It is built for 2, 3, and 4 cylinder outboard and SportJet engines that use oil injection, covering model years 1990 through 1999. An oil warning module of this type monitors the oil injection system and signals an alert if the system detects a low oil condition, helping protect the engine from running with inadequate lubrication.\u003c\/p\u003e\u003cp\u003eThe module has a metal housing for durability in a marine engine compartment and is compact enough to fit into existing wiring and mounting locations on covered engines. It ships as a single unit and is identified for ordering purposes by Sierra part number 18-99411.\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 18-99411\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine Brand:\u003c\/strong\u003e Mercury\/Mariner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 2\/3\/4-cylinder 2-stroke outboard and SportJet engines with oil injection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Years:\u003c\/strong\u003e 1990-1999\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 2 x 4 x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282394424\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury\/Mariner 2\/3\/4-cylinder 2-stroke outboard and SportJet engines with oil injection, 1990-1999\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhich outboard engines fit the Sierra 18-99411 oil warning module?\u003c\/strong\u003e This module fits Mercury\/Mariner 2\/3\/4-cylinder 2-stroke outboard and SportJet engines equipped with oil injection, for model years 1990 through 1999.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does an oil warning module do?\u003c\/strong\u003e An oil warning module monitors the oil injection system on a 2-stroke outboard and triggers a warning signal if the system detects a low oil condition, which helps prevent engine damage from inadequate lubrication.
