Maxum 2200SR hull ID question

[Latrobe Tom]

I just bought a 2004 Maxum 2200SR. When I checked the hull stamp the number ID information was clear but there was a second stamp on it "2200SR 2015". Does anyone know what this means? I know the hull number ends in 04 that is the year of the boat but the second stamp has me puzzled.

You'd have to provide a picture. "2200SR 2015" does't confirm to the HIN parameters. Is it cast into the gelcoat, or a sticker?
