2024 Mercury Racing 400R

2024 Mercury Marine® Verado V10 400R Potent Performance

The Mercury Racing team has created a worthy successor to the legendary L6 400R outboard. The V10 400R offers more low-end torque, more peak horsepower, and better fuel economy than the L6. The Mercury Racing 400R features a new naturally aspirated V10 5.7-liter powerhead that is based on the proven design architecture of the V8 4.6-liter Mercury Racing 300R model. The 64-degree powerhead displaces the 5.7 liters with a 6000-6600 WOT RPM range enhances peak horsepower

Setting a new standard in performance, the race-proven Sport Master gearcase is a surface-piercing design intended for boats capable of exceeding 85 mph and features low water pick-ups and a crescent leading edge to maximize speed and efficiency.
