Using the sophisticated yet easy-to-operate user interface, you can monitor power consumption and charge levels. Fathom e-Power provides a convenient way to enjoy all the features of your boat for a longer, quieter and more eco-friendly day on the water.

 * Based on a fully charged system and typical power loads. Battery life will vary based on overall energy consumption.

The connected technology on the SLX 400 provides peace of mind by effortlessly conveying a boat’s location and status of vital systems to users through the Sea Ray+ mobile app. Boaters can remotely view geofencing, engine data and alerts. Boats on shorepower can also monitor battery and bilge data so you know your boat will be ready to go when you are.
