I have a 1990 Hydra-Sport 185 DV Fish and Ski and it has two different copacity plates on it. One say max 4 people and is a sticker. The other is made of hard plastic and say max of 6 people. Does anyone know how to find out wich one is right? There is plenty of seating for six people. I am not to much worried about weight because it is usually just me, my two kids and there friends knee boarding. Thanks for the help.
