Automatic engine kill switch Mob+

The Fell Marine MOB+ is a wireless kill switch designed to replace the traditional tether on your boat. It provides unrestricted movement while automatically cutting the engine if you fall overboard.

The system uses a base unit (xHUB) mounted on the console and a portable transmitter (xFOB). If the xFOB wearer moves more than 15 meters away or falls into the water, the connection is lost and the engine stops in a fraction of a second.

The secure range between the xFOB transmitter and the xHUB unit is approximately 15 meters. Beyond this distance, the system considers there to be a hazard and triggers an immediate engine shutdown.

The MOB+ system allows connecting up to 4 xFOB transmitters simultaneously. This enables protecting one helmsman and up to three passengers at the same time for optimal crew safety.

The proprietary WiMEA protocol is specifically designed for safety at sea. Unlike standard Bluetooth, it ensures an ultra-fast, robust connection without interference, guaranteeing instant triggering in case of emergency.

Yes, the xFOB transmitter is IP68 certified. It is fully watertight and designed to withstand prolonged immersion, which is essential for a marine safety device.

The xFOB transmitter offers approximately 300 hours of battery life. It uses a standard battery that can be easily replaced by the user.

As soon as the autopilot wearing the xFOB falls overboard, communication with the xHUB is instantly cut off by immersion. The system then triggers automatic engine shutdown in a fraction of a second.

Yes, the system is designed with a manual bypass mode. After an emergency stop, passengers remaining on board can restart the engine after a few seconds to retrieve the person who fell overboard.

The Fell Marine MOB+ system is designed to replace your traditional mechanical kill cord. You no longer need to physically attach yourself to the console.

The xHUB base unit is highly versatile and connects directly to your boat's electrical system, whether it is 12V or 24V.

Installation is straightforward. The xHUB unit is designed to fit into a standard 51 mm hole, which is a very common size for marine navigation instruments.

The MOB+ interfaces with your boat's electrical loom. It is typically wired in parallel or in series with the wires of your existing kill cord, depending on the make and model of your engine.

Yes, the system is fully compatible with most outboard engines on the market, including leading brands such as Yamaha, Mercury, Suzuki, Honda, and Evinrude.

Yes. The Fell Marine MOB+ is compatible with both outboard and inboard engines, provided it is interfaced correctly with the engine kill circuit.

Yes, the xHUB unit has a manual mode. You can activate the system directly from the console to start and use the boat even if you don’t have your transmitter with you, although this disables wireless security.

The xFOB transmitter is very compact and can be worn in several ways depending on your preferences:

Around the wrist with a dedicated strapAround the neck with a neck lanyardAttached to your lifejacket or belt

No, as long as you remain within the safe range of approximately 15 meters and the transmitter is not submerged, you can move freely on deck without risking an engine cut.

The system uses the proprietary WiMEA protocol, specifically designed to avoid interference with other onboard equipment (VHF, chartplotters, phones), ensuring total reliability.

No, the Fell Marine MOB+ system is fully autonomous. It requires no smartphone app or internet connection to operate and ensure your safety at sea.
