It is designed as part of a routine ignition tune-up, working alongside the correct condenser to keep the points-type ignition system firing reliably. The contact set is constructed of aluminum and stainless steel components for durability in a marine ignition environment.\u003c\/p\u003e\u003cp\u003eThis contact set is fit specific and applies to a range of Mercury\/Mariner outboard horsepower ratings across specific engine serial number ranges, including 3.9 HP, 4 HP, 6 HP, 7.5 HP, and 9.8 HP models. Buyers should confirm their outboard's serial number falls within the applicable range before ordering, since Mercury\/Mariner reused horsepower ratings across different production runs with different ignition components. The 18-5140 pairs with the Sierra 18-5212 condenser and is also available as part of the Sierra 18-5008 tune-up kit for engines in the matching serial number ranges.\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 18-5140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e Contact Set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999237019\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 contact set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury\/Mariner outboard, 3.9 HP, serial numbers 1655013 to 2498155\u003c\/li\u003e\n\u003cli\u003eMercury\/Mariner outboard, 4 HP, serial numbers 2498136 to 2693114\u003c\/li\u003e\n\u003cli\u003eMercury\/Mariner outboard, 6 HP, serial numbers 1610265 to 2529894\u003c\/li\u003e\n\u003cli\u003eMercury\/Mariner outboard, 7.5 HP, serial numbers 2529895 to 2721150\u003c\/li\u003e\n\u003cli\u003eMercury\/Mariner outboard, 9.8 HP, serial numbers 1865776 to 2708898\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 398-2202\u003c\/li\u003e\n\u003cli\u003eGLM 70170\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5140 contact set fit?\u003c\/strong\u003e It fits Mercury\/Mariner outboard motors rated 3.9 HP, 4 HP, 6 HP, 7.5 HP, and 9.8 HP within specific engine serial number ranges, such as 1655013 to 2498155 on the 3.9 HP and 1865776 to 2708898 on the 9.8 HP.
