So, if you want to buy a setup that can be filled with a portable pump now and then plumbed in later here's what I'd do.
If you're a big surfer then get this:
If it's mostly for wakeboarding with a little bit of surfing get this and save $80:
Then get this integrated bow sac:
That will get you going but you certainly will not be able to fill either of those rear sacs full for wakeboarding. You'd be way too rear heavy. So, you'd probably just going to be limited to filling the rear 40-60% depending on if you can get a person or two to sit in the bow.
You will be able to fill that one side full plus the bow sac mostly or completely full for surfing. You'll have to play with how much to fill the front.
Get used to that for a while. If you want to go bigger then get this to put inside your ski locker:
That weight towards the front will allow you to add more to the rear sacs for wakeboarding. You still will likely not be able to fill them completely. Also, at this point (Possibly even before this point) you'll need to start considering a new prop since your takeoff speed will start to suffer.
Then you'll need to buy this (OJ 722 14.75 X 15.5 LC 1 1/8" 4-blade):
Also, at some point you may want something like this Fat Brick to be able to adjust for people weight or just to stick up in the nose of the boat when nobody wants to sit up there:
Somewhere during that evolution you're probably going to decide you either need to plumb in this stuff or get another portable pump because you're spending 30+ minutes setting up and 30+ minutes breaking it down every time you take the boat out. It's not cheap to buy all of the pumps, hose, fittings, switches and wiring and takes a lot of time. It also takes a lot of balls to drill a bunch of holes in the bottom of the hull for intake and the sides of the hull for overflow/drain. I don't have a firm number documented on what it took me.
As you can see you can spend quite a bit of money here.
