Mercury Digital Diagnostic Tool

This hand held Scan Tool is easy to use.
The flexible sealed keypad, rubber boot and rugged
design will provide many years of service. It comes with a 10-foot (3 m) cable.
Adapter cables are used to connect the DDT to Data Link Connector (DLC) on the engine.
There are separate Cartridges for Mercury/Mariner Outboards
and MerCruiser products. Instructions with the Cartridges and Service
Manuals will tell how to connect the DDT to the engine.

The DDT, when used with the correct cartridge, and the products Service Manual will allow
the technician to properly diagnose and repair engine systems. Engine functions can be
monitored while the engine is running to aid in diagnosis and will display any stored trouble
codes. On MerCruiser engines, the DDT is used to set the base engine timing on
MEFI-1/-2/-3 ECM models.


UPDATE... As of 11/2006 the DDT is NO LONGER SOLD.
