Starting at $4,999, the two-passenger Sea-Doo Spark is the least expensive personal watercraft on the market. The Spark’s hull and deck are molded from a durable, lightweight composite dubbed Polytec, a mix of polypropylene with long-strand glass fibers. Polytec features a matte finish, a look Sea-Doo plays up with a choice of five colors, including orange crush (orange), bubble gum (magenta) and pineapple (yellow) along with a classic black and white. The deck is reinforced with an exoskeletonlike frame, which adds rigidity while reducing weight. In stock trim Sea-Doo forgoes a bow stowage compartment, giving you a good look at that exoskeleton’s futuristic design. Customer access points are minimal, but hull and deck can be unbolted in about 10 minutes, offering unprecedented access to the engine.
