This electronic ignition component controls spark timing and delivery to the engine's cylinders, and it is a direct functional replacement for the original equipment power pack used on 90, 110, and 115 HP engines. The unit has no RPM limit, so it will not artificially cap engine speed the way some aftermarket ignition components do.\u003c\/p\u003e\u003cp\u003eEach package contains one power pack. Because the covered engines use two power packs working together, two units (two separate packages) are required for a complete ignition system replacement -- if only one power pack has failed, the second can typically remain in service, but many installers replace both at the same time to ensure matched performance and to avoid a second failure shortly after the repair.\u003c\/p\u003e\u003cp\u003eThe Sierra 18-99249 is intended as a drop-in replacement for the OEM power pack, using the original mounting and wiring configuration on the engines it fits, and is backed by a 2-year manufacturer warranty.\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 18-99249\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Evinrude Outboard Power Packs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinders:\u003c\/strong\u003e 4-Cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPM Limit:\u003c\/strong\u003e None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Contents:\u003c\/strong\u003e One power pack (two required per engine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2-year manufacturer warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.56 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 5 x 4 x 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282396596\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson, Evinrude, and OMC Sea Drive outboards, 90 HP, 110 HP, and 115 HP, 1985-1986 (two power packs required per engine)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e18-5783\u003c\/li\u003e\n\u003cli\u003e4-5783\u003c\/li\u003e\n\u003cli\u003e582811\u003c\/li\u003e\n\u003cli\u003e763794\u003c\/li\u003e\n\u003cli\u003e9-25005\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-99249 power pack fit?\u003c\/strong\u003e The Sierra 18-99249 fits Johnson, Evinrude, and OMC Sea Drive outboards rated at 90 HP, 110 HP, and 115 HP, 1985-1986.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there an RPM limit on this power pack?\u003c\/strong\u003e No, the Sierra 18-99249 has no RPM limit, unlike some aftermarket power packs that cap engine speed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to buy more than one power pack?\u003c\/strong\u003e Yes.
