They are specifically written for the do-it-yourself-er as well as the experienced mechanic. Mercury Outboards – Durable. To order a printed version of the Service Manual for your particular Mercury Outboard. ECM 555 W/Knock Control. Your Mercury MerCruiser PCM 555 Diagnostics (SN 0M000000 and Above) parts correspond with the number of pages printed on it in this manual, very easy to use. Mercury MerCruiser PCM 555 Diagnostics (SN 0M000000 and Above) Service Repair Factory Manual is a perfect manual, which contains a lot of information. I believe that would be what you need.
Here is an example of wave foam testing by us on a MEFI 3 ECM to show that we will work on a variety of different ECM units. If you are doing an engine rebuild, engine upgrades, or maybe just trying to find your engine running issues, ECM testing is one way to help diagnose your issues.
Also, if you are doing recalibration to your ECM, it is very wise to have your ECM tested before recalibration. You must have a good working platform at the onset of your project BEFORE you think about using your 10 to 30 year old ECM unit, especially on newly built engines or upgrades.
Why would anyone want to risk having a faulty ECM jeopardize their investment, especially when the electronic ECM is old? ECMs are a very specific electrical processing device receiving inputs and controlling outputs.
Just like anything else electronic, ECMs will fail in due time. Please see the gallery below.
— The first picture is the wave form patterns of a bad ECM.
— The second picture is that same ECM fixed by Boats Unlimited. The wave form patterns now show steady normal patterns.
— The third pic is the internals of this same MEFI 3 ECM with some marked components and the red dots that are common failure points. We see these failures on a daily basis.

Max Volt Catalyst Eliminator ComputerMax Volt Catalyst Eliminator Computer If increased engine performance is what you are after but have concerns about the catalyst equipment on your engine, then the Catalytic Eliminator Computer (CEC) is what you need! Designed specifically for marine engines, Maxvolt Performance worked with a team of marine electrical engineers to create a product this simple and gets the job done. There is no cutting or splicing of wires; everything is plug and play! And there are three ways to play! Your engine can be Aggressive,Mild, or Basic: Aggressive: If you want to be aggressive and replace your stock exhaust system with a header system, then this is the product for you. We worked with the header design teams at Hardin Marine and other popular manufacturers to be sure their headers are manufactured to work with CEC. To be compatible, the header must be made to accept a pre-oxygen sensor! Mild:If changing over to headers is too aggressive for you, then removing the catalysts but retaining the stock exhaust manifolds is the path for you. Depending on the engine, 10 to 15 horsepower will be gained by removing the catalysts and using the factory exhaust system. Basic:If your boat has fouled its post oxygen sensors and is no longer under the factory warranty, then you know what it costs to have new sensors installed and the trouble codes cleared. For less than what your dealer charged, you can purchase and install the CEC and never have to worry about throwing that fault code again! Note:
WARNING! This module is not to be used on emissions regulated waterways. The intent of this module is to allow the running of a catalyzed marine engine without the catalytic converters installed and without triggering any ECU error codes. With the engine operating in this condition, the emissions control system will be rendered inoperative. For this reason, do not operate the vessel on emissions regulated waterways. This computer system is not legal for any purpose other than testing purposes and not for use on any state or federal waterway. |

IAC Survival KitThe Marine Design Corporation IAC Survival Kit is designed specifically for Mercury Racing 600SCi, 662SCi and 700SCi engines. Our kit eliminates costly PCM damage that can occur when an IAC fails, which can be a common occurance. The kit was developed for twin engine applications and includes two plug-and-play IAC harnesses that are fused to prevent a direct short to the PCM. Also included are two USA made IAC units with gaskets, hardware, (just in case you drop one in the bilge) spare fuses and a canvas storage pouch. Replacement IACs and fuses are also available. |
