Thinking about a new 20hp 15” with electric start and tilt. Warranty at 5 years is a plus as well. I was between the Tohatsu and the Yamaha 25 but I’m leaning towards the Tohatsu. Will an Odyssey 680 be enough to run the motor and run tabs, gps, and nav lights? How do I hook up the motor to charge the battery? Seems like a good motor with regards to weight/power/price and power tilt is a huge plus.
