Custom Rotomolded Underwater Scooter & Electric Bodyboard Hull with Dual Thruster Channels & Aluminum Tooling Mold for Water Sports OEM/ODM

Engineered for high-speed marine propulsion and personal watercraft applications, our Custom Rotomolded Underwater Scooter & Electric Bodyboard Hull provides an ultra-durable, buoyant, and hydrodynamic housing solution for dual-jet water scooters, sea scooters, and motorized swimming kickboards.

Manufactured from high-density, impact-resistant LLDPE/HDPE resin via advanced rotational molding, this seamless U-shaped hull is designed to withstand severe hydrostatic pressure, saltwater corrosion, and high-impact wave collisions. The enclosure incorporates twin propulsion jet channels, ergonomic handgrips, a sealed central battery compartment, and molded-in brass inserts for waterproof electronic control panels.

Accompanied by our custom 5-axis CNC-machined cast aluminum mold tooling, we guarantee high dimensional accuracy, uniform wall thickness across complex curved channels, and flawless surface finish. We deliver end-to-end OEM/ODM custom development from 3D hydrodynamic CAD modeling to complete mold fabrication and plastic part mass production.

• Hydrodynamic Dual-Jet Architecture: Seamless U-shaped body optimizes water intake and thrust delivery while offering maximum stability for riders.
• High Buoyancy & Impact Endurance: One-piece rotomolded construction ensures zero risk of delamination, exceptional buoyancy, and superior puncture resistance.
• Integrated Ergonomic & Mounting Features: Features molded-in dual handles, a waterproof battery/ESC hatch, and brass inserts for easy electronics assembly.
• Precision Aluminum Tooling Mold: Heavy-duty cast/CNC aluminum mold ensures rapid heating, balanced cooling, and flash-free parting lines.
• Full Turnkey OEM/ODM Engineering: Complete custom manufacturing from 3D CAD design, fluid dynamics simulation, custom color matching, to mass production.
