A 4.6-liter V8 powerhead is naturally aspirated and features deep-breathing double overhead cam/four-valve architecture with a short-runner intake manifold mated to a cold-air induction system.
An 11:1 compression ratio boosts torque output while the 7000 RPM redline extends the power curve. A dynamic oil pickup system is designed to maintain critical engine oil pressure under high-G loads.
A cut-down flywheel, deleted balance shaft and carbon fiber top cowl optimize weight. A competition engine calibration is optimized to take full advantage of 360 APX powerhead tuning. While bred for racing, this four-stroke powerhead is also designed to deliver unmatched durability and reduced maintenance in a competition environment.
A digital control offers smooth and precise throttle application. The 24-volt starter produces instant dockside starting in competition. Above-water exhaust offers unrestricted flow and produces an exciting tone for racing fans.
An overdrive spur gearset between the crankshaft and the gearcase increases the input shaft speed to the gearcase and produces the left-hand propeller rotation desired for Formula 1 circuit racing.
The 12-inch midsection is designed specifically for Formula 1 tunnel boat applications, with a structural wet sump driveshaft housing and integrated power trim and lift with remote pumps.
An evolved Mercury Racing Super Speed Master (IV SSM) outboard gearcase is direct-drive with no neutral or reverse shifting.
