The QuietTorque™ 20.0 provides 48Vdc electric propulsion with high sustained output and is ideal for cruisers and day sailors alike.Typically, the QuietTorque 20.0 would replace a 25 to 40hp diesel engine. By using dual PMAC (Permanent Magnet AC) motors, Electric Yacht can produce this powerful, compact, Plug-n-Play, light weight, air cooled system and stay within the safe low voltage standard.  Typical battery size is 400Ah at 48Vdc.  These systems can be installed by a competent boat owner using simple tools and the easy to mount Electric Yacht system.  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.
