Hello Ihuntalone, odds are you have a 175, the 150's had a sticker on the Limb that said (150). To tell for sure, you can measure the Thinnest part of the Limb. The 150's will measure (.235), and the 175's will measure (.290).
Also, the Havoc 150 used Cables that were Blue, and measured (13-1/8") long, the Havoc 175 had Black Cables and were (14-1/2") long. Both bows use the same string, Blue (31-1/2") long.
And yes, you can change a (150) to a (175) by installing (175) Limbs, and (14-1/2") Cables.
Good Hunting, Joe
