Things appear to be smooth sailing for Larsa Pippen and Marcus Jordan -- the couple couldn't get enough of each other while aboard a boat in Miami this week ... and we got the pics!!
Larsa and MJ were spotted cruising on a massive yacht and socializing with a handful of friends ... but made sure to get some private time during the outing -- which, naturally, involved a lot of PDA.
The couple cozied up on a sofa as they shared a few smooches and had a passionate chat .
