Just bought a 96 seadoo sportster, took it on the lake at idle for a couple minutes then when I went to speed up white smoke came from the exhaust and after another minute it shut down. The next day I hooked it up to a hose and started it up, it ran at idle pretty well but after another 2 minutes in gear and sped a up a little it shut down again. The water coming from the exhaust when its running is very milky, anyone have any ideas on what's going on with here?

Sounds like the problem is lack of fuel (for some reason).
Have you checked the fuel shut-off valve, it might be turned off thus the engines can't get fuel. Or there may be some air leaks in the fuel lines and the engine fuel pumps cannot pump fuel due to sucking air.
It's pretty normal to discover some amount of oil in the exhaust, especially if the engine has been heavily lubricated recently using storage fogging oil. Keep an eye on the oil tank level b/c if there are oil system problems you might notice some oil has disappeared from the tank.

The fuel is on and it idles just fine with no hesitation. Its just when I put it in gear and rev it up that I get the problems.
Also...Are you supposed to cap the port on the back of the boat that you hook the hose into. I noticed the top one has a cap but not the one in the back

Yes, leave the back one open, it's an exit for most of the cooling water while operating in water.
I think you should check your fuel lines for an air leak, it's quite common and easy to have a slight leak at the water/fuel/filter separator cup due to the cup is plastic and there's an o-ring at the lip that might fail to seal. This cup screws onto it's base.
Otherwise you can remove the fuel line from the fuel pump and blow with low pressure air backwards toward the fuel tank. before doing this remove the gas cap to avoid pressurizing the fuel tank. You should hear the air bubbling from inside the fuel tank much like a fish tank air pump stone, while forcing air into the fuel line down low through the fuel pickup inside the tank. It should be easy to blow air and no air leaks on the way b/c air leaks will keep the engine from receiving fuel.
If the fuel lines are all air tight and fuel is available to pump from the tank, it's possible your carburetors are internally dirty and must be disassembled and cleaned.
