Yamaha's world-first hydrogen outboard unveiled on prototype boat

NewAtlas.com | C.C. Weiss | February 14, 2024

Yamaha previously announced it would show its prototype hydrogen-combustion outboard motor at the 2024 Miami International Boat Show, and it's gone the extra mile in bringing a prototype boat and fuel delivery system to go along with it. Yamaha calls its new hydrogen V8 outboard a world first for the recreational boating industry and has partnered up with Roush and Regulator Marine to install it into a working boat that will begin testing in a few months.

In developing its hydrogen outboard prototype, Yamaha adapted the technology it has used for land-based hydrogen combustion engines, including the one it installed on the Drive H2 golf cart concept revealed last month at the PGA Show. In this case, it created a hydrogen version of its flagship XTO outboard, an offshore V8 offering 425- and 450-hp ratings, the most powerful in Yamaha's outboard lineup. Yamaha has not released output specs for the hydrogen version, so we're not sure how close it comes to joining the gas XTO at the top of the Yamaha outboard family.

Building a combustion engine that can run on hydrogen is but one part of the equation; another major challenge is figuring out how to store and run the H2 to fuel it. For this aspect of the project, Yamaha turned to the experts at Roush for help.

The Roush name rings familiar to us primarily from its performance automotive division and Ford Mustang models and components, but the greater company includes engineering and clean tech arms that work in a wide variety of industries, from mobility and aerospace, to energy and defense. It has decades of experience working with hydrogen power systems across various sectors...more

Is H2 more dangerous than gasoline? You decide



Propane is dangerous yet there are thousands of Propane trucks driving around all of North America.
