The solenoid switches the high-amperage starter circuit when the ignition key is engaged, using a low-current signal from the ignition switch to close the internal contacts and send full battery power to the starter motor. It is built with a metal housing finished in black and is designed for wall mounting in the engine compartment, matching the physical footprint and terminal layout of the original Mercury unit it replaces.\u003c\/p\u003e\u003cp\u003eThis solenoid is application-specific to the fitment listed below, including engines fitted with a 5\/16-18 inch starter terminal and either 1 Ram Trim or 3 Ram Trim configurations. Because Sierra manufactures this part to original equipment specifications, it installs using the factory mounting points and wiring without modification. Boat owners and marine technicians use the 18-5834 as a like-for-like swap when an original Mercury starter solenoid fails or shows signs of a weak or intermittent starter engagement.\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 18-5834\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Starter Solenoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Wall Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 4.2 x 2.9 x 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.76 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282105990\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Arco SW109, GLM 72500, Mallory 9-15117, Mercury 89-817109A2, 89-817109A1, Mercury Sport Jet 817109A2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 100 HP 4 Cyl.
