Document cues that help confirm you’re on the right file

Coverage boundaries to keep in mind
The model line is presented as “MCM 3.0L (181 CID)” rather than a broader multi-displacement family, and the fit is anchored to 1998-and-newer usage. The page also notes that MerCruiser applications can vary by installation requirements, so matching by designation/displacement and the 1998+ gate is the primary inclusion signal presented here.
