OBDSTAR (M083) | Universal 9-pin OBD - 16-pin OBD2 Adapter Cable | Motorboat

$25.85

The OBDSTAR M083 is a universal 9-pin OBD to 16-pin OBD2 adapter cable specifically designed for diagnostic applications on motorboats and marine diesel engines. The cable connects a round 9-pin diagnostic port — as used on marine and industrial engines — with a standard 16-pin OBD2 J1962 connector, allowing OBDSTAR readers or programmers to be connected to these vehicles. The cable is compatible with engines from brands such as Cummins, John Deere Marine, Kohler Power Systems, VM Motori, and Cummins MerCruiser Diesel.

The adapter cable converts the 9-pin round connector format to the standardized OBD2 format, allowing the OBDSTAR diagnostic system to access the communication lines of the engine control unit. Signals such as K-line or CAN-bus are routed through the connected diagnostic port to the reader, which can then read fault codes, sensor values, or retrieve system information. The pin configuration of the 9-pin connector is specifically tailored to the marine applications for which this cable is intended, ensuring the correct signals are transmitted without the need for additional adapters.

ADVANTAGES

✔ Enables direct connection between a 9-pin marine diagnostic port and a standard OBD2 J1962 connector without additional intermediaries.

✔ Supports multiple marine engine brands, including Cummins MerCruiser Diesel, John Deere Marine, Kohler Power Systems, and VM Motori.

✔ Specifically tailored pin configuration ensures correct signal transmission of CAN-bus and K-line communication lines.

KEY POINTS

✕ Only compatible with OBDSTAR readers or programmers; not usable with diagnostic systems from other manufacturers.

✕ Not intended for use on passenger cars or trucks; the cable is specifically designed for marine and motorboat engine applications.

✕ The available diagnostic functions depend on the OBDSTAR device used and the support per engine brand in the accompanying software.

Applications and functionalities

The OBDSTAR M083 Adapter Cable enables the following diagnostic applications on compatible marine engine systems via OBDSTAR readers:

Reading and clearing fault codes: The reader retrieves active and stored fault codes from the engine control unit (ECU) of the motorboat engine and can clear them after diagnosis.
Reading live data: Real-time sensor values such as engine speed, coolant temperature, and fuel pressure are read from the 9-pin diagnostic port and displayed on the device.
Marine ECU system diagnosis: The Adapter Cable provides access to the control systems of the marine engine, allowing identification of drivetrain system faults.

Compatible vehicles and applications
