Mercury & Navico: new VesselView Link, VesselView 702/502 displays and MFD engine interface

... written for Panbo by Adam Hyde and Ben Ellison and posted on Apr 30, 2016

Simrad_VesselView_via_Mercury_VesselView_Link_cPanbo.jpgPerhaps the most remarkable aspect of this collage is what you can't see. There were no Mercury gauges or displays whatsoever on this Navico demo boat thanks to a new Mercury black box called the VesselView Link that offers complete gauge and control integration. Simrad and Lowrance VesselView engine interfaces have also been vastly improved, and Mercury is offering similar full MFD integration on its own new VesselView 702 and 502 displays. So a clean single-brand helm electronics setup is now available under three different brands, and seems reasonably priced even for a relatively small boat. Plus, Mercury offers several other rigging choices including basic NMEA 2000 gauge data output to any brand MFD. Explaining all the possibilities is harder than using them, but let's give it a try...

Actually, a little history is in order, like how Mercury and Navico's relationship predates the Navico brand as we know it! Mercury's powerful though proprietary SmartCraft networking system was first developed by Brunswick's New Technologies group (BNT) which included Northstar, and thus Panbo discussed Mercury MFD gauge integration in 2005. But then Navico was created from the merger of Simrad and Lowrance in 2006, and it acquired BNT's marine electronics assets shortly thereafter. Some of the brands like Northstar and Navman got cut as Navico rationalized its product lines, but at least some of the engineers with SmartCraft integration skills apparently stuck around.


Jumping ahead to 2014, here's a Simrad NSS12 and a Mercury VesselView 7 showing some tight glass-bridge-style integration at the Miami show. Yes, as that entry noted, Navico built the VesselView 7 (and the 4-inch model) to Mercury's specification, each with a SmartCraft port on the back and an internal gateway to NMEA 2000. That (and Ethernet for sharing charts, etc.) is why the MFD can show VesselView engine screens while the VesselView itself can act as a fairly full-featured MFD. It seems like a useful integration, but you still need to have both VesselView and Simrad displays on the boat, and that's what's about to change in multiple ways, thanks to the new VesselView Link, 702 and 502 products detailed below.


First, though, let's review what Mercury can do with standard NMEA 2000. When the MercMonitor came out in 2009, one noteworthy feature was an included gateway to any N2K MFD or instrument display that understands PGNs (Protocol Group Numbers) for RPM, oil pressure, etc. So you can use the Monitor mainly to control SmartCraft features like Troll Control, while the gauge data shows on a bigger, more colorful screen (perhaps with advanced gauge designs and alarming). MercMonitor is still available, and at the bottom of its page you'll find a link to the standalone N2K gateway above (PDF here). Note, though, that the separate single and multi-engine gateways have been superceded by one model (part # 8M0105243) as shown on this third party Verado site.

While the NMEA 2000 standard does include common engine control commands, engine manufacturers have avoided them, which seems understandable given the technical and liability issues involved. Standard N2K engine commands probably don't include nuances like SmartCraft Smart Tow either. So what we've seen is partnerships like the Volvo Penta (Garmin) Glass Cockpit, which still use N2K but network critical commands (and deep info-like fault messages) using proprietary PGNs. Now let's see how the Mercury Navico integrations have evolved...

Mercury VesselView Link


Until now boaters with Mercury Smartcraft engines needed a SmartCraft gauge or display to get full data and control functionality from their (40HP and up) outboard, sterndrive or inboard. Shipping in June, VesselView Link is a complete Smartcraft to N2K engine gateway that enables a complete engine interface on certain Simrad and Lowrance MFDs (and also on the new Mercury 702/502 VesselView displays). Boatbuilders can free up valuable dashboard real estate with either the VV Link single engine (#8M0110639) retailing for $615 or the multi-engine version (#8M0110641) for $1200. That means a single outboard boat with a single Lowrance HDS-7m Gen2 Touch will have glass-cockpit-style engine monitoring and management for about $1,314 retail (not including boat and motor).


Here's a Lowrance HDS 12 Gen3 showing some of the new VesselView Link engine interface features that will be included in Lowrance and Simrad software updates purportedly coming in June. Note that you can now show the gauges in a window, not just full screen as used to be the case with the V7/V4 integration. We have more about the improved interface further down the entry.

VesselView 702 & 502 MFDs


Mercury also introduced two new VesselView displays at the Miami Boat Show including the 7-inch 702 above. It's like v2 of the older VesselView 7 it replaces, except that now the SmartCraft gateway duties are handled by a separate VesselView Link. And the 702 isn't just built by Navico; it seems to be a rebranded Simrad NSS7 EVO2, while the new 5-inch touch-only 502 below seems to be a rebranded Simrad GO XSE. The new VesselViews come bundled with single or multi-engine VV Links, with the 702 retailing for $2,156 single or $2,581 multi, while the 502 is $1,576 single or $2,001 multi. The 702 package includes an external GoFree Wifi1 module, while the 502 has WiFi embedded. (The 2-engine capable VesselView4 will continue to be offered, though with its different software interface and its built-in SmartCraft gateway.)


