The power pack is the core ignition control module that manages spark timing and delivery, and a failing unit is a common cause of hard starting, misfiring, stalling, or a complete no-spark condition on these outboards. Installing a fresh 18-99168 restores factory ignition function without the guesswork of troubleshooting an aging original unit.\u003c\/p\u003e\u003cp\u003eThis power pack is built to fit 3 cylinder Johnson\/Evinrude outboards rated 65, 70, and 75 HP from 1972-1978, as well as 6 cylinder Johnson\/Evinrude outboards rated 150, 175, 200, and 235 HP from 1976-1978. It is a direct cross-reference for multiple original Johnson\/Evinrude part numbers, so it can be used to replace an existing power pack without modification to the wiring harness or mounting.\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 18-99168\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Outboard Ignition Power Pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 Cylinder Fitment:\u003c\/strong\u003e 65, 70, 75 HP, 1972-1978\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6 Cylinder Fitment:\u003c\/strong\u003e 150, 175, 200, 235 HP, 1976-1978\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 581925, 582057, 581713, 581726, 581334, 581493, 581551, 581552\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eJohnson\/Evinrude 3 cylinder outboards: 65 HP, 70 HP, 75 HP (1972-1978)\u003c\/li\u003e\n\u003cli\u003eJohnson\/Evinrude 6 cylinder outboards: 150 HP, 175 HP, 200 HP, 235 HP (1976-1978)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e581925\u003c\/li\u003e\n\u003cli\u003e582057\u003c\/li\u003e\n\u003cli\u003e581713\u003c\/li\u003e\n\u003cli\u003e581726\u003c\/li\u003e\n\u003cli\u003e581334\u003c\/li\u003e\n\u003cli\u003e581493\u003c\/li\u003e\n\u003cli\u003e581551\u003c\/li\u003e\n\u003cli\u003e581552\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-99168 power pack fit?\u003c\/strong\u003e The Sierra 18-99168 fits Johnson\/Evinrude 3 cylinder outboards rated 65, 70, and 75 HP from 1972-1978, and Johnson\/Evinrude 6 cylinder outboards rated 150, 175, 200, and 235 HP from 1976-1978.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99168 replace my original Johnson\/Evinrude power pack?\u003c\/strong\u003e Yes, the Sierra 18-99168 cross-references to original Johnson\/Evinrude power pack numbers 581925, 582057, 581713, 581726, 581334, 581493, 581551, and 581552, so it is a direct replacement for any of those parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99168 power pack weigh?\u003c\/strong\u003e The Sierra 18-99168 power pack weighs 0.9 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the power pack made of?\u003c\/strong\u003e The Sierra 18-99168 power pack is constructed with rubber as part of its housing material.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this power pack work on a 4 or 5 cylinder Johnson\/Evinrude outboard?\u003c\/strong\u003e No, the Sierra 18-99168 is designed specifically for 3 cylinder (65, 70, 75 HP) and 6 cylinder (150, 175, 200, 235 HP) Johnson\/Evinrude outboards, not 4 or 5 cylinder models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a power pack do on an outboard motor?\u003c\/strong\u003e On these Johnson\/Evinrude outboards, the power pack controls spark timing and ignition delivery; a worn or failed unit like the original 581925 or 582057 often causes hard starting, misfiring, or stalling, which the Sierra 18-99168 is built to correct.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99168 a genuine OEM part or aftermarket?\u003c\/strong\u003e The 18-99168 is a Sierra-branded replacement part engineered to replace the original Johnson\/Evinrude power packs (including 581925, 582057, 581713, 581726, 581334, 581493, 581551, and 581552), rather than a part sourced directly from Johnson\/Evinrude.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat years of engines is the 18-99168 compatible with?\u003c\/strong\u003e For 3 cylinder 65, 70, and 75 HP engines, the Sierra 18-99168 covers model years 1972-1978.
