WakeParts Registry is an identity index over EPA marine engine certification parts. Duplicate year and family filings for the same manufacturer part number collapse to one atom at /part/{brand-slug}/{part_number}.
REV A1
This is not a retailer, not a warranty, and not a fitment certificate. Fitment tables only appear when the D1 store actually has them. No maps.
Brand hubs require ≥ 50 distinct part numbers. Family hubs require ≥ 20 rows and ≥ 10 distinct PN. Filter URLs are noindex.
Change vs previous snapshot is shown on the same hub. History is not a URL farm. User reports (HTML/PDF) are on-demand and noindex.
