However, if you're unfamiliar with outboard ignition systems or uncomfortable working with electrical components, we recommend professional installation to ensure safety and proper function.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How does this aftermarket CDI compare to the Yamaha OEM unit?\u003c\/strong\u003e\u003cbr\u003e\nA: This listing is an aftermarket replacement part (not an OEM component).
