Ring Power / Cox Marine Diesel Outboards

What Ring Power / Cox Marine Diesel Outboards does

Ring Power, through its Cox Marine Diesel Outboards division, is the U.S. distributor of Cox Marine's V8 diesel outboard engines, headquartered in Saint Augustine, Florida. The company sells a single product platform — the Cox V8 in 300 hp and 350 hp configurations — to three customer segments: government and defense (patrol, tactical response, first responders), commercial maritime operators (fishing, transport, search and rescue), and recreational boaters. The propulsion technology is purpose-built diesel, differentiating on high torque output (up to 1,052 Nm at 2,600 RPM), fuel efficiency (as low as 260 g/kWh, cited as up to 30% better than comparable gasoline engines), safety (diesel's higher flashpoint and spark-free ignition), and a commercial warranty up to 1,500 hours. The product carries EPA Tier 3, IMO II, RCD II, and BSO-II certifications, enabling procurement by U.S. and international defense and government fleets.

The business model is primarily hardware sales through a U.S. dealer network, supplemented by direct government procurement and parts and service revenue. Cox diesel outboards are installed as OEM equipment by six boat builders — Albemarle Boats, Freeman Boatworks, Front Runner Boats, Intrepid Powerboats, Phenom Yachts, and Hammer Yachts — embedding the product into specific hull designs. Pricing is not publicly disclosed and is quote-based, with multi-year contract cadences for commercial and government sales. Marketing runs across LinkedIn, Facebook, and Instagram at the top of funnel, with dealer support and technical specification request flows at mid- and bottom-of-funnel.

Ring Power has expanded into defense programs as a partner in the STEAMRACER autonomous surface vessel consortium (announced 2026-02) for the U.S. Navy's MASC program, supplying diesel outboards alongside shipbuilders (St. Johns Ship Building, TOTE Services), design firms (Incat Crowther), industrial partners (EMI-W&O), autonomy providers (Sea Machines Robotics), and secure communications vendors (Sierra Nevada Corporation). The company is privately held, with no disclosed funding rounds, M&A activity, headcount data, or revenue figures in the source material.

Expansion highlights5 records

Direct peers

• Cox Marine: The actual manufacturer of the Cox V8 diesel outboard engine that Ring Power distributes in the U.S. As the upstream product company, it is the most directly comparable peer — same product, same technology, different role in the value chain.
• Steyr Motors: Austrian manufacturer specializing in high-performance diesel marine engines for military, commercial, and pleasure craft. Most directly comparable niche diesel marine propulsion peer to Cox Marine.
• Seven Marine: Manufacturer of high-horsepower outboard engines (originally 557 hp, now broader range) targeting premium recreational and commercial boats. Comparable as a high-power outboard specialist pursuing similar OEM partnerships with premium boat builders.

Broad incumbents

• Volvo Penta: Global marine propulsion and power systems provider (part of Volvo Group) offering diesel and electric marine engines plus complete drivelines. Comparable as a diesel marine propulsion incumbent targeting commercial and government marine customers.
• Suzuki Marine: Global outboard manufacturer with a wide horsepower range and strong dealer footprint. Comparable as a competing outboard brand for the same boat builders, commercial operators, and government buyers.
• Honda Marine: Outboard division of Honda offering mid-horsepower gasoline outboards. Comparable because it competes for recreational and light-commercial outboard buyers in the same horsepower bands adjacent to Cox's 300/350 hp.
• Caterpillar Marine: Major marine diesel engine manufacturer (Cat and MaK brands) for commercial, defense, and offshore vessels. Comparable as a diesel marine propulsion incumbent serving government/defense and commercial operators — and notably, Ring Power is a long-standing Cat dealer.
• Yamaha Marine: Global outboard engine leader offering a broad horsepower range of gasoline outboards. Comparable because it competes for the same customer (boat owners, commercial operators, government fleets) but with a gasoline-dominant portfolio rather than a diesel specialty.
• Mercury Marine: Major U.S.-based outboard and sterndrive manufacturer ( Brunswick subsidiary) with extensive dealer network. Directly comparable as an outboard propulsion provider targeting commercial, government, and recreational segments.

Emerging players

• Torqeedo: Electric marine propulsion specialist (owned by Deutz AG) producing electric outboards and inboards. Comparable as an emerging alternative propulsion player addressing the same recreational and commercial marine customers with a different technology approach.
