Rumery's is proud to have partnered with E-TECH, electric motors for yachts and boats.
Using state-of-the-art technology, E-TECH has worked to develop classic outboards, saildrives, and technics that are efficient and durable.
E-TECH produces electric outboards with the classic look of an outboard. With theses outboard engines we respond to the demands of the client not wishing to change much on the appearance of their boats, but requires the benefit of strong and efficient electric propulsion.
Our Saildrives allow clients is to adopt the sail drive for an electric motor. This is what we have done successfully with the E-TECH engines
Electric drives from E-TECH are constructed around the BLDC motor. A permanent magnet, brushless synchronous motor is the most efficient electric drive. Economical, very low maintenance, silent and compact, all in a seawater resistant and watertight aluminum casing.
Every E-TECH WG (inboard) system has a shaft clamp to connect with the existing propeller shaft and can be delivered in the required size and diameter. The engine supports can also be adapted to any size engine.
E-TECH drives with closed circuit water cooling is supplied with Push-In connections on the cooling hoses. All electric connections are color coded. The cooling circuit is a closed circuit, which can be filled with common cooling fluid. Customers can choose between a heat exchanger under the boat or a radiator cooler that can be mounted in a well ventilated spot of choice.
All E-TECH motors have a double acting build in thrust bearing. The axial thrust from the propeller is guided efficiently and without resistance to the engine casing.
E-TECH electic drives (4kW and higher) are strong generators, allowing the motor to charge batteries. Shaft endings on both sides of the engine makes it easy to build an in-line hybrid configuration.
Using a Bluetooth connection with an android system, any user can easily connect with the controller, allowing to reprogram the controller (for engine speed limitations, for example).
Every E-TECH drive system is a complete system. The set contains everything to install a ready to go elective drive system in your boat!
