Falcon I is the MILD-HYBRID kit developed specifically to convert inboard endothermic engines with stern drive feet. The kit consists of a Thor inboard with respective accessories, an automatic clutch and an ECU that interfaces directly with the engine ECUs. The control of the system through a single throttle and a single display keeps operation simple and intuitive for the user. There are three navigation modes, hybrid/electric-only/combustion-only. While the electric motor is not running, the latter changes to generator and recharges the battery. The kits are developed directly with the engine manufacturers in order not to compromise their operation and warranty.
