THE H.O. SERIES. BLURRING THE LINE BETWEEN BOATING AND AVIATION. Want to push some limits? The H.O. High Output Series outboards push them just about as far as they can go – or the industry recommends. But they come with everything it takes to handle it. Like a beefed-up Lightning gearcase that withstands the higher torque and rpms. Special vacuum formed gears with super-pure, extra-tough metallurgy. And stiffer engine mounts for superior handling and control at high speeds. All performance, all the time. Right down to the tricked-out graphics. Which, of course, will be pretty much a blur anyway.
