It serves as the electronic ignition control component in the engine's ignition system, replacing the original factory power pack when it fails or wears out. This power pack is compatible with 85, 115, 135 and 140 HP Johnson\/Evinrude 4 cylinder outboards from 1973-1977, making it a straightforward swap-in solution for boat owners servicing these engines. It cross-references directly to the OEM power pack numbers used on these engines, so it can be ordered using either the Sierra part number or any of the original Johnson\/Evinrude part numbers it replaces. At 0.9 pounds, it is a compact component that mounts within the outboard's ignition circuit. Boat owners and marine technicians use this part when troubleshooting ignition failure, intermittent spark, or a no-start condition traced to a failed power pack on a 4 cylinder Johnson\/Evinrude outboard. Always confirm the specific engine model and HP rating against the part number 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 18-99169\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Ignition Power Pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engines:\u003c\/strong\u003e Johnson\/Evinrude 4 cylinder outboards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Horsepower:\u003c\/strong\u003e 85, 115, 135, 140 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Years:\u003c\/strong\u003e 1973-1977\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 581311, 581731, 581709, 582056, 581895\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude 4 cylinder outboards, 85, 115, 135 and 140 HP, 1973-1977\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e581311\u003c\/li\u003e\n\u003cli\u003e581731\u003c\/li\u003e\n\u003cli\u003e581709\u003c\/li\u003e\n\u003cli\u003e582056\u003c\/li\u003e\n\u003cli\u003e581895\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-99169 power pack do?\u003c\/strong\u003e It functions as the ignition power pack for Johnson\/Evinrude 4 cylinder outboard engines, controlling the electronic ignition system so the engine fires correctly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich engines fit part number 18-99169?\u003c\/strong\u003e Johnson\/Evinrude 4 cylinder outboards rated 85, 115, 135 and 140 HP from 1973-1977 use the 18-99169 power pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-99169 a direct replacement for my factory power pack?\u003c\/strong\u003e Yes, the Sierra 18-99169 cross-references to OEM power pack numbers 581311, 581731, 581709, 582056 and 581895, so it is a direct replacement on the Johnson\/Evinrude engines that used those factory parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat horsepower ratings does this power pack cover?\u003c\/strong\u003e The 18-99169 covers 85, 115, 135 and 140 HP Johnson\/Evinrude 4 cylinder outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat model years is the 18-99169 designed for?\u003c\/strong\u003e This power pack is designed for the 1973-1977 model years of the compatible Johnson\/Evinrude 4 cylinder engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99169 power pack weigh?\u003c\/strong\u003e It weighs 0.9 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does this cross-reference?\u003c\/strong\u003e Part 18-99169 cross-references OEM numbers 581311, 581731, 581709, 582056 and 581895.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I install the 18-99169 power pack myself?\u003c\/strong\u003e The 18-99169 is designed as a direct swap for the original Johnson\/Evinrude power pack on compatible engines, so it can be installed by anyone comfortable working on the outboard's ignition wiring;

It serves as the ignition control module that manages spark timing and delivery to the engine, a critical component for reliable starting and running. This switch box is designed to fit 4 cylinder Mercury\/Mariner outboards rated at 50, 65, 80, and 85 HP, as well as 6 cylinder Mercury\/Mariner outboards rated at 90, 100, 115, 125, 135, 140, and 150 HP. The housing is constructed of plastic and uses a spade terminal connection with a plug-in connector type, allowing it to interface with the factory wiring harness on applicable engines. It operates with a normally open contact and an ON-OFF operation mode, and is rated for a 1 kilovolt operating voltage with a 5 milliamp current rating. The unit measures 7 x 5 x 3 inches and weighs 1.8 pounds. Because ignition switch boxes are engine-specific, boat owners replacing a failed or intermittent ignition component should confirm their engine's cylinder count and horsepower rating against the fitment listed below before ordering.
