Marine OBD diagnostic tools are specialized electronic scanners, similar to car OBD readers, designed for marine engines (outboards, inboards, jet skis, etc.) to read/clear fault codes, view live data (engine load, fuel flow), perform advanced functions (key programming, throttle reset, injector coding), and pinpoint issues in complex marine systems, using marine CAN protocols for deep-level analysis and maintenance.
