COMBI Electric Propulsion Systems

Founded in 1979 in the picturesque waterside town of Giethoorn (known to some as the Venice of the Netherlands) with a mission to supply hire vessels with environmentally friendly propulsion. 4 decades later hundreds of Combi electric motors power boats, carrying thousands of tourists and locals navigating the beautiful waterways of the town daily. In recent years Combi expanded into a larger modern production facility just a few kilometres away from Giethoorn in Vollenhove (The Netherlands).
Combi’s dedication to high quality and specially developed marine electric drive systems has helped them to reach the position of one of the leading international suppliers of high-performance propulsion solutions for the maritime market. They are an innovative company specializing in the development of green power systems for all types of vessels. Combi started out producing electric outboards, gaining experience in the field they steadily expanded the range to include inboard motors. A wide range of both air and liquid cooled electric motors of 5KW-50KW are available. All are developed in house, Combi know what is important for the customer. Their systems are easy to install, plug and play, practical in use and compact.
A Combi system in your boat is not only virtually silent there is also very litle vibration and therefore is wonderfully comfortable when sailing with a Combi motor.
