The Cox V8 delivers up to 1,052 Nm of torque at just 2,600 RPM, providing powerful acceleration and precise control under heavy loads. Whether for tactical response, patrol, or commercial duty cycles, this low-RPM torque ensures vessels plane quickly and operate efficiently.
-
With fuel consumption as low as 260 g/kWh, Cox diesel outboards deliver up to 30% greater efficiency than comparable gasoline engines. This translates into longer missions, fewer refueling stops, and reduced logistical costs for both government and recreational operators.
-
Diesel’s higher flashpoint and spark-free ignition dramatically lower fire and explosion risks compared to gasoline. This makes Cox outboards the preferred choice for military, defense, and first responder operations where safety is mission-critical.
-
Cox diesel outboards meet or exceed EPA Tier 3, IMO II, RCD II, and BSO-II standards. These certifications ensure environmentally responsible operation while supporting procurement requirements for international defense and government fleets.
-
Tested in punishing offshore conditions, the Cox V8 is purpose-built for reliability with a commercial warranty of up to 1,500 hours. Its robust architecture and extended service intervals mean more time on mission and less downtime in the shop.
