Cox Marine Diesel Outboards
Powerful, efficient propulsion built for New Zealand waters
Designed with one mission in mind — deliver maximum performance with minimal fuss. The Cox Marine V8 diesel outboard range arrives in New Zealand via our authorised distributor to serve everything from commercial workboats to recreational fishing vessels. With industry-leading torque, outstanding fuel efficiency and future-proof emissions credentials, Cox delivers a superior outboard solution for Kiwi operators.
High torque at low RPM
Whether you’re powering a charter vessel off the west coast, a work-boat navigating Fiordland or a family runabout in the Hauraki Gulf, Cox’s V8 diesel outboards provide exceptional low-rpm torque for smoother, more controlled acceleration and better hull control. In fact, the V8 delivers up to 1,052 Nm of torque — letting your boat move confidently through the water with fewer revs, less strain and improved durability.
Exceptional fuel savings & lower lifetime cost
Fuel is one of the largest operating costs for marine operators in NZ. The Cox V8 diesel outboard offers up to 30 % better fuel efficiency compared with a comparable 300 hp petrol outboard — translating into fewer fuel stops, longer range and lower cost per hour on the water. With a construction designed for longevity, expect an outboard with a service life up to three times that of a typical petrol model.
Clean-burning, future-friendly engine
Cox is committed to sustainable marine propulsion. The V8 diesel outboards carry major international certifications—including EPA Tier 3, IMO II, RCD II and BSO-II—demonstrating compliance with strict emissions standards and ensuring the engine is ready for regulated waters and future-legislation. On top of that, Cox has already tested compatibility with renewable diesel (HVO) and is working toward zero-emission hybrid solutions. For New Zealand operators looking to reduce carbon footprint and operating cost, that’s a win.
Ideal for a wide range of applications
The Cox V8 diesel outboard offers versatility across sectors — whether you’re working or playing:
Fishing & charter boats: Longer range and more time on the water thanks to fuel savings.
Commercial workboats & pilot vessels: Built for durability and designed with global support networks to reduce downtime.
Rescue, coastguard & emergency service craft: Instant torque, high reliability and lighter fuel load make it a strong choice in critical applications.
Passenger & sightseeing vessels: Lower fuel usage, extended service life and cleaner emissions keep your operation efficient and compliant.
