Features

• Engine Details: Great for bass and multi-species fishing boats.
• Take it to the Limit: No outboard gets from zero to wide-open quicker than a Mercury Pro XS, now with V8 4.6-liter and V6 3.4-liter muscle. This is performance that will rocket your rig out of the hole and to the next hot spot in a blur. These Pro XS models feature generous displacement in a performance-tuned powerhead with a deep-breathing double-overhead-cam design and long-runner intake tract that delivers instant throttle response at any speed.
• Discover better boating: Active Trim by Mercury makes boating easier and more enjoyable by automatically trimming your engine. Active Trim simplifies boat operation while improving engine performance and decreasing fuel costs.
