It is a direct fit for 235 HP outboards from the 1979-1984 model years. Note that this engine application requires two Power Packs per engine, so buyers replacing a full ignition set should order two units. The Power Pack carries a machined exterior finish and is supplied as a single unit per package. Because it is a like-for-like replacement for the original OMC ignition module, installation follows the same mounting and wiring configuration as the factory part, without modification to the outboard's ignition harness. Sierra cross-references this Power Pack to a range of OEM and aftermarket part numbers, making it straightforward to confirm compatibility against an old or worn unit before ordering. This part is intended for buyers maintaining or restoring 235 HP Johnson and Evinrude outboards who need a reliable ignition Power Pack replacement.\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 18-5760-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Power Pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282392352\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e 235 HP outboards, 1979-1984\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Required:\u003c\/strong\u003e 2 Power Packs required per engine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e OMC 582138, 582400, 582556, 582642;
