They are non-marking, meaning they won't leave scuffs on your hull, and are generally more resistant to cuts, abrasions, and degradation from fuel or sun exposure.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eOEM vs. Aftermarket?\u003c\/summary\u003e\n  \u003cp\u003eThis listing is an aftermarket replacement (not OEM).
