Smartcraft for Mecury 115 HP engine

posted 02-12-2008 10:56 AM ET (US)
I am interested in installing Smartcraft gauges on my 2007 160 Dauntless, which came with the newest 115 HP FourStroke (hope I got that right...). I currenly have analogue gauges for the Tach, Water Pressure, Volts and Fuel Level. I have spent hours on the Smartcraft website and am frustrated by the lack of information and inconsistent informaton. Anyway, I am trying to understand what signals my specific engine provides through the Smartcraft harness. The confusion starts with the following page from Mercury Marine:
It lists the signals from the various engines, but does not even include the 90 or 115HP Four Stroke engines. I need to know this in order to understand the gauges I need to add and replace.
1) Does anyone know what signals the 115 Four Stroke engine sends to the Smartcraft gauges, similar to what is shown on the web page above?
2) Does anyone know if the signal for the "Fuel Level" on the 160D goes through the Smartcraft harness or if it is a separate signal directly from the fuel tank? I need to know in order to determine if the current Fuel gauge can be replaced with the Smart Link Fuel gauge.
I have contacted Mercury Maring, with no response so far.

Mike, I hope someone answers your question. I also have found that Mercury's web site leaves a lot to be desired.
I have the same engine and my dealer said that the engine doesn't support Smartcraft. I emailed Mercury my serial number they said it does support Smartcraft.
I want to change to the Smartcraft SC1000 System Tachometer. Can you leave the rest of the original analog gauges?

It is amazing the confusion from Mercury and or the dealers on these engines. We have to accept that we can no longer refer to them as a year model...ok. However, it is not acceptable that a question as simple as whether an engine supports their own proprietary Smartcraft system cannot be answered. For the 115HP engine we have, your dealer says NO, Mercury says YES. The Mercury website says NO. My same inquiry to Mercury with my serial number by phone says YES. A followup email goes unanswered, so maybe no one knows.
All I want to do is spend more money on Mercury "stuff" and I can't do it. No one seems to know what is going on. Too many questions.
Ok, calmed down now....

According to the literature from Mercury
"NOTE:This section shows all of the display screens that are
I guess the real problem here is finding that list of what engines support what "screens."
Now here is a nice graphic table what shows what engines support what "screens," but it does not mention the 115-HP FourStroke.
But it just points back to the incomplete graphic that doesn't list your engine.
I can appreciate your frustration. I can't find the answer on-line, either.

if calling customer service at 920-929-5000 and your ser # does not work, Find a big dealer around you that sells mercury and does a lot of repowers..Sundance Marine in fort lauderdale is one. They have a internal tech hotline that they can call and is staffed by hotline engineeers that have all the answers...good luck....

It will show:
It will not show the following:
There are accesories at additional cost that add some features like remaining fuel level, boat speed, Etc...

Thanks very much for the additional information. I just received a response from Mercury Marine to some of my questions. I have parsed the response as follows:
Re: Mercury 115 EFI 4 Stroke
Thank you for your e-mail regarding your Mercury 115 EFI 4 stroke motor, serial # 1B508889.
Your motor will need a SmartCraft Conversion Kit, part # 889250K01 suggested list price $211.42. This will then give you the same information as available from the 75-115 OptiMax. See link below:
If you wish to use some of your existing gauges, after installing the SC Conversion Kit, you will need to install an Analog Gauge Interface, part # 892486K08, suggested list price $129.41.
The SmartCraft information will then travel through your 14 pin boat harness, if the boat is 2006 or newer. The plug at the key switch will plug into a Junction Box, part # 878492K14 (w/2 weather caps), suggested list price $62.17. The System Tach and Speed gauges, together, have a suggested list of $828.25 (these do include a j-box). The System Tach, by itself, has a suggested list price of $358.75.
Given the above, and looking at the referenced chart, it looks like the signals will include:
If what they are saying is correct, it will NOT inlude Oil Pressue or Oil Temp.
This is all very important information that can now be used in designing what I need to do to convert at least some things to Smartcraft capabilities. As noted earlier, I now have only a Tach, Water Pressure, Volts and Fuel Level gauges.
Given the information above, I am thinking of changing my current Tach to a Smartcraft System Tach, and keeping the current Water Pressure, Volts (+/-) and Fuel level.
The only other question I have is whether I have to use the Analogue Gauge Interface if I don't change the exisiting guages to Smartcraft gauges.
Anyway, I feel like I am now getting somewhere. If anyone has any suggestions about my current strategy (Smartcraft Tach, keeping the other gauges), let me know.
Sorry for taking so much bandwidth, but it might help others with this engine. Also, there remain some descrepencies in information, so if anyone learns more, please keep us updated. I will do the same.

Mike, I have the Smartcraft Tach. It has the Troll Control. I kept all my other analog gauges with no alterations. Personally, I would not get the Smartcraft Speedo, as you have GPS in most cases anyway. I ordered mine through Livorsi Marine. The have very good prices and are very knowledgeable about Smartcraft. It's a simple plug and play procedure. Plug one end of the harness at the engine and plug the other end into the gauge and your set. It will show oil pressure, but I errored when I included oil temp. It will not show water in fuel unless you get the sensor. I would go with your strategy and just get the Smartcraft Tach....

Here is the email response that I got from mercury:
Mike - Do we have the same model engine?
Comparing the two emails it is unclear whether I need all of that stuff that you were told that you need, or does your engine not have a SmartCraft compatible ECU?

It looks like your serial number is earlier than mine, but it does look like the same engine. While both our engines are "Smartcraft capable", they are not wired for Smartcraft capability to the gauges at this time. The components Mercury gave me is what it would take to transmit the signals from the Smartcraft capable engine and transmit them to the gauges.
Based on dbrown's response, which by the way is very helpful, it looks like he has done exactly what I intend to do....install only the System Tach. In his case, it looks like I can just run the harness from the engine directly to the System Tach, and keep the other 3 gauges alone. I can use my GPS unit as the speedo. If this is the case, I will be REALLY HAPPY!

Here are a couple of interesting threads. I found them doing a search on Google of "SmartCraft Conversion Kit"

Definitely the newest engine...it came new on my 2007 160D.

Mike, I have the 07' Manufactured 90 HP FourStroke model, which for all intents and purposes, is identical to your 115. They are based on the Verado and are Smartcraft compatable. It really is as simple as buying the gauge, harness and plugging it in. You will leave all your other gauges as they are. So don't worry, be happy. My cost in the spring of 07' was $257.00 for the gauge (SCS7000 Smartcraft Tach) and $79.00 for the 2 resistor harness (SCH2R20)(20'). You would need exactly the same set-up. Doubt if it has gone up too much in the last year.

Thanks very much. Your setup is exactly what I was looking for. It took a bunch of messages to get to this point...
I went to the Livorsi website and downloaded their catalogue. They have some really cool stuff. It seems they are also in Grayslake, IL, which is no more than 30 min from where I live in the NW suburbs of Chicago.
Again, thanks for all the help. I'm set.

Mercury SmartCraft has new literature which now gives the information being sought in this discussion:
SmartCraft "screens" available with the FOURSTROKE 115-HP and 90-HP Engines include:
--Engine speed (RPM)
This new literature was being distributed at a recent boat show. As of this writing, the SmartCraft website has not been updated with this new information in the graphic mentioned above. Please use the above list as an authoritative source. It is taken directly from the Mercury Marine SmartCraft literature.
