377 MAG Seacore Catalyst 320HP, engine only* Bravo configuration. Custom-built exclusively by MerCruiser in Stillwater, Oklahoma, this 320 HP powerhouse uses a longer stroke and a special roller tappet camshaft to create extra torque. What that means for the boater is better acceleration and quicker planing, particularly for heavier boats. The 377 MAG features a forged crankshaft and special pistons for the ultimate in durability. It is available with a variety of robust Bravo drive options. Like all our V8 Bravo Multi-Port Injection (MPI) sterndrive models, the 377 MAG is also available with optional Digital Throttle & Shift (DTS). DTS eliminates cable maintenance and provides consistent silky-smooth shifting. ** DTS SMARTCRAFT OPTIONAL. NEW CONTROLS & HARNESSES REQUIRED. MUST USE SMARTCRAFT GAUGES. AL RIGGING ACCESSORIES AND UPGRADE CHARGE ARE EXTRA FOR THIS APPLICATION. INSTALLATION MUST BE DONE BY A CERTIFIED DTS TECHNICIAN AS THE SOFTWARE IS ESSENTIAL TO THE DTS FUNCTIONALITY.
NOTE: Engines sold after Jan 1, 2010 require either ECT Catalyst or the old engine being replaced to be returned to Mercury per EPA 1068.240. Please call for details.
NOTE: CRATE CHARGE APPLICABLE (USD$300).
