I am building a freeride superjet. i ride inland lakes. my question is should i install a scupper valve? i am going to be running dual cooloing and i am going to use the bilge line for a waterline so i will not have the stock bilge. i was going to just put dual bilges in. if i did a scupper i would still have a bilges. i do hang out on the lake at let it float sometimes. so let me know what you guys think. looking for all the info i can get on them
