Installation
The process of installing a KRONOS electric motor
Designed for quick and easy assembly, the KRONOS motor is “plug and play”, only 3 key components need to be installed. In addition, as it will have been sized and tested on a test bench, the installation will take place in the best conditions.
Preparing the boat
If it is a retrofit, we will remove all the components of your old engine, in order to obtain the necessary space for your new KRONOS engine
Installing the internal elements
We will then install the energy management system and the battery bank, divided according to the specifications, and the regulations in force, in order to respect the center of gravity and the waterline.
Installing the motor
We will also install the motor on the boat's transom, then connect it to the inside of the boat in “plug and play” mode.
Checks, tests & training
Finally, we will carry out some tests to validate the proper functioning of the system in real conditions. We can take the opportunity to also train you on how to use the system.

A technical question, missing information, or a simple curiosity?
What is the performance of electric motors compared to thermal engines?
The performances of electric motors are often superior to those of combustion engines in terms of instantaneous acceleration and torque from the start, thanks to their ability to provide maximum torque from the start.
How do you protect an electric motor against salt water?
The motor is IP67 certified, which means it is waterproof to submersion up to 20 meters deep for 30 minutes. In addition, it is coated with epoxy paint that is resistant to corrosion and salt water, ensuring effective protection in marine environments.
How reliable are marine electric motors?
Marine electric motors are very reliable due to their simple design, with fewer moving parts compared to internal combustion engines. They require less maintenance, which reduces the risk of breakdowns and ensures consistent performance over a longer period of time.
What is the energy consumption of an electric motor?
Our electric motors range from 50 kW to 400 kW. At low speeds, consumption can drop to 10 kW, which ensures a minimum autonomy of 10 hours on any boat, depending on specific sailing conditions and battery capacity.
What maintenance is required for an electric boat motor?
The maintenance of an electric boat motor includes a complete overhaul every 20,000 hours of navigation. It can be carried out in your shipyard (subject to partnership), without the need to be put out of the water. It is recommended that you check the water/water exchanger visually every year to ensure that it is not obstructed.
