The trigger assembly works with the engine's ignition system to signal spark timing, and this unit is built for gasoline-fueled, freshwater-use outboard applications. It is constructed of durable aluminum for reliable performance in the marine engine environment.\u003c\/p\u003e\u003cp\u003eThis trigger assembly is compatible with 6 cylinder outboard engines and is rated up to 225 horsepower. It is designed as a mount-type trigger that installs directly onto the engine, and it serves as a Mercury Marine equivalent replacement part, cross-referencing to Mercury Marine part number 96455A9. Coverage spans several Mercury outboard engine families and serial number ranges, including the 105 JET, 115 6 cylinder, and V135 models, making it a straightforward replacement option when the original trigger assembly on these engines needs service.\u003c\/p\u003e\u003cp\u003eEach unit ships as a single trigger assembly, ready to install in place of a worn or failed factory trigger. Because outboard trigger assemblies are matched to specific engine serial number ranges, confirm your engine's serial number falls within the applicable range before ordering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
