If your boat was made within the last 30 years then it should have a Hull ID Number (HIN) on the transom and somewhere inside the boat.
The first 3 characters of the HIN are known as the MIC and can be used to identify your manufacturer.
Take the MIC and enter it at this USCG site to find out more about a particular boat builder:
