I have a GFI outlet in the cockpit and it is exposed to the elements but waterproof (see below). You will want to use the outlet for stuff other than cooking on the swim deck so keep that in mind before placing it. What about moving your cooking station to the port side so the cord won't be exposed? Curious, how do you keep your NuWave cooker from sliding around? I can just see some jerk in a jet ski waking you and your breakfast going into the drink.
Another alternative is to use your gas grill to cook on. We used to have a gas Magma Marine Kettle Party Grill and you could remove the grill and there was a place to rest your pan so that it would be closer to the flame and wouldn't slide off when you got waked. We cooked many a breakfast of eggs and sausage links on that thing. I just Googled this set up and it appears Magma now has a variety of griddles specifically for using the party kettle as a stove top (see 2nd picture below). With the gas grill set up, you won't have to crank up the noisy gen to cook.
