About us.

Jeff “Mojo” Jess is a man driven by speed and a deep passion for building. For him, the thrill isn’t just in the destination, but in the journey of creating something incredible from the ground up. This passion is the force behind Mojo H2O, a company dedicated to building custom mini jet boats that are both a work of art and a testament to high performance.

When he’s not in the shop, Jeff pursues a couple of high-octane hobbies. He’s an experienced jet pilot with a keen understanding of aerodynamics, power, and precision. He also knows a thing or two about off-road thrills, having spent countless hours driving his high performance UTV. He also spent years building and driving stock cars and sand cars, a background that gives him a unique perspective on engineering for speed and durability. These experiences, combining the worlds of air, asphalt, and dirt, have given him a unique perspective that he applies to his marine creations.

That’s why his boats aren’t just fast; they’re engineered for performance. His designs have pushed the limits of what’s possible, culminating in the creation of the world’s fastest mini jet boat, the Piranha. This record-breaking vessel is the crown jewel of MojoH2O, his team of builders and fabricators who share his relentless drive to innovate and dominate.

For Jeff, every boat is more than just a project—it’s a reflection of his dedication and craftsmanship. Whether he’s navigating a jet through the sky or pushing the Piranha to its limits, his mission is simple: build it better, faster, and more powerfully than anyone else.
