WEEKEND WARRIOR. If you're an angler who prefers four-stroke technology or someone who wants a more advanced, refined and enjoyable ride from a performance engine your prayers are answered - the newest addition to the industry's most comprehensive lineup of performance outboards. These engines - equally superb on bass boats, multi-species boats, saltwater bay boats and performance pontoons - are pleasingly quiet and virtually vibration-free, despite their ability to rocket out of the hole and provide unequalled mid-range acceleration and top speed. If you're headed to a specific location and want to get there first, these are your engines - especially if you want to get there in style and comfort using state-of-the-art technology.
