The MerCruiser scan tool, a vital tool for diagnosing and troubleshooting marine engine issues, is no longer in production. However, Used Mercruiser Scan Tools, as well as its counterpart, the TechMate scan tool, are readily available and remain highly valuable for boat owners and mechanics. This guide explores the compatibility and functionalities of these tools to help you find the right used MerCruiser scan tool for your needs.
Understanding MerCruiser and TechMate Scan Tool Compatibility
Both the MerCruiser and TechMate scan tools boast broad compatibility with Electronic Fuel Injection (EFI) systems dating back to 1992. This extensive compatibility spans various marine engine manufacturers, including MerCruiser, Volvo Penta, Indmar, Pleasurecraft Marine, Crusader, Marine Power, Kodiak Flagship Marine, and Panther Air Boats, among others. Crucially, these tools require Version 6 software to ensure full functionality and access to the comprehensive diagnostic capabilities outlined below.
Key Features and Supported Engine Systems
A used MerCruiser or TechMate scan tool equipped with Version 6 software offers a wide array of diagnostic features, supporting various engine systems, including:
GM-Delphi MEFI Support (1992-2018)
These scan tools provide comprehensive support for MEFI-1 through MEFI-7 control modules. This enables troubleshooting for a wide range of fuel-injected marine engines utilizing these ECMs.
Volvo Penta EGC Support (2006-Present)
Full diagnostic support is available for Volvo Penta’s EGC fuel injection systems from 2006 onwards, including 2009 catalyst-equipped California engines. This allows for in-depth diagnostic tests, critical engine function monitoring, fault code reading, and access to extensive EFI system information.
Indmar/Zero-Off Support (2008-Present)
Both limited production Indmar engines with Econtrols ECM modules used with Zero-Off GPS speed control and standard production Indmar EFI engines with GM-Delphi marine fuel injection are fully supported.
MerCruiser PCM-555/ECM-555 Support (2001-Present)
Extensive diagnostic functions for engines equipped with MerCruiser PCM-555 and ECM-555 engine control systems are included. This allows for live engine data reading, diagnostic code access, Freeze Frame data retrieval, test execution, engine location setting, and drive trim and trailer limit position adjustments.
MerCruiser PCM-09 (Visteon) Support (2009-Present)
The scan tools support MerCruiser’s PCM-09 ECM module found in 2009 and later engines with catalytic converters, primarily for the California market. Live engine data, including oxygen sensor and catalyst information, fault codes, engine hours, and more can be accessed.
PCM/Crusader ECM-07 & ECM-08 Support (2007-Present)
In addition to GM-Delphi equipped engines, these tools support Pleasurecraft Marine and Crusader’s ECM-07 and ECM-08 EFI control systems, offering full diagnostic functions, engine data monitoring, fault code reading, and EFI system information access.
Additional Support Features
Further support extends to MerCruiser Thunderbolt V ignition modules (1996-present) for engine hour data retrieval, MerCruiser D-Tronic fuel injection systems (1997-present) for live data, fault codes, and engine hours on diesel engines, and various Mercury outboard engines, sterndrives, and inboards.
Choosing a Used MerCruiser Scan Tool
When selecting a used MerCruiser or TechMate scan tool, ensure it includes Version 6 software for complete compatibility. Consider the specific engine models and years you’ll be working with to ensure the tool meets your diagnostic needs. Remember, while these tools are no longer manufactured, a well-maintained used unit can provide invaluable diagnostic capabilities for years to come. Their discontinued status underscores the importance of securing a functioning unit while they’re still available.
