Author Topic:   NMEA-2000: Sample Rigging Prices for E-TEC

Using the Evinrude I-Command Instruments Rigging Guide and Price List, I developed this work sheet for configuring a sample installation of NMEA-2000 gauges on a single engine boat:

[I revised these prices from my original estimate because I was including the cost of a harness which was actually part of the engine remote ignition and trim wiring. This had the effect of making the NMEA-2000 costs be about $200 too high.--jimh.]

SINGLE ENGINE SYSTEM

EMM Harness = $72.67
Power Hub = $99.50
Consolidator = $79.70
Power Supply Harness = $22.67
Data Harness = $42.09
Tachometer Instrument = $379.99

SUBTOTAL for TACHOMETER = $696.62

These prices are based on the individual list prices in the worksheet. It is not known if there will be a package price discount available. Even allowing for a 10-percent discount from list price on the individual item prices, it appears that the most basic installation will cost about $625. With this system, you can display the following information on the single display device:

--crankshaft speed (digital to four digit resolution)
--engine hours
--trim angle
--fuel flow rate
--cylinder head temperature
--battery voltage
--atmospheric barometric pressure
--rate of fuel consumption

With that in mind, the $625 cost does not seem too excessive.

To this basic system we can add a second display for Speedometer and other functions. You must select either a NMEA-2000 Triducer input (which also provides water depth and temperature as well as speed) or a NMEA-2000 GPS receiver which will provide speed and GPS position data:

Speedometer Instrument = $199.99, plus
Triducer = $275.40
--or--
GPS Antenna and adaptor harness = $219.99

SUBTOTAL for SPEEDOMETER
Sonar based = $475.39
or--or--
GPS based = $219.99

To display fuel tank level information, you must add a fuel level sensor and a separate display instrument:

Fuel Level Sensor = $78.99
Fuel Level Instrument = $89.90

SUBTOTAL for FUEL LEVEL = $168.89

If display of the engine's water pressure is desired, a separate sensor must be added to the engine. If a separate instrument is desired, it can be added to show the water pressure value continuously:

Water Pressure Sensor Kit = $177.95
Water Pressure Instrument = $89.90

SUBTOTAL for WATER PRESSURE = $267.85

UPGRADE SYSTEM, consisting of Tachometer and Speedometer:

SUBTOTAL for TACHOMETER = $696.62
SUBTOTAL for SPEEDOMETER
Sonar based = $475.39
--or--
Sonar GPS based = $219.99
-----------------------------------
TOTAL = $1,172.01 for Sonar based
--or--
TOTAL = $916.61 for GPS based

An even more DELUXE SYSTEM consisting of Tachometer, Speedometer (sonar-based), Water Pressure, and Fuel Level instruments would cost:

SUBTOTAL for TACHOMETER = $696.62
SUBTOTAL for SPEEDOMETER Sonar based = $475.39
SUBTOTAL for FUEL LEVEL = $168.89
SUBTOTAL for WATER PRESSURE = $267.85
----------------------------------
TOTAL = $1,608.75

You can work up your own installation and prices using this guide:

Thanks Jim, that really puts things in perspective.
Not too bad if you ask me.

To duplicate the basic Tachometer Instrument I-Command system with traditional gauges, you would need:

--Tachometer ($150)
--Alarm Annunciator ($65)
--Hour Meter ($45)
--Trim Gauge ($45 + sender if not standard on engine)
--Engine Temperature Gauge ($45 + sender)
--Battery Voltmeter ($45)
--Barometer (cost varies; not a common instrument on a small boat)
--Fuel Flow Meter ($200 to $325)

The single instrument replaces seven separate analogue gauges. The estimated cost of the separate gauges is $550 or more, although it is certainly possible to obtain them for less than that, as there are many suppliers and prices are often deeply discounted.

The pictorial diagram below will help identify the components used in the I-Command wiring system:

If you have a single engine installation, you can save a few dollars and simplify the network wiring by replacing the Consolidator ($79.90) with a Terminator Harness ($20.83). This saves about $59. In this arrangement the Power Hub is moved to the helm area, and the Terminator Harness is used at the engine end of the Data Harness.

For folks having a professional marine shop rig their outboard motor and electronics, the plug and play attributes of the NMEA-2000 platform don't offer much of an advantage. However for the weekend boating enthusiast, this type of system makes the proposition of rigging a motor at home much simpler. I'm willing to bet that the yards will still charge the same amount of labor to rig using these sytems, despite the obvious savings in labor that they will realize. One can easily recover the cost of these nice instruments my installing them at home, and saving the rigging costs that would otherwise be paid to the shop.

Very nicely done Jim. I sure could have used something like this when I was setting up my Smartcraft system.

Here are some prices for non NMEA-2000 gauges from Yamaha, taken from their accessories catalogue for 2005. Like the prices I quoted above for Evinrude, these are the MSRP prices. Yamaha calls these gauges their "digital" series, but that refers only to the readout or display. The gauge system uses conventional analog signals and individual wiring to interconnect.

Multi-function Tachometer = $409.95
Multi-function Speedometer = $383.95
Fuel Management Gauge Kit = $620.95
TOTAL = $1,414.85

It is not clear if these prices include all of the wiring harnesses and accessories you would need to install the gauges. You do have to purchase an additional speedometer hose kit to connect the speedometer to a pitot tube pick-up, which I assume is part of the engine. I imagine you would have to construct some of your own wiring to connect the gauges These gauges do not include any GPS information; you have to connect a GPS to them. They do not include any SONAR information. So to get this system on a par with the example above of an I-Command system you will have to add both a GPS receiver and a SONAR depth sounder. This will probably add about $400 to the package. This makes these old-fashioned gauges more expensive than the I-Command series.

Also note that in the I-Command the tank level options can be used for fuel tanks or for oil tanks. You can see the level of the oil reservoir tank(s) in the system.

The only function that seems a bit odd in the I-Command is having to add the water pressure sensor to the system. I would have expected that would be part of the base package. On the other hand, I can see that it would not be needed if the engine is used in a non-NMEA-2000 system, so they don't throw it in.

I have revised the pricing show above to be more accurate. If you forego the consolidator hub and build the simplest and least expensive I-Command installation with just a single multi-function gauge, the cost should come it at around $575 (assuming a little discount from MRSP).

Also, if you purchase a Chartplotter with GPS which is also NMEA-2000 compliant, then you can get the speed data for the separate Speedometer gauge from the GPS, I presume, and so you would only need to add the second instrument ($200), to build a two instrument, Tachometer and Speedometer display system. (However you'd need to add the consolidator back into the system to connect the the Chartplotter device, so add $60 again!) This would cost $830, roughly speaking.

An I-Command system like that would be comparable to the Mercury SmartCraft two-instrument system, which retails for $900 MSRP and probably is available for $800. On this basis, I'd say the NMEA-2000 system is cost comparable to SmartCraft from the published prices.

The real question is when you will be able to actually buy and install all of this stuff. My impression is that at the moment the I-Command products are still in the pipeline between Evinrude and its dealers. It may be a while before they are sitting on shelves at the store.
