Mob+ Wireless Man Overboard System

Excellent . Works as claimed

Great safety product. Clear instructions, very responsive tech support and easy to install and use!

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.)

I want to "love" this product, but I can only give it an "okay", and here's why...Ordered one represented as "new" from TripleNet Pricing. Item swapped right into the hole where my original Mercury kill switch was. While the xFob would "link" to the Basepack, and the Basepack would kill the motor when the button on the xFob was pressed, it would not kill the motor even when I walked up to 100 yards (300 feet) away when tested in the yard. Tested on the water by placing the xFob into a sealed small plastic jar and floating it out on the end of a fishing line, and it still would not kill the motor from 150 yards (450 feet) away. Defective, I guess, so I sent back for refund. (I think they are selling a "used" one now...caveat emptor!)Bought another one from a different seller (FPA Prime Deals). This one had a barcode sticker that also had the words "NEW UNIT" on the packaging, and it included a bag of electrical connectors the first one did not...AHA, clearly I was sold some kind of return/refurb (and still defective) unit by the first seller. Well this second one links up and cuts the motor at about 75 feet on land, about 30 feet on the water, just as advertised. Hooray.So anyway, being that this is supposed to be a lifesaving safety device, is only batting 0.500 something I can really trust? How long until my "good" one eats it?Edit: update 2 years later (Mar 30, 2020), still works like a charm. Now I do “love” it.

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.
