I am new to the Mecury brand of outboards. I just bought a pair of 1999 OptiMax 225-HP motors. Can I use SmartCraft instruments? I have heard from numerous people that it is not possible, but I have also heard that it is. [Give me] good information about this.

Googling "Mercury Smartcraft" led directly to:

which had a FAQ page:

which answers your questions. Note that they may be talking model year rather than build date.

I was told by an authorized Mercury dealer that there is some kind of in-line connection that will transfer anolog to digital. SmartCraft would then work on the 1999 engine. Have you ever heard of such thing?

I have some [questions] that could be answered by the link to the [M]ercury SmartCraft link, but [I] could not get in due to no username and password. The link to FAQs seems to be for dealers only. My [questions] have to due with Smartcraft gauges on 1998 OptiMax motors

The link given above appears to be gone. The link now redirects to a new resource.

If you have a question, it is simpler to just ask the question than to announce that you have a question. What is your question?

The Mercury website appears to have undergone a revision. The revision breaks all the links given above. You may be able to find the same information by using this new link: smartcraftataglance/technical_information/documentation.php

Many companies outsource their web site maintenance, and when a new vendor is chosen, the old website goes out the window, along with all of its links.

call merc and 920-929-5000 - with your ser #...but I don't think you are compatible as you do not have the correct engine computer in the 99 model....

[Will] [SmartCraft] gauges work on my 1998 [OptiMax] 135-HP? [What] cable do I need? Does the cable have run all the way from the motor [to the SmartCraft gauges] or can it tap-in under the dash?

no - it will not work on your 98's either..

The Mercury FAQ used to show which model years had SmartCraft compatibility. I don't see that information in the new version. I believe that Mercury motors after c.2000 are ready for SmartCraft. A good source of information on this is the owner's manual for a particular motor.

I do not believe that older models of Mercury motors are pre-wired for SmartCraft gauges. Sometime recently Mercury began to incorporate a wiring harness in the standard rigging which was pre-wired for SmartCraft gauges.

The article linked below shows the procedure for retro-fitting a SmartCraft gauge to a motor which was not originally installed with one:

SmartCraft Installation On 2005 130 Sport with 2005 Mercury 40-HP Four-stroke EFI Engine

The SmartCraft gauge installation is clearly shown.

Engines that can use the guages the gents here want to use cary a diamond on the back cowl that says "smartcraft". 99's and priors do not carry that logo - I owned a set of 99 225 opti's so I know of what I speak. I had analog guages and could not mount smartcraft per the techs at Mercury Corp Engineering. In year 2000 they switched to the Motorola PCM 555 computer which allowed the smartcraft SC1000 tach and speedo to be installed. Google PCM 555 for more inofrmation.
