Each kit contains two Sierra 18-5205 condensers (cross-referenced to OEM number 581419) and two Sierra 18-5141 contact sets, giving a technician or DIY boater everything needed to service both ignition points in one purchase instead of sourcing condensers and contact sets separately.\u003c\/p\u003e\u003cp\u003eThe kit is designed for Johnson\/Evinrude 9.9 HP, 15 HP, 35 HP, 40 HP, and 40 Comm outboard engines, and it replaces the original Johnson\/Evinrude tune-up kit numbered 172806. Because fit is specific to these engine and horsepower designations, confirming the OEM number against your outboard before ordering is recommended. Sierra manufactures each component in the kit to meet or exceed the performance of the original equipment part it replaces, so ignition timing and spark quality after installation match what the OEM kit delivered when new.\u003c\/p\u003e\u003cp\u003eAt 0.1 pounds, the kit ships as a compact parts set rather than a bulky assembly, making it easy to keep as a spare aboard the boat or in a service kit for scheduled maintenance.\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 18-5003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 172806\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e (2) Sierra 18-5205 Condensers, (2) Sierra 18-5141 Contact Sets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondenser OEM Number:\u003c\/strong\u003e 581419\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Johnson\/Evinrude 9.9 HP, 15 HP, 35 HP, 40 HP, 40 Comm outboard engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999318251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson\/Evinrude 9.9 HP outboard engines\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 15 HP outboard engines\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 35 HP outboard engines\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 40 HP outboard engines\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 40 Comm outboard engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e172806\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhich outboard engines is the Sierra 18-5003 tune-up kit designed for?\u003c\/strong\u003e The 18-5003 kit is designed for Johnson\/Evinrude 9.9 HP, 15 HP, 35 HP, 40 HP, and 40 Comm outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5003 tune-up kit include?\u003c\/strong\u003e Each 18-5003 kit contains two Sierra 18-5205 condensers and two Sierra 18-5141 contact sets, covering both ignition components needed for a full tune-up in one package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the Sierra 18-5003 replace?\u003c\/strong\u003e It replaces Johnson\/Evinrude OEM part number 172806.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the condenser in this kit a genuine Sierra part?\u003c\/strong\u003e Yes, the condensers included in the 18-5003 kit are genuine Sierra 18-5205 condensers, cross-referenced to OEM number 581419.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many contact sets and condensers come in one 18-5003 kit?\u003c\/strong\u003e Two of each: (2) Sierra 18-5141 contact sets and (2) Sierra 18-5205 condensers, enough to service both ignition points on the applicable outboard.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5003 kit fit a 25 HP or 50 HP Johnson\/Evinrude outboard?\u003c\/strong\u003e No, the 18-5003 kit is fit-specific to 9.9 HP, 15 HP, 35 HP, 40 HP, and 40 Comm Johnson\/Evinrude engines, so a 25 HP or 50 HP model is not covered;
