multiple units or keeping stock on hand. The kit directly replaces OEM part 30-803099T1 and is designed to fit MerCruiser Alpha One Gen II drive systems.\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 18-8206-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Transom Seal Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e MerCruiser I\/O Drive System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e MerCruiser Alpha One Gen II\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 5 kits per package (priced per package)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Water Intake Hose (18-3602, O.E. 32-41725-33) x1, Hose Clamp (18-710-16-2) x2, Hose Clamp (18-710-24-2) x1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMerCruiser Alpha One Gen II\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e30-803099T1\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-8206-1 Transom Seal Kit fit?\u003c\/strong\u003e The 18-8206-1 kit is designed for MerCruiser Alpha One Gen II stern drive systems, sealing the transom area where the drive shaft housing passes through the boat's transom.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-8206-1 replace?\u003c\/strong\u003e It replaces OEM part number 30-803099T1, so any listing or parts diagram referencing that number matches the Sierra 18-8206-1 Transom Seal Kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the transom seal kit?\u003c\/strong\u003e The kit includes one water intake hose (Sierra 18-3602, O.E. 32-41725-33), two smaller hose clamps (Sierra 18-710-16-2), and one larger hose clamp (Sierra 18-710-24-2).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many kits come in one package?\u003c\/strong\u003e The 18-8206-1 is sold in a package of 5 kits and priced per package, not per individual kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the transom seal kit weigh?\u003c\/strong\u003e The Sierra 18-8206-1 Transom Seal Kit weighs 4.55 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-8206-1 is a genuine Sierra-branded transom seal kit manufactured as a direct replacement for MerCruiser Alpha One Gen II drives, not a generic clone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the Sierra 18-8206-1 manufactured?\u003c\/strong\u003e The transom seal kit is manufactured in China under the Sierra brand.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the transom seal need to be replaced?\u003c\/strong\u003e Over time the water intake hose and clamps in the transom assembly harden and crack, which can allow water intrusion or leaks at the transom on Alpha One Gen II drives; the 18-8206-1 kit provides fresh replacement hose and clamps for this repair.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the kit include the transom seal itself or just hoses and clamps?\u003c\/strong\u003e The 18-8206-1 package contains the water intake hose and its three hose clamps used to reseal this connection; it does not list a separate rubber transom gasket beyond these components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-8206-1 kit work on a Bravo or Alpha One Gen I drive?\u003c\/strong\u003e The 18-8206-1 Transom Seal Kit is specified for MerCruiser Alpha One Gen II drives; fitment for other drive generations is not stated for this part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the O.E.
