Magic Johnson's having the time of his life on his annual summer yacht vacation, gassing up the jet ski and hitting the beautiful Ionian Sea off the coast of Greece ... and boy, was he flyin'!
The NBA legend made his name on land, but turned into a bit of a water sports athlete on Thursday ... posting video -- wearing a life jacket (safety first) -- ripping around on a white and black jet ski.
You can see Johnson was all smiles as he sent it, full throttle, amidst the gorgeous scenery.
"I got my jet ski on for a few hours this morning in Myrtos Bay on Kefalonia Island, Greece," the 63-year-old said.
