1. There Are many Options In Electric Systems and Propulsion.  We will explore those systems that work well in sailboats both new and seasoned.  When considering propulsion and replacement of engines please consider the electric systems today they really work well.  There are systems that start turnkey for electric marine propulsion on sailboats from 22-55’ but you be the judge, research and ask questions.  This site and Jay Hafner is a resource for all propulsion, electrical, inversion, and battery needs.

Hybrid-Electric Drive

1. The EMotion system is true hybrid-electric drive. It can power the drive motors solely by electricity from the batteries - which can be charged from renewable energy sources - or from a DC diesel generator feeding through the battery pack.
   

2. EMotion Hybrids incorporate the latest in solid state electronics and permanent-magnet motor technology. One key to our system's efficiency is our motors' ability to turn larger, more efficient propellers than a comparable diesel engine can. A large prop turns more slowly and pushes more water in each revolution