The VesselView 702 and 502 models are fully capable MFDs with built in GPS and support for options such as radar, AIS, sonar, digital switching, audio control (Sonic Hub2 or FusionLink), etc. Both displays support GoFree cloud updates and Walter Ross -- a senior product manager at Mercury Controls & Rigging who helped a lot with this article -- said:

What I'm most excited about is the ability to easily distribute these software updates (which we release about twice a year, to include new features, functions and any bug fixes) and also the ability to offer advanced features for Mercury propulsion systems as DLC (downloadable content) from the GoFree store. We have the potential to offer an upgraded or advanced feature to a wide range of users. That's just cool!

What's the takeaway so far? SmartCraft descriptive fault codes, comprehensive engine data and digital propulsion control features such as Cruise Control, Smart Tow, Eco Mode and Troll Control (in 10 RPM increments) will soon be available on Mercury, Lowrance, or Simrad MFDs without other helm gauges or displays at a lower total cost than previous options.

Why use Mercury MFDs instead of Simrad or Lowrance? That might be the choice of a boatbuilder wanting engine and electronics all one brand, or a big boat that wants VesselView as a full featured engine display with navigation backup capabilities.

New VesselView interface


The new VesselView interface -- seen working splitscreen above with four SmartCraft outboards -- seems to be very similar on all the Simrad, Lowrance, and Mercury displays where it will run. Simrad VV Link models are here with other details and similar Lowrance VVL specifics are here.


One feature of the new interface is quick access to numerous popup info screens simply by tapping on the main guage window. If you want more detail on engine trim, for instance, you just tap on the trim icons seen at the bottom of the main engine window. It's easy to remember! Note that these screens were taken during the Navico writers event in January (also seen in the top image) and the video below was shot on the same triple-engine boat.

The Simard VVL video nicely shows how VesselView can be added to a multi-window screen layout and also the Quick Access Bar that can always be available regardless of the screen layout (which is also seen on all the screens above). Tapping "Mercury" gets you a narrow but informative engine data sidebar and tapping "Vessel Control" gets you to Smart Tow, Eco Mode, etc. all nicely illustrated in the Mercury VesselView 702 quick guide snip below.


The Lowrance VVL video below illustrates the new VesselView interface working with a single engine. And note that engine-related notifications purportedly pop up regardless of what else is on screen, though, as usual, alarm parameters cannot be adjusted. Ben has been lobbying for custom engine alerts based on values like coolant temperature so far to no avail, but Mercury's Walter Ross pointed out that:

The user can adjust the engine parameter limits, though, and that adjusts the scaling of the data that gets displayed (and what you may consider "red" before the alarm goes off).

Apparently, this was also a little known feature of the original VV7 and VV4 displays whereby you change the preconfigured limits so that you will get a visual indication if, say, your coolant temperature goes higher than what you define as normal (and we'd like to see how it works). And here's another valuable pro tip from Walter (though you may need a notebook near the helm):

I monitor seawater pump pressure (aka coolant pressure). I know what that nominal value is when I'm at idle and at every 1000 RPM increment. When it drops off more than 10%, I change the seawater pump impeller.

At any rate, Walter's enthusiasm about all the ways Mercury and Navico are now working together seems completely justified, and we suspect it will spread into the boating world rapidly once all these products become available.


"Hello, is this Mercury or.....?"

"No sir, you've reached Navico Customer Care phone support".

"Well, I need somebody to come to my boat and fix the Gauges from my Mercury, The Mercury dealer told me to call you guys because I guess there is some kind of UPDATE... because it keeps telling me I have no outboards on the back of my boat......I cannot see any of my gauges and I have a big trip tomorrow"

I honestly can see this happening.

My point is integration is great, but some integration is best left un integrated.

Excellent article and very timely as I've been considering upgrading my Garmin 740S.

Will this new gateway support older SmartCraft products. I have a single Verado engine with DTS and SmartCraft gauges with a build date of 2008. It would be nice to move to a Simrad MFD and the new gateway if my older system and the new products are fully compatible.

The other lonely orphan out there is the Cummins version of Smartcraft displays, which date from the short-lived romance between Mercury and Cummins. Trying to set up a NMEA 2000 interface for Cummins QSB Diesels back in 2012, I played ping-pong between Mercury and Cummins until finally I just decided to buy the prior Mercury multiengine NMEA2000 interface and try it, which fortunately did work to everyone's surprise. I was able to see all of the engine and gear PGNs on my Furuno MFDs.

The new Garmin 8600 series has a J1939 port which in theory should allow a direct connection to the engines without an interface. I have not heard of anyone actually using this yet or what data makes it across.

