BRUNSWICK MARINE POWER HIN FAQ
What does a BRUNSWICK MARINE POWER HIN look like?
It starts with the three characters "MPD" — the Manufacturer Identification Code the US Coast Guard assigned to BRUNSWICK MARINE POWER — followed by a 5-character hull serial and a 4-character date code, 12 characters total. BRUNSWICK MARINE POWER hulls (1988–2005) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits.
Is BRUNSWICK MARINE POWER still in business?
USCG records list BRUNSWICK MARINE POWER as out of business since 2005 (associated with BRUNSWICK FAMILY BOAT CO INC). That's common for older hulls — the HIN still decodes normally, and the out-of-business date helps date the boat and guides parts-hunting toward salvage and owner groups rather than a dealer network.
How do I decode the year on a BRUNSWICK MARINE POWER HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. BRUNSWICK MARINE POWER hulls (1988–2005) all use the current HIN format: a month letter (A=January…L=December), a certification-year digit, then two model-year digits. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
