Waterworld 4.0 i/h 10.0 i/h 20.0 i/h (hybrid) electric inboard motor 5 - 20 kW 48V

• Reliable. The proven Dutch technology and simple installation mean you can rely on WaterWorld propulsion. That provides peace of mind. 
  
  
• The motors have CESNI certification. This means they meet the stringent requirements for professional installation. For a pleasure craft, it is a sign of top quality; for a commercial vessel, it is a strict requirement.
  
  
• WaterWorld motors are brushless asynchronous electric motors, powered by a 48 Volt battery pack and directly driving the propeller shaft.
  
  
• Quiet and clean. WaterWorld motors operate silently. The quiet motor drives the shaft without transmissions. Enjoy the peace and quiet it provides and the clean air!
  
• Sustainable also means: Made in Holland. The WaterWorld systems are manufactured in our own country by the skilled professionals at Water World Electronics. Not in low-wage countries far away. And that means: no transport of products halfway across the world.
  
  
• Easy to install with adjustable engine mounts that fit most existing foundations.
  
  
• Motor and electronics in one, equipped with air cooling. Water cooling is unnecessary. Super efficient – Economical and longer cruising. The WaterWorld motor is so efficient that it produces little heat. Therefore, no water cooling is needed! This makes the installation simpler, there is no risk of blockages, and maintenance is minimal. Once on the water, another major advantage becomes apparent: you can cruise longer with your boat.
  
  
• Modern technology and design. When you lift the hatch, you see the sleekly designed motor and electronics. In daily use, the modern touch screen color monitor and the design of the throttles are particularly striking. In addition to the standard display included, it is also possible to view all information on your NMEA screen or on your iPad via the special WaterWorld app (iOS integration).
  
  • Information about the shift position of the control lever: forward, neutral, reverse
  • Current motor power in Watts
  • Revolutions per minute
  • Remaining cruising time
  • Notifications:
    • including too low or too high voltage
    • too high motor temperature, RPM lower than 70% of expected RPM and less than 500 RPM
    • measured speed is less than 85% of expected speed at maximum power
    • the measured RPM is equal to the expected RPM, but the current is less than 80% at maximum power.
      
• Suitable for intensive and professional use. WaterWorld systems are also used in charter vessels, tour boats, and workboats. The robust motors, which can also continuously deliver maximum power, make this possible. The same applies to the WaterWorld batteries, which can handle up to 3,000 cycles while retaining almost all their energy.
  
  
• A complete system with 3 year warranty: that gives peace of mind. The WaterWorld components are integrated into one system. Via a CAN data connection, the motor, controller, batteries, display, and throttle work seamlessly together. This way, you always have the necessary information on your display about the condition of the motor and batteries, and the remaining range.
  When purchasing a complete set, i.e., motor, Waterworld battery(ies), charger, and DC distribution set, in combination with mandatory commissioning and annual prescribed maintenance, you receive a 3-year warranty. 
  
  
• Sailboats can regenerate: meaning you can charge your battery while sailing. With Waterworld, you can regenerate steplessly. 
  In a full electric situation with a sailboat, depending on the speed from 10 kilometers per hour, you should expect 500 Watts to 2 kW; in a hybrid setup (rigid connection to the propeller shaft), you can get up to 8 kW. This option is available for the 10 kW and 20 Kw motor: WaterWorld Regeneration package for hybrid or regeneration for sailboats €695.
  
  
• Replace your diesel engine? A new diesel inboard engine is no longer an option, also because Waterworld is more affordable! 
  • 30 hp diesel: more than 100 kilograms, 80 dB (loud conversation), 25% efficiency, annual oil change, winterization, environmental pollution.
    vs 
    10 kW Waterworld: 76 kilograms, 45 dB (inaudible on the water), more than 85% efficiency, no maintenance, environmentally friendly.
    
    
  • Or consider an even more affordable pod motor.

Hybrid.
WaterWorld systems can also function perfectly in a hybrid setup. Both parallel-hybrid: with a diesel and WaterWorld both driving the propeller shaft. And also as a series-hybrid, where the internal combustion engine of a generator converts mechanical energy into electrical current, to be stored in batteries and to power the WaterWorld motor.

Two parallel versions: 4 kW Hybrid version 4.0i and 10 kW Hybrid version 10.0i.

• For parallel-hybrid, custom work is required, and we need the following information for a proposal:
  • Make and type of boat, waterline length, and displacement. 
  • Desired speed, cruising time, and range.
  • Is recharging by sailing on diesel desired?
  • Engine brand and type.
  • Maximum diesel engine RPM.
  • Speed at 1500 rpm with diesel.
  • Brand and type of gearbox (and gearbox reduction ratio).
  • Available space around the gearbox.
    Space above the gearbox or further aft around the propeller shaft is necessary. Space in front of the diesel engine is not usable.
  • Maximum applicable diameter for a sprocket pulley immediately after the gearbox. Common sizes are 135 or 155 mm.
  • How is the propeller shaft supported and (regarding force distribution) at what position? Photos of this are also welcome.
  • Space around the propeller shaft/gearbox flange regarding diameter. 
  • Gear ratio.
  • Angle of the setup.
  • Propeller shaft and bearing setup (support bearing, Python Drive present).
  • Water lubrication of the propeller shaft; water scoop / auxiliary pump during electric cruising?
  • Propeller type. This is for determining performance speed / torque.
  • What is known about the propeller and speeds at certain RPMs?
  • Ventilation inlet and outlet openings in the engine room.
  • Available space for batteries. 
    
    

• Hybrid WaterWorld Options:

1. A new Hybrid diesel engine complete with Waterworld 4.0i mounted: 
   27 hp Craftsman CM3.27 hybrid or 42 hp Craftsman CM4.42 hybrid. Including Twin Disc Technodrive TMC60-2R gearbox, Craftsman Alfa 20E panel with gauges and flexible engine mounts. Prices are listed on this page.
   

• Hybrid installation time, therefore, depends entirely on factors such as motor mounting, 4 - 6 days.
• Excluding WaterWorld Service Work: - installation guidance in the preliminary phase - commissioning on location - actual hours and travel expenses based on post-calculation, estimated 700,- for 1 day including VAT. In principle, the customer can purchase commissioning directly from WaterWorld, preferably a business customer. It is important that the installer is present during commissioning. Sometimes it is necessary for them to make some fine-tuning/adjustments/alignment at that moment.
  WaterWorld checks the installation and then regulates the regeneration (lower and upper values), checks safety features and limit switches on Morse control + test runs, checks under load, heat development in the motor, controller and wiring, etc.
  Additional costs for Hybrid integration with current motorization; based on: Can Open; delivery of safety kits (e.g., sensor on current throttle/gearbox); adjustment/test run of control on existing setup (e.g., torque/nominal load) 2,195,-
