Marine Electric Propulsion
Electric boating starts at Bellmarine. In the world of electric propulsion systems Bellmarine is the standard. The years of experience, quality, innovation and durability are a guarantee for pure boating pleasure!
Perfection in every detail.
All parts installed below decks have to be of the highest quality; moist and salt will take their toll and can have an effect on the durability of your drive system. Only the best materials are suitable and have been carefully selected.

New standard
With this complete new Liquid-cooled range of DriveMaster Ultimate and Performance, we are setting the standard in the electric boating market worldwide
Thrust
Standard, the motors are equipped with an integrated thrust bearing, allowing for very compact installation, less noise and higher overall efficiency in the drive train.Also, lining up the system and shaft is greatly simplified. You will notice the absence of vibrations.
Saltwater resistant
To keep you system in excellent condition, the motor housing is black anodised. The motor shaft, motor mounting bracket, flange adapter and the optional shaft adapter are manufactured from marine grade 316 stainless steel.
Liquid cooled
The motors are standard equipped with temperature regulated liquid cooling. Exact temperature management realises an efficiency improvement of up to 15%. The motors and controllers are equipped with a temperature sensor. All models can be supplied with external Fresh water cooling, Heat exchange or Intelligent closed loop cooling system, which is ideal for Seawater environments or use in zub-zero temperatures.
Protected
Where possible (IP68) waterproof connectors have been used to ensure reliability. All cable connectors are extra soldered and all contacts are gold plated.
Smart Controllers
The motor controller is the heart of our electric propulsion systems. The controller manages the motor power the cooling system and 
monitors the complete system, including the state of charge of your battery bank.The software is specifically designed by Bellmarine for electric propulsion and ensures efficient and trouble free sailing, a truly unforgettable experience.
The extra standard power boost mode allows for an extra 20% motor power during manoeuvring. A choice of 2 standard program settings guarantees you are always in full control of your craft. For rent a boat's, the combination of 2nd modus + boost is perfect; it ensures excellent manoeuvring without compromising efficiency! At the same time the controller monitors and starts/stops the cooling system automatically, depending on temperature and load.
All in One
A unique feature is the Plug-and-Play metal housing (EMC grade protection) of our motor controllers which are standard fitted with integrated
DC-DC converter.By means of a 13,8V DC AUX socket this converter can feed the complete on-board 12V network, including charging the batteries. Whether it’s the navigation lights, the fridge or listening to your favourite tunes on the sound system, you will have always plenty of power at your disposal.
3 Models (AC34-36-38/39)
Depending on the motor’s power rating, the systems are supplied complete with a matching controller, powerful enough to supply the required motor power at the highest efficiency. All models are water cooled and come with the same integrated user options. The nominal battery voltage is 48V for the standard systems, while for the more powerful systems the nominal voltage ranges from 96V up to 144V DC
