COX 300-350hp
Designed with sustainable innovation in mind, the V8 diesel outboard is a fuel-efficient, eco-friendly engine built for maximum speed.

Twin Turbo
The V8 features twin turbochargers that produce significantly more torque at lower RPMs and maintain power across the entire engine speed range.

Vertical Crankshaft
The vertical design allows for efficient packaging and direct drive to the gearcase, ensuring tighter transom centers for multi-engine installations.

Power Trim and Tilt
The V8 PTT (Power Trim and Tilt) bracket is built to withstand the harshest conditions and has undergone rigorous endurance testing.

Gearcase
The gearcase has been specifically designed to withstand high torque, even in the most demanding marine conditions.
