How a MARINE HYDRO BOATS HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example ZMH45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | ZMH | Identifies MARINE HYDRO BOATS, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | MARINE HYDRO BOATS's own production number for the specific hull (the letters I, O, Q are never used). |
| 9 | Certification month | D | Month built — A=January … L=December (D = April). |
| 10 | Certification year | 4 | Last digit of the certification year. |
| 11–12 | Model year | 24 | The boat’s model year. |

MARINE HYDRO BOATS HIN FAQ
What does a MARINE HYDRO BOATS HIN look like?
It starts with the three characters "ZMH" — the Manufacturer Identification Code the US Coast Guard assigned to MARINE HYDRO BOATS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. MARINE HYDRO BOATS built hulls across both HIN eras (1975–1992): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format. The decoder handles all three.
Is MARINE HYDRO BOATS still in business?
USCG records list MARINE HYDRO BOATS as out of business since 1992. 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 MARINE HYDRO BOATS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. MARINE HYDRO BOATS built hulls across both HIN eras (1975–1992): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format. The decoder handles all three. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
Where is the HIN on a MARINE HYDRO BOATS boat?
On the outside upper-starboard (right) corner of the transom, within two inches of the top — required by 33 CFR 181.29. Since August 1984 an identical duplicate HIN is also molded into an unexposed interior location as an anti-theft measure. Both should match the title, registration, and insurance card exactly.
Is the "ZMH" MIC the same as a MARINE HYDRO BOATS serial number?
No. "ZMH" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies MARINE HYDRO BOATS. The hull serial number is characters 4–8: MARINE HYDRO BOATS's own production number for that specific boat (the letters I, O, and Q are never used). The full 12-character HIN combines the MIC, the serial, and the date code.
Can a MARINE HYDRO BOATS HIN tell me the exact model?
Not on its own. A HIN encodes the builder, hull serial, certification month/year, and model year — not the model name or length. Match the decoded year and serial against MARINE HYDRO BOATS records, the title, or a marine survey to confirm the exact model and configuration.
