It serves as the electronic control unit that manages spark timing for the ignition system, and it is engineered to meet or exceed the performance of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eThe switch box is housed in a durable plastic enclosure finished in silver, with a compact 5.5 x 5.25 x 3.5 inch footprint that fits into the same panel-mount location as the original unit. It uses a rear connector for wiring and is rated for 18 Amps with a 1-way circuit and a single switch position, matching the electrical demands of the outboard ignition systems it is designed to serve.\u003c\/p\u003e\u003cp\u003eThis switch box is a direct interchange for a wide range of OEM and aftermarket part numbers used across multiple outboard brands, including CDI, Chrysler\/Force\/US Marine, Mallory, and Mercury Marine (including Mercury Race Outboard and Mercury Sport Jet applications). This broad cross-reference coverage makes it a practical replacement option for boat owners and technicians servicing older ADI-equipped outboards where locating an exact OEM part can be difficult.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
