Yanmar Tests Its First Hydrogen-Powered Boat

Yanmar just completed the first sea trial of its new hydrogen-powered boat, developed with Toyota, off the coast of Oita in Southern Japan. Yanmar says the 40-foot boat is the first to comply with Japan’s safety guidelines for hydrogen fuel-cell vessels. The boat used a marine hydrogen fuel-cell system that incorporates modules from Toyota’s Mirai car, the first mass-produced hydrogen fuel-cell car in the world; these cells have been used in large trucks and Tokyo’s buses for the past five years. The Yanmar boat, weighing 7.9 tons, was driven by a 250kW powertrain using two modules of polymer electrolyte fuel cells…

Torqeedo Making New 2-hp Electric Outboard

Torqeedo is now making a 2-hp electric motor designed to power dinks and tenders and some types of small sailboats and light fishing boats. The new Torqeedo, called the Travel 603, weighs only 34 pounds, including its 500Wh lithium-ion battery, and it costs just $1,999.99. The new outboard is the lightest in Torqeedo’s Travel line, but it has the standard outboard configuration with a tiller and throttle. “Our goal in introducing the Travel 603 is to make it easier for boaters to discover the unique benefits of clean, green propulsion for smaller craft,” said Dr. Ralf Plieninger, the company’s managing…

Merc Unveils Game-Changing 600-hp Outboard

Mercury just introduced its new V12, 600-hp giant outboard, a move that will surely cause more cruising boat owners to choose outboard performance. The world’s first V12, the new Mercury Verado also has the first steerable gearcase on an outboard; it pivots independently underwater while the engine remains fixed, providing more room for multi-engine applications and a wider steering angle for agile maneuvering. Mercury says the gear case rotates 45 degrees side to side, about 15 degrees more than a conventional outboard The 7.6 liter Verado also has the first two-speed automatic transmission on an outboard, optimizing engine rpm depending…

Italian Startup Creates Water Jet To Revolutionize Electric Boats

A groundbreaking Italian startup has developed a new water jet propulsion system that could revolutionize electric boats, giving them more speed and range than they have today. The outboard-mounted DeepSpeed hydro jet has already won several prizes for technology and innovation, and has patents from the European Union and Australia. It was developed by William Gobbo, an Italian banker and tech developer; Ernesto Benini, a professor of fluid dynamics at the University of Padua, and a team of 21 scientists, boat racers and hydrodynamic specialists under the umbrella company Sealence. DeepSpeed uses a holistic approach to powering an electric boat,…

Volvo To Stop Making Seven Marine Outboards

For the past several years, the outboard business has been on a tear. The demand for new outboards, even on traditional cruising boats, often outpaced supply. Yamaha couldn’t make its popular large outboards fast enough. Mercury upped its game and produced new outboards that became the power of choice even on such Down East boats at Hinckley and MJM. Suzuki stepped up its presence in the U.S. Three years ago, Volvo Penta, the Swedish giant, bought Seven Marine, a U.S. startup, and it started production of the entire Seven Marine lineup (527-hp, 577-hp, and 627-hp models)  last February in Tennessee.…

Cat Builds More Powerful 2025-hp High Performance Engine

If you’re looking for power, pure power, the new CAT C32B’s got it – in spades. Indeed, this latest high-performance marine diesel from Caterpillar has 2025-hp, or 5 percent more than previous C32 engines. But it looks the same and has the same connection points and footprint, making it attractive for both new builds and repowering options. New from the block up, the C32B is built to run at wide-open throttle up to 8 percent of the time. Cat says this is at least 3 percent longer than competing engines can run at that speed. The C32B also delivers more muscle…

Yamaha Tests Revolutionary New Electric Motor. See Video

Yamaha is starting sea trials on Aug. 7 on its revolutionary electric drive system that provides greater maneuverability, faster turning, and less vibration and noise than possible on most conventional drives. Yamaha says its new HARMO drive package is a “next generation control system platform” with an electric motor, a remote-control box, and a joystick. It generates about 10-hp and is available in single or twin applications. A major innovation is that the  prop is not driven through a central axle, as it is in conventional motors. Instead, HARMO has a Drive By Rim motor, where a ring of sequentially-activated…
