How many people? I'm no engineer, but, If we assume an average of up to 250 lbs. per person (always overdesign!), and we assume a maximum of, say, four people, that's a total of 5,100 lbs. concentrated in an area that is 7'x 7'(49 square feet). So, your load is 104 lbs. per square foot, or 8.67 lbs per square inch, as I figure it. Depending upon where the tub is placed in the deck (forward, back, left side, right side, centered), as well as what structural material you're using (I'm assuming wood, since you haven't mentioned any steel shapes), that could work. Of course, you also have to consider forces generated by "wave" motion and people moving in the tub (maybe moving quite a bit vigorously, too), but, at 8.67 lbs. per square inch, that shouldn't be a problem, I would think.
