It's just like glass boats. The more HP you put on the back, the more likely you are to have a gel coat crack. The more HP you put on an aluminum boat, the more likely you are to crack a weld. Not to mention if they offered it with a 200, and then come with a glass boat rated for a 200, the price is going to be so close most will buy the glass boat. If they were not going to build glass boats a 200 + HP rated aluminum would make way more sense.
