Use the teleport and teleport yourself to a City (Bay Village, Kokkara, Korin Village and so on).
Talk with a Merchant like this one. (Every shop works)

Press Shop and then click one of the following buttons. The first one repairs one item, so you are supposed to click on your scouter. The second one repairs everything and is faster. (I'll recomend this button because you armor can be broken too!)
