Levitation costs money (and I dont like wasting money). Either to buy a good scroll which doesnt take forever and lasts the time it needs to or to train a lot.
Water Walking is the same thing.
Anyways, thanks
Effe Tei and Almsivi Intervention from Sadrith Mora. Got it.
EDIT: Oh, and if you want you can upload that mod of yours
At the Balmora Guild of Mages you can buy a water walking spell very cheaply; it costs 5 or 6 magicka and lasts like 60 seconds. That's long enough so that you only need to cast it once or twice in order to run from the island to the mainland. It's also a simple enough spell that by the time you make it over to that part of the island, it should be a breeze to cast, even for a warrior or stealth type character.
An addendum... you must not have played very far into the game if you're worried about money. I spent 10,000 coins just the other day on a play-through for training, bribing, and armor repairs over the course of a few hours, and still had over 100,000 left. I never even sell anything that's ebony/adamantium/glass/dwemer/daedric, either, so all my cash is from "grunt level" items. Meldor over in Balmora has enough weapons and armor to outfit all of Balmora three times over, if it were to scale. That's a lot of resting in order for his cash supply to respawn...
