I just installed the VesselView Mobile module on the 40-HP [Mercury engine] on my 130 SPORT, and I have been very pleased. I missed the $150 sale that ended March 31, but even at $225 direct from Mercury, I think VesselView Mobile module was well worth its cost. Installation took about 10 minutes. If I had to do the installation again for another boat, the installation would take just a couple of minutes. I use the iPhone iOS app, and I assume the Android app is similar.
I had no idea how many hours were on my engine, and the VesselView Mobile app gives me the hours. The VesselView Mobile app is also great as it shows FUEL REMAINING without having to reach under the seat and feel the weight of the tank. The VesselView Mobile app calculates fuel remaining by using your input data for the starting fuel volume and subtracting the cumulative fuel use derived from the fuel flow.
I saw a post discussing how the fuel flow is measured. I don't know the full details about the fuel flow measurement, but I assume that the engine control unit has a pretty accurate measurement or derivation from some other parameter such as air flow. In any case, it works well.
Since the phone has a GPS receiver to give speed-over-ground and the VesselView Mobile sends fuel flow, a measurement of miles per gallon (MPG) is possible. The app can also provide an estimate of how much RANGE remains based on the current boat speed and engine fuel flow. I really haven't paid much attention to the range remaining, but I find the MPG measurement interesting. I have not noticed any lag in the MPG calculation. As soon as the boat stabilizes at a speed and the engine at an RPM, the MPG is stable.
I found a Bluetooth pairing to be somewhat difficult. I tried to pair the VesselView Mobile module and my iPhone like a Bluetooth headphone through the Bluetooth settings instead of connecting through the app.
I think screen customization in the app could also use improvement. Going back to the main screen at the start of this post, the trick is to tap on the parameters. For example, tap the fuel on the main screen to get more detail. I then tapped one of the parameters, I think it was time to empty, to get more information.
