Finished in white, it is supplied as a single unit ready for installation as a direct replacement for the Mercury Marine solenoids it is designed to replace. Solenoids like this one act as the electrical switch that allows a low-current signal, such as a key-start circuit, to engage a much higher-current circuit, a role that is essential to reliable engine starting and electrical system operation on the water. Because marine electrical components are exposed to vibration, moisture, and temperature swings, using a solenoid manufactured to original equipment quality standards helps ensure consistent, dependable performance. The Sierra 18-5802 is cataloged under Mercruiser solenoids and is cross-referenced to Mercury Marine part numbers 65057A1, 65057T1, 65057, and 54981, making it straightforward to identify as the correct replacement when an original part number is known. It ships as a single, complete solenoid with no additional components required beyond the part itself. Buyers should confirm their original part number against the replacement list below before ordering to ensure proper fit.\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 18-5802\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Solenoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercruiser Solenoids\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.71 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 8 x 6 x 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999237286\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e65057A1\u003c\/li\u003e\n\u003cli\u003e65057T1\u003c\/li\u003e\n\u003cli\u003e65057\u003c\/li\u003e\n\u003cli\u003e54981\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5802 solenoid replace?\u003c\/strong\u003e The Sierra 18-5802 is a direct cross-reference for Mercury Marine solenoid part numbers 65057A1, 65057T1, 65057, and 54981.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-5802 solenoid?\u003c\/strong\u003e It is finished in white, matching the original equipment appearance for the Mercury Marine solenoids it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5802 weigh?\u003c\/strong\u003e The Sierra 18-5802 solenoid weighs 0.71 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-5802 solenoid?\u003c\/strong\u003e Listed dimensions for the Sierra 18-5802 solenoid are 8 x 6 x 4 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5802 an OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-5802 is a Sierra-manufactured replacement solenoid engineered to meet or exceed original equipment quality, not a genuine Mercury Marine part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many solenoids come in the package?\u003c\/strong\u003e The Sierra 18-5802 ships as a single solenoid, one unit per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of equipment is the 18-5802 solenoid used with?\u003c\/strong\u003e Sierra catalogs the 18-5802 under Mercruiser solenoids.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if the 18-5802 is the correct replacement for my old solenoid?\u003c\/strong\u003e Check the part number on your existing solenoid against the Sierra 18-5802 cross-reference list: 65057A1, 65057T1, 65057, and 54981.

As the switching component between the ignition circuit and the starter motor, the solenoid carries the high-current load needed to engage the starter, and a worn or corroded unit is a common cause of a no-crank condition on these outboards. The 18-5879 is built with 100% copper windings for maximum magnetic pull strength, along with solid copper terminals that reduce voltage drop at the connection points for a stronger, more consistent start signal. A copper contact disc is used inside the unit for longer service life under repeated cranking cycles, and the brackets and canister are plated to resist corrosion, which matters on an outboard that is regularly exposed to salt water and engine-bay moisture. It is built to meet or exceed OEM specifications and is designed as a direct, OEM-interchangeable replacement, so no modification is required for installation. The solenoid uses a transom mount configuration and is rated for use with 2-stroke gasoline engines. Because outboard solenoids are engine- and model-specific, confirm your engine's horsepower and model year against the fitment list below before ordering to make sure the 18-5879 is the correct part

It weighs 0.696 pounds, matching the compact footprint expected in outboard engine compartments where mounting space is limited.
