WINNEBAGO POWER PRODS HIN FAQ
What does a WINNEBAGO POWER PRODS HIN look like?

Is WINNEBAGO POWER PRODS still in business?
USCG records list WINNEBAGO POWER PRODS as out of business since 1983. 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.

Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
