Overview

Combi Outboards was built on electric outboards and recently we have expanded our range with inboard motors. We offer a wide range of both air and liquid cooled electric motors of 5 up to 50 KW. This can be a motor to replace the existing one (conversion) or a complete set including propeller shaft installation. We develop all our systems in house and know what is important for the end customer. Our systems are practical in use, compact, plug and play and is easy to install.

Why Combi Inboard

Many sloops and cruisers were prepared for inboard combustion engines. Our customers are often looking to switch from a fuel drive to an electric drive and we can help them through all stages of the conversion. We also provide installations for new builds, including among other things, tour boats and work with marine architects and boat builders to realise the full benefits of electric power over conventional combustion engines.

  • Silent sailing

    Electric power in your boat is not only virtually silent and due to the lack of vibration of a combustion engine it is also wonderfully comfortable. When you sail with a Combi motor, this enjoyment will be tripled again.

  • Suitable for every boat

    Do you have an existing boat with propeller shaft installation? We can connect our systems with virtually any propeller shaft. For new construction we even supply the complete package with propeller shaft installation.

  • Compact and practical

    Our systems are constructed in such a way that all components are used in a motor housing. You just need to connect only the power cables. The engine foundation is prepared so that it is easy to install.

  • Cost saving

    Electric Power saves costs and is at the same time environmentally friendly. No high fuel costs, no high maintenance costs and a longer lifespan .

Unique features

What is distinctive about our inboard motors is that we have made the complete drive into a component. If you are building a yacht or a sloop then we can deliver the drive ready for installation, the system is also easily exchangeable. For existing situations we also offer complete solutions to make it easy for you.

Motor

Our Motors are available in both AC A-synchronic and BLDC PM motors. Both techniques have got there own benefits which suits your situation. All motors can be used as a direct drive for smooth and whisper quiet boating. We offer both options and can advise you on which type to choose.

Modulair Systems

Our inboards are designed in such a way that they can easily be connected to each other to achieve a greater capacity. Both motors can operate on the Master / Slave principle, but can also sail on a single motor. You can sail economically and quietly and at the same time you have the option for double power when required.
