Mob+ Wireless Man Overboard System

I've had this product for over a year on and I love it. It was simple to install and once on, it allows me to move around my boat without worrying about attaching a string every time. This worked so well, I decided to purchase three more wristbands with chips for the rest of my family or fishing buddies. This gives me peace of mind while boating. FYI, I tested it by placing my arm in my bait tank and the engine shut off right away. I then parked my boat with the engine running and jumped into the water and the engine shut off. I highly recommend this product for any boat owner or jet skier. FYI, just remember to replace your wristband chip batteries every season, just to be safe.

4 year update: Zero problems. Buy this thing, you won't regret it!As a lifelong boater I've seen many people unexpectedly ejected from their boats, including myself. It usually turns out okay but when it doesn't people die. If you've ever forgotten to wear the wrist strap you need this device.I am very impressed with the functionality and think devices like this should come standard in every new boat of any size.One of the little features I like is that after first turning on the ignition I have to press the button on the fob to start the boat. This reminds me to ensure the fob is attached to my body before getting underway. I keep my fob in a little draw-string pouch attached to a carabiner clip and just clip it to my person. I think the wristband is overkill.The only real issue I have is the "boot up" time. It takes a few seconds to power on after you've turned on the boat's ignition before you can press the button on the fob and get underway. I feel this could be a safety issue if I have to get underway in a hurry - like when some drunken pleasureboater is about to hit me. I therefore tend to leave the ignition on while drifting and use the kill switch to stop the motor instead of turning it off with the key.If you have an outboard the install can be difficult. I had to disassemble the control lever box for my motor, as it contains the ignition, kill switch, and other associated wiring. Tapping this wiring inside the limited space of the control box and running it to my dash was not an easy task. I ended up having to use scotchlok-style wire taps which is far from an ideal solution in a marine environment. I put grease on everything to hopefully prevent corrosion. I think the device would be very easy to install if your kill switch and ignition are installed in a dashboard.

This MOB+ is a product whose time has come. Although kill switches have been installed on new boats for the past 25 years their usage is very low due to the need to tether yourself to the helm with a lanyard. Most people try this out for a while and finally give up on it because it's such a pain.I installed mine in under an hour. Got out my VOM and started testing the functionality when I pressed the xFOB. It reliably cut the ignition circuit whenever the xFOB was out of range or in some water. Thumbs up for functionality.The one small issue I had is that I have an I/O. The ignition circuit has both the electric choke heater as well as the ignition coil in it. The choke heater draws 3.5A. The ignition coil draws 1.2A / 1,000 RPM. This means that you have to allow for the ignition circuit to draw 10A. Since the ignition circuit length is double the length of the distance from the engine to the helm/console you have to take that into account when determining the wire gauge that will support 10A of current draw. In my boat that distance is 10 feet which means the circuit is 20 feet in length. Looking at a marine ampacity chart shows I need 10-12 gauge wire gauge to support 10A of current draw over that length. Where the issue comes in is that the xHUB splices itself into the ignition circuit and therefore would need to have that same gauge wiring in order to not present a fire hazard. What I found was the xHUB wires were only 18-20 gauge for the ignition circuit. This is far too small to support 10A of current draw over the total ignition wiring length. How I solved this problem was by purchasing an Ignition Power Relay that is "ignition protected" and wiring that into the ignition circuit. It requires very low current to pull the relay in and can support up to 30A of current draw on the outputs. I think Fell Marine should put a notice/warning to this effect in their instructions for those of us with I/O's and standard points ignitions and electric chokes who are installing this MOB+ system.

Due to frequent nighttime boating I need to protect my night-vision….and the MOB base unit has bright LEDs and Flashing Green circles which continue for over 3 minutes after engine start. Therefore, I mounted the base unit down low/out-of-direct-view ….which required splicing 4 new leads to the original 8-inches of wiring harness. The unit Also needs circuit-protection…. I added a 5-Amp in-line fuse holder. (….unit claims 3A req’d.)

The media could not be loaded. Easy install... as easy as working on boat wiring could be. Tryed a couple used...like new one first. #1 Used-like new condition, the housing was completely broken in half. #2 Used-like new condition, Fob was missing. Finally I order a new one. Install was easy and simple, took a couple hours but I was taking my time. No problems with packaging or missing parts. Operate as advertised.... dunked tge Fob into a trash can full of water and the engine shut down before tge Fob reached the bottom. Instructions state there is also a wireless connection up to 50 feet. I walk a good 200 feet from the boat and the engine was still running. I pressed the center button on the Fob and the motor shut down immediately, telling me I was still in wireless range.
