You can find all the Marmalade Boy English Dub at Veoh just type in Marmalade Boy English Dub and set the search function to English audio, worldwide subs, and 20-60 minutes and they will show up for you.
I would add the links here for you in this thread myself but it has 76 episodes hope this helps.