Thanks, Quitsa. Plus "we learned in Miami that this J1939 port will soon be included on new Garmin 7400/7600 MFDs (as a rolling change that will not effect prices but will get new part numbers)...

I recall that a Garmin guy said they were trying to work with all the engine manufacturers who use J1939 to display as much information as possible, but I don't know what that means in practice.

Butch - from Walter at Mercury:

Yes, this new VesselView Link will support ALL SmartCraft capable engines circa 2007 and newer (diesel, OB, MerCruiser, Zeus and Racing); obviously has to be paired with a compatible display. We know it will work all the way back to 2004 SmartCraft engines but some functionality may not work correctly (as all the current features were not available that far back).

I will be able to get a first hand test in another month or so when my new boat is completed as I will have a pair of Garmin 8617 displays and Cummins engines. The engine displays are a third party J1939 display, not Smartcraft, and they have a built in NMEA 2000 output. However, it should be easy to plug the J1939 cable into one of the Garmin MFDs and see what comes up.

Speaking of which, let me know when the time comes if you want me to venture into journalism again once I have a chance to use the 8617s in the field. I may have a Fantom 6 radar but then again I am leaning to the 25kW magnetron unit given my suspicion that the Fantom won't be as good at spotting birds at long range, more like a 6kW magnetron unit performance.

Thanks, Quitsa, it would be great if you wrote again for Panbo and I'll email you direct.

Ben...thank you for another great posting.
With each update from Navico, I am seeing the real capabilities of the technology come out. Three years ago, I ran the boat with a separate PC with showing Maretron's N2Kview. The last year, I have configured most of the NMEA2000 data to be displayed in the data bars on the NSO Evo2 screens. The limitations I am seeing now is the limited PGNs coming from the Maretron EM100. I would like to see Simrad create some additional graphical presentations of the data bar data - for example the Wind Speed / Direction graphs and direction compass rose instead of just numbers. Having a red arrow pointing and swinging is much easier to understand than numeric display.

Jerry, John Scott from Navico responded to your comment (and it's useful info for anyone using the new SmartCraft integration):

"If it has a Mercury logo on the front of the display Mercury should be called. If it has a Lowrance or Simrad logo on it, Navico should be called. The code is the same so if there is an issue it will appear the same regardless.

I would like to highlight that one of the biggest steps forward recently in Navico is the ability to get diagnostics & live updates to address exactly this issue. Connecting your VesselView 502 or 702 to the internet will automatically check for software updates, notify the user one is available, and then give the option to download it. Check out

The most likely fault would be a communication error, which would be shown as “No comms” on the display and which indicates no communication to the engine from the VesselView Link. The most likely cause of this would be install error or lack of SmartCraft network termination.
On a Navico MFD, if the Mercury user interface does not show up, it indicates the MFD can’t see the VesselView Link gateway on the network, this indicates a problem on the NMEA2000 bus.

If all this fails you can send Navico a fault report directly from Simrad & Lowrance units

Quitsa, Navico's John Scott also replied to your lament:

"VesselView Link will work with Cummins SmartCraft engines. Cummins engines output either J1939 or SmartCraft. They are not to be confused; J1939 is different from SmartCraft. All SmartCraft engine owners old & new benefit from the advanced integration. The new user interface looks the same but is tailored to the diesel limits and functionality of Cummins engines."

Strictly speaking, I am pretty certain that only those Cummins engines that were configured for use with Smartcraft displays and have a Smartcraft interface box that outputs data in the priprietary Smartcraft format.

The Cummins engines for my new boat were ordered as pure J1939 and have a lot less cabling and one less interface box than the engines with Smartcraft displays in my old boat. They will be used with a J1939 display from another supplier.

So Mr. Scott's comment is correct for a Cummins engine that was delivered set up for Smartcraft displays. However, by removing the extra interface box and some reconfiguring of the cables, that same engine can be used as standard J1939, which is its "native language."

I have got connected with HDS gen3 Mecury four stroke 115 with mercury NMEA 2000 gateway. All data is visible, except engine trim.
Can I get advice why this is so.
And , can I manage RPM / trolling / only with NMEA 2000 gateway.

Not sure on the engine trim question. The N2K gateway won't control the engine or give you the full Smartcraft feature set, for that you will need the new Vesselview Link and a software update for your Gen3 when they are available in June.

We missed the March 4 announcement that Mercury Marine will offer a Bluetooth module and apps that can put VesselView on your Android or iOS smartphone or tablet...

...but can anyone find the apps that were supposed to be available in May?

Hard to find clear information here in EMEA:(.. Mercury is saying that we can plug sonar and structure scan on the VV702 because this is a Simard NSS 7 evo2 and it includes sonar broadland... but in the documentation it seems this is wrong.
Any confirmation you could give me would be appreciate

Exactly which documentation are you referencing, Jerome, because I think that Mercury is correct? Please provide a link if possible.
