Based on Mercury Marine's popular 115 FourStroke, the new 115 Pro XS four-stroke weighs 16 pounds less than the two-stroke it replaces. It weighs 18 pounds less than its nearest competing 115 and comes with the highest displacement (2.1 liters) for that size engine, which translates to quicker acceleration and a faster top-end speed, Mercury says. The outboard comes in 20- and 25-inch-shaft versions and features idle charge, providing 48 percent more battery charging at idle speed. The 115 Pro XS starts at $10,610.
