It is built to restore a worn or leaking Mercarb carburetor to proper working order, replacing the internal wear components that typically fail with age and ethanol-blended fuel exposure. This kit is matched to MerCruiser carburetors within the model and serial number range 6229718-C856558, and services carburetors carrying Mercruiser Carb numbers 1389-8490A2 and 1389-9350A2. A matching float, Sierra 18-7202, is available as a companion part for these same applications, since the float is sold separately from the carburetor kit itself.\u003c\/p\u003e\u003cp\u003eBecause this kit is specifically designed for the older MerCarb 2-barrel carburetor with the bottom fill accelerator pump cavity, it will not correctly service later Mercarb carburetors that use a different accelerator pump cavity design, so confirming the accelerator pump cavity style before ordering is important. Components in the kit are precision made for a proper fit against the original carburetor bore and passages, helping restore consistent fuel metering and a reliable idle and throttle response after installation.\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 18-7097\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Carburetor Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Carburetor Model:\u003c\/strong\u003e M2\/Mercarb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercruiser Carb Numbers Serviced:\u003c\/strong\u003e 1389-8490A2, 1389-9350A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel and Serial Number Range:\u003c\/strong\u003e 6229718-C856558\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompanion Float Part Number:\u003c\/strong\u003e 18-7202\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccelerator Pump Cavity Design:\u003c\/strong\u003e Older MerCarb 2-barrel, bottom fill\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 3302-9437, MERCURY MARINE 3302-804845\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.26 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 7.2 x 6.4 x 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior\/Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999321183\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser M2\/Mercarb carburetors, model and serial number range 6229718-C856558\u003c\/li\u003e\n\u003cli\u003eOlder MerCarb 2-barrel carburetors with the bottom fill accelerator pump cavity, used on MerCruiser MCM 120, 140, 470, 185, 200 and 898 engines, 1983-86\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1389-8490A2\u003c\/li\u003e\n\u003cli\u003e1389-9350A2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7097 carburetor kit fit?\u003c\/strong\u003e The 18-7097 kit is designed for MerCruiser M2\/Mercarb two-barrel carburetors within model and serial number range 6229718-C856558, including those used on MerCruiser MCM 120, 140, 470, 185, 200 and 898 engines from 1983-86.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit work on any Mercarb carburetor?\u003c\/strong\u003e No. The 18-7097 kit is specifically built for the older MerCarb 2-barrel carburetor that has the bottom fill accelerator pump cavity, not later Mercarb designs with a different accelerator pump cavity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM Mercruiser carburetor numbers does 18-7097 service?\u003c\/strong\u003e This kit services carburetors identified by Mercruiser Carb numbers 1389-8490A2 and 1389-9350A2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there an OEM cross-reference for this Sierra kit?\u003c\/strong\u003e Yes, the Sierra 18-7097 carburetor kit cross-references to OEM part numbers 3302-9437 and Mercury Marine 3302-804845.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the kit include the float?\u003c\/strong\u003e No, the float is a separate part.
