A lovely tune!! As you say better known to the public at large from Outlander. I think however to pipers it can never be anything else but the Skye Boat Song!!

Humbly, I would like to add some interesting information I’ve found on tratiditional tunes archives about the origin of this melody: Words to the tune were written by Sir Harold Boulton to an air collected by Miss Annie MacLeod (Lady Wilson) in the 1870's. It seems that Miss MacLeod was on a trip to the isle of Skye and was being rowed over Loch Coruisk (Coire Uisg, the 'Cauldron of Waters') when the rowers broke out into the Gaelic rowing song "Cuchag nan Craobh" (The Cuckoo in the Grove). A talented composer and singer, MacLeod remembered fragments of the song and fashioned them into an air which she set down in notation with the intentions of using it later in a book she was to co-author with Boulton. Sir Harold joined Miss MacLeod at Roshven House, Invernesshire, soon after to work on their book, by which time the whole group at the residence was humming the "scrap of chanty" collected by her, and he too soon began to work the air around in his imagination. It was he that transformed the words the group had been singing: Row us along, Ronald and John Over the sea to Roshven into: Over the sea to Skye and it was he who wrote additional lyrics in a Jacobite mold, introducing the heroic figures of Bonny Prince Charlie and Flora MacDonald. .
