Yamaha Unveils Hydrogen-Powered Outboard With Prototype Fuel System

Yamaha Motor unveiled the world’s first hydrogen-powered outboard for recreational boats along with a prototype fuel system integrated into a vessel that the company plans to further refine for testing later this year. (Earlier post.) The effort is part of Yamaha’s strategy to achieve carbon neutrality by deploying multiple technology solutions.

Yamaha joined forces with Roush to develop the fuel system to power the new outboard and collaborated with long-time boat builder partner Regulator Marine to build a boat suitable for testing the prototype outboard. Together, the companies plan to begin testing the protype for viability on the water in the summer of 2024.

By working with Roush on the fuel system engineering, Yamaha gains the benefit of more than two decades of hydrogen systems integration and research.

When you look at Roush’s history with hydrogen, it ranges from land speed record vehicles to spacecraft. A lot of that knowledge we’ve acquired over the years we are now applying directly to this Yamaha project. We are the fuel systems integrator, responsible for fuel systems designs, all of the specifications development, physical integration, safety system analysis as well as testing and development. Yamaha is trying to determine if hydrogen can successfully be used in this market, and I think we will find out the answer is ‘yes.’

—Matt Van Benschoten, Vice President, Advance Engineering, Roush

Regulator Marine built a hull based on the 26XO and modified it to accommodate the hydrogen tanks necessary to power the new outboard. Together, Yamaha, Regulator and Roush displayed the boat hull, fuel system and outboard to demonstrate how hydrogen could work as a possible fuel source in a marine environment. Also, the effort allows engineers to begin the process of determining marine standards for the use of hydrogen in vessels.

If we don’t look for a new source, we won’t find a new source. Innovation starts by asking questions. It creates a little angst, but at the end of the day good stuff comes out of innovation. In the future, as we design boats, if this proves what we think it will, it could be very possible that we are designing hulls around these hydrogen fuel tanks.

—Joan Maxwell, President, Regulator Marine

Yamaha announced the hydrogen outboard project last December. Further demonstrating the company’s commitment to a multi-technology approach to carbon neutrality, Yamaha recently announced plans to acquire all shares of electric outboard company Torqeedo. (Earlier post.) In addition, Yamaha continues to promote the use of sustainable fuels within internal combustion outboard engines as another alternative.
