The two gleefully zoomed on top of the water, enjoying a beach vacation the way any other family members would.
In the video, obtained exclusively by "Good Morning America," the two climbed out of the water and Omer Bhatti leaned over to Jackson, telling him something cameras didn't pick up.
"He wants to go again," Jackson said.
Increasing attention is being paid to Bhatti, now a 25-year-old aspiring rapper from Oslo, Norway, as questions swirl about the nature of his relationship with the King of Pop.
Jackson had been known to take up close friendship with children in the past, even bringing them along on his world tours. But none of those other children got a front row seat to Jackson's memorial service, dressed like Jackson's own brothers and sat with the family.
In pictures from the 1990s, Bhatti bears a resemblance to Jackson and not only because of their similarity in clothing. He also, more strikingly, seems to share features with Jackson's youngest son, Prince Michael II, 7, also known as Blanket.
Bhatti's mother Pia Bhatti, a former Jackson nanny, has denied that her son is Michael Jackson's son, but there are plenty of people who believe the contrary.
Jackson's father Joe Jackson is recently admitted that his most famous son may have four -- not three -- children.
"I knew he had another son, yes, I did," Joe Jackson said last week in an interview with TV One. "He looks like a Jackson, he can dance like a Jackson. This boy is fantastic dancer -- matter of fact, he teaches dance."
After the Jet-Sskiing, the video shows the duo of Jackson and Bhatti prepping for a parasailing trip and the soaring above the water. Jackson even took off his trademark fedora, saying later, "I wanted to see if I could hold onto my hat."
In a separate clip, Jackson can be seen introducing Bhatti to Nelson Mandela.
Jackson's inner circle at the time even questioned the superstar on whether Bhatti was just a close friend or a substitute for the children he did not yet have. Former Jackson friend Marc Schaffel said Jackson denied rumors that Bhatti was his son.
"Michael had told me very specifically to my face -- and I have no reason to believe he was lying to me at the time -- that that story was not true," Schaffel told "Good Morning America."
Schaffel speculated that Joe Jackson's comments about Bhatti indicate he may be looking to work with the young man in future business ventures.
"I definitely think he has his eye on Omer to do that, and if it's to launch his new venture, his new business label, I think he is actually looking at Omer to do that," he said.
Bhatti has said he and his parents met Jackson in Tunisia in 1996. The boy obviously idolized Jackson and could even moonwalk.
He went to live with Jackson at his Neverland Ranch and was there in 2003 with authorities raided the compound looking for evidence related to Jackson's molestation charges.
"He adored Michael, he looked up to him, he respected him, he admired him," Schaffel said. "I know that people for many years -- we didn't call him Omer, we called him little Michael."
In Vienna earlier this month, Jackson's brother Jermaine Jackson said Bhatti would be welcomed into the family, if he's proven a Jackson.
