The QuietTorque™ 15.0 LC provides 48Vdc electric propulsion with high sustained output and is ideal for hybrid applications.  Typically, the QuietTorque 15.0 LC will replace a 18 to 30hp diesel engine. By using a liquid cooled PMAC (Permanent Magnet AC) motor, Electric Yacht can produce this powerful, compact, Plug-n-Play system and stay within the safe low voltage standard.  Typical battery size is 300 to 400Ah at 48Vdc.  These systems can be installed by a competent boat owner using simple tools.  To be prudent, we recommend that a certified marine electric technician review the completed system.  Each system is engineered for your boat to maximize the speed and range of the boat.  The System is backed by Electric Yacht’s three-year limited warranty.
