The white shrouded housing encloses the internal contacts to help shield them from moisture, salt spray, and debris in the engine compartment, while the panel mount design allows it to install into the same relay location as the original part. It is built as a three-terminal, quick-connect relay with a normally open contact configuration and nickel iron alloy contacts for consistent switching performance under repeated trim and tilt cycling.\u003c\/p\u003e\u003cp\u003eThis relay is engineered to meet or exceed the specifications of the original equipment part it replaces, and it is interchangeable with a number of OEM and aftermarket cross-reference numbers, making it a straightforward replacement for boat owners who need to restore trim function without waiting on an OEM-only part. It fits Mercury 100 HP 4 cylinder outboards equipped with 1 Ram Trim and a 5\/16-18 starter terminal.\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 18-5849\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Shrouded Trim Relay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Quick Connect\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Nickel Iron Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally Open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Panel Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Terminals:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.6 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury 100 HP 4 Cylinder outboards with 1 Ram Trim and 5\/16-18 starter terminal\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCDI 852-9819\u003c\/li\u003e\n\u003cli\u003eChrysler\/Force\/US Marine 828151\u003c\/li\u003e\n\u003cli\u003eChrysler\/Force\/US Marine 828151A1\u003c\/li\u003e\n\u003cli\u003eMallory 9-15210\u003c\/li\u003e\n\u003cli\u003eMercruiser Stern Drive 882751A1\u003c\/li\u003e\n\u003cli\u003eMercury Marine 828151\u003c\/li\u003e\n\u003cli\u003eMercury Marine 828151A1\u003c\/li\u003e\n\u003cli\u003eMercury Marine 882751A1\u003c\/li\u003e\n\u003cli\u003eMercury Marine 882751A2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5849 relay do?\u003c\/strong\u003e The Sierra 18-5849 is a shrouded trim relay that controls the power trim and tilt circuit on applicable outboard engines, switching power to the trim motor when the operator raises or lowers the drive.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-5849 fit my Mercury outboard?\u003c\/strong\u003e The 18-5849 fits Mercury 100 HP 4 cylinder outboards equipped with 1 Ram Trim and a 5\/16-18 starter terminal;
