Start with the engine identity

  1. Match the manufacturer name exactly.
  2. Find the EPA family code on the engine label or documentation.
  3. Confirm the manufacturer part number in an official manual.
  4. Verify serial-range, year and configuration before buying or fitting anything.

Safety boundary: family membership is certification evidence only. It does not prove interchangeability, availability, price or vessel compatibility.
