Sierra Power Pack 18-5887-1, Replaces 436367 584122, for Evinrude/Johnson V6 Optical Sensor Blue Sleeve

The Sierra 18-5887-1 Power Pack is an ignition power pack built for Evinrude/Johnson V6 outboard engines equipped with an optical sensor and a blue sleeve on the power pack. It is engineered to meet or exceed the quality of the original equipment part it replaces, using marine-grade materials and precision manufacturing for reliable ignition performance. This power pack is fit-specific: it is designed to be installed only on engines with the blue sleeve configuration and should not be used with a gray sleeved stator, since the two configurations are not interchangeable. The unit ships in white and includes one power pack per package. Buyers should confirm the sleeve color and sensor type on their existing power pack before ordering to ensure correct fitment, as installing the wrong version can result in improper ignition timing or a non-functioning system. Sierra manufactures this part to direct cross-reference with the original OEM numbers, making it a straightforward like-for-like replacement for V6 engines within this optical sensor and blue sleeve family.
