From UFO Parasail & Adventures in Maui “340 of them to be exact 🐎😎 A couple of DPH and DPI outdrives lined up for the fleet. Our vessels are I/O, meaning an inboard engine is mounted inside the boat while a steerable drive unit (pictured here) sits on the outside. Together, they deliver the ultimate performance and handling—perfect for parasailing.”
