you will be buying the boat as the factory built it in '03. the dealer nor the factory are obligated to do any changes because this was how the boat came from the factory. the dealer and factory are only going to fix what breaks that is covered by warranty. you can ask/pay the dealer to make modifications like the inner hull drain for you or do them yourself , but the things we have done they do not h a v e to do. the factory has taken some of our ideas and added them on newer models ,but they are not gonna give these to you for your '03 unless you pay extra or negoiate them in you purchase of the boat.
this not the answer you wanted to hear i'm sure ,but this is how i have had to do things since my first one in '01.
heck i love doing all that stuff myself. the more i do the more i learn and the better prepared for the unexpected i'll be whether in the back yard or miles offshore
you got a brand new boat, get out there and enjoy it and tag along with us as we keep making them better
