Reliable diesel outboards for fishing and aquaculture
Fuel-efficient, high-torque propulsion for daily operations at sea
Built for tough, daily use
Across key US fishing regions – from the icy waters of Alaska to Maine’s famous lobster fishing and the South’s offshore fishing spots – fishing and aquaculture play a vital role in the economy and local livelihoods. Cox Marine diesel outboards deliver the power, efficiency, and endurance required for professional operations at sea.
Fishing and aquaculture vessels often operate in remote or open-water environments for long hours – conditions where reliability is critical. Cox Marine’s V8 diesel outboard provides high torque at low RPM, allowing crews to work efficiently even under heavy loads or in choppy seas.
With growing demand in US markets, Cox Marine engines are becoming a trusted solution for operators seeking a cleaner, longer-lasting alternative to gasoline outboards.
Why fishing and aquaculture operators choose Cox Marine
Longer range, fewer refuels
With great fuel efficiency than gasoline engines, vessels can travel further and operate longer – ideal for long fishing runs or tending to multiple aquaculture sites in one trip.
High torque for heavy loads
Whether hauling gear, nets, or farm equipment, Cox Marine outboards deliver smooth, powerful propulsion that gets the job done with control and confidence.
Engineered for dependability
With extended service intervals and a rugged marine build, the V8 is designed to withstand the rigors of daily commercial use in challenging sea environments.
