When I bought mine it had some minor cracks in the windscreen where it is perforated for the screws. I was told the newer models have a rubber sleeve around the perforations and do not crack as easily.
Your friend having a 2004 I imagine he has the rubber sleeves, the crack might of resulted from someone applying undue pressure.
Notwithstanding, I would talk with the dealer that sold it to you if it was not a private sale and maybe try to get a hold of Neil or Bud at Cigarette and have your friend explain his plight.
I ordered one from Phil Lipshutz who sold me our Tiger to replace the crack one but since he needed the current windscreen to make the holes I will replace it next winter when the boat is down there.
Here is a pic of where it crack around the screws on mine, about 3-4 of the 6 or 8 screw holes are cracked. BTW Phil being a very good dealer was taking good care of me on the price for the new windscreen. He is excellent to deal with.
