The problem
Traditional engines chain your trip to the size of the tank. Fully electric boats chain it to the nearest outlet.
Noise, vibration, and a generator droning at the dock — the exact discomforts a well-engineered hybrid simply removes.
Pure combustion pollutes more than it has to. A fully electric transition on the water is still years from being real for most owners.
Why HYBDOR
Up to 90% more efficient across four fronts at once — range, comfort, emissions, and sustainability.
Combustion and electric in one powertrain: more range, with no dependence on a fuel dock or an outlet — go farther on the same tank.
Less vibration and zero noise in electric mode. Climate control and house loads with no generator — true silence at the dock.
Lower emissions in combustion mode and zero in dedicated electric mode — less impact on every trip out.
A powertrain with global automotive DNA (Renault–Nissan–Mitsubishi Alliance): built to last and to evolve, not to be thrown away.

The engine lineup
Three engines, one standard: high performance with up to 90% more efficiency. Pioneer batch, limited availability.
Now reserving — pioneer batchFlex-fuel outboard — ethanol or gasoline
A high-output flex-fuel outboard engineered for whatever's in the tank — ethanol or gasoline. Lighter, more efficient, and built to outlast the competition.
Now reserving — pioneer batchFlex-hybrid — combustion + electric
The flagship of the lineup: combustion power paired with electric range in a single powertrain. Automatic, silent handoff between both modes.
Now reserving — pioneer batchOnboard comfort — all-electric hospitality
Climate control and house loads powered entirely by the battery bank. No generator, no noise at the dock.

The global engineering
The DNA, scale, and reliability of global automotive engineering (Renault–Nissan–Mitsubishi Alliance), brought underwater. Exclusive technology with serious industrial backing.
The strategic governance
Technology-ecosystem intelligence and rigorous corporate governance, turning innovation into a secure, scalable asset.
Frequently asked questions
HYBDOR builds high-performance marine electrification systems. Its flex-hybrid engines combine ethanol, gasoline, and electric power in a single powertrain, for boats 25 to 40 feet — with no dependence on charging infrastructure.
Up to 90% more efficient than an equivalent traditional engine, across four fronts at once: range, comfort, emissions, and sustainability. In a real-world test spanning 75 miles along Brazil's southern coast, the system delivered 82% in fuel savings versus a comparable conventional boat.
Three: the H170-Flex (a 168 hp flex-fuel outboard for ethanol or gasoline), the DUOTECH 200E (the flagship flex-hybrid, 168 hp combustion plus 25 hp electric with automatic mode switching), and HYBDOR Marine Climate (battery-powered climate control and house loads, with no generator and no noise at the dock).
No. The install is modular and plug-in, engineered for boats 25 to 40 feet with no major structural rework — it's built to fit the boat you already own.
Commercial operators (water taxis, charter fleets, and institutions running over 1,000 hours a year, with an estimated 6-month payback) and boat owners using their vessel for leisure (an estimated 18-month payback), who gain silence, range, and zero emissions in electric mode.
The powertrain carries global automotive DNA, built with HORSE Powertrain Solutions (Renault–Nissan–Mitsubishi Alliance engineering) and TechSolution for governance and dynamometer validation. It's been tested on the water since 2022, with proof of concept validated in real operation.
