The performance pontoon era didn't take flight right away though. In the late 1990s, more than 90 percent of pontoons sold were still the traditional two-tube variety, with horsepower averaging 25 to 50, one-third of today's power. The round tubes themselves were typically 21 inches in diameter, limiting their flotation and, thus, a boat's maximum rated horsepower. In Y2K, Odyssey's engineers, experimenting with ways to change the landscape, perfected a 23-inch-diameter tube, which later would grow to 25 inches. They welded strips of 1.5-inch angled aluminum to the tubes — lifting strakes. On the underside of the deck they crafted aluminum sheets to cover up the cross members and fasteners — maybe not the first to do so, but this version was curved into radiused underbellies. Then, along the St. Joseph River near Elkhart, Indiana, with local media and radar guns on the scene, the first Odyssey with twin outboards (Evinrude 250s) reached 81 mph. A pontoon!
