Figure 2 - HIN Format After August 1, 1984
"Boats manufactured or imported on or after August 1, 1984, also have a duplicate secondary HIN affixed somewhere on an unexposed location inside the boat or beneath a fitting or item of hardware. The purpose is to help authorities identify your boat if a thief or vandals remove or damage the primary HIN on the transom. It is illegal for anyone (manufacturer, dealer, distributor, or owner) to alter or remove a HIN without the express written authorization of the Commandant, U.S. Coast Guard."
According to this info call Hunter, maybe they can tell you where the second hull number is located to verify correct number. I suspect a phone call to Hunter could also help figure out the number based on hull number and model. I suspect Lee is correct that your boat is a 93 since they changed the model identification in 1995.
