DIY Enthusiast Creates High-Powered Electric Jet Boat Using Tesla Components

In an era where electric propulsion is slowly gaining traction in the marine sector, a dedicated team of DIY enthusiasts has taken innovation into their own hands. A prominent YouTube channel, known for its creative engineering feats, has unveiled a remarkable custom-built electric mini jet boat, demonstrating the potent possibilities of repurposing electric vehicle technology for unique watercraft. This ambitious three-year project underscores a growing trend of individuals pushing the boundaries of electric mobility beyond conventional land-based applications.
The journey began with the realization that commercially available options for a compact, high-performance electric jet boat were virtually non-existent. Undeterred by this market gap, the creators behind the "Prop Department" YouTube channel embarked on designing and constructing their dream vessel from scratch. Their initial design incorporated a Tesla Model 3 motor, delivering a respectable 280 horsepower. However, their quest for higher performance led them to upgrade the powertrain significantly.
The team eventually transitioned to a meticulously customized Tesla Model S motor, which was fine-tuned to produce an impressive output exceeding 350 horsepower. This upgrade necessitated several critical modifications, including replacing two of the original battery modules due to faulty cells that limited power delivery under heavy load. An aftermarket Battery Management System (BMS) was integrated to oversee the reconfigured battery pack, with each custom module featuring liquid cooling, mirroring the sophisticated thermal management present in original Tesla units.
To further enhance the boat's performance, a custom stub shaft was directly fitted to the motor's output, bypassing the need for a traditional transmission and significantly increasing the final RPMs delivered to the pump-jet. The entire system is managed by an aftermarket controller board for the motor inverter, providing the builders with unparalleled control over the drive unit and circumventing the standard safety limitations imposed by Tesla's stock systems. While the boat currently utilizes a J1772 charge port, precluding fast charging capabilities, the project stands as a testament to the team's engineering prowess and dedication. The creators acknowledge that minor refinements are still in progress, but the vessel is already hailed as an exhilarating ride, possessing ample power for its compact size.
This handcrafted electric jet boat represents a significant achievement in personal vehicle modification and sustainable engineering. By ingeniously integrating advanced electric vehicle components, the creators have not only fulfilled their vision for a high-speed electric watercraft but also provided valuable insights into the potential of electric powertrains in novel applications. Their work demonstrates how passion and technical skill can overcome the limitations of existing commercial offerings, paving the way for future innovations in electric boating.
