The slim 2.6-liter six-cylinder in-line powerhead is amplified by a supercharger system that boosts performance across the rpm range. The high performance cylinder head features dual overhead camshafts for optimal combustion control and deep- breathing airflow all the way to 7000 rpm.
The long-bolt design clamps the cylinder head, cylinder block and lower crankcase together in a solid, stable unit to maximize durability.
The slim in-line powerhead contributes to a cowl profile that accommodates 26-inch center-to-center mounting on multi-engine transoms to facilitate installations on both new boats and repowers.
The Mercury Racing Advanced MidSection (AMS) isolates the powerhead from the transom to ensure running quality is smooth and quiet at all speeds.
Stainless-steel guide plates on the lower transom bracket that stabilize the engine for improved durability and steady handling at high speeds and in rough sea conditions.
Specific 400R engine mounts within the Mercury Racing Advanced MidSection (AMS) were selected for the perfect combination of handling and running quality.
A 6400-7000 rpm wide-open throttle operating range and a 1.75:1 gear ratio offer a wide window for propping options.
Standard electro-hydraulic power steering offers smooth, precise steering at all speeds. Mercury Digital Throttle and Shift (DTS) Zero Effort controls provide precise shifting action and instant response while eliminating cable rigging and maintenance.
