Outboard Motor Control Wiring Basics.

The end of the video has a bunch of useful diagrams to help understand the wiring.

This is the first video of my open source outboard control box for testing. The controller is currently setup to work with an Evinrude outboard and is designed to test all functions of the motor or add new features. The wire colors may be different for other brands but the functions will largely be the same.

1990's Evinrude 40HP used for testing.
