The Garmin Yamaha Engine Bus to J1939 Adapter Cable (010-12770-00) is a marine interface cable that ties a J1939-equipped Garmin chartplotter into a Yamaha engine bus multi-hub. It's built for boaters running Yamaha power who want engine data shown directly on a compatible Garmin display. The adapter handles the protocol handoff between the Yamaha bus and the chartplotter, opening up Yamaha's fully-integrated boat control system and its custom touchscreen engine interface. If you're building out a helm with Garmin electronics and Yamaha outboards, this is the piece that links the two. Browse our full range of marine navigation instruments to round out the install.
This cable carries the J1939 protocol standard, which is how Yamaha's engine bus communicates fuel level, trim position, engine speed and other metrics to the chartplotter. Per manufacturer specifications, it's compatible with J1939-equipped Garmin GPSMAP 7400, 7600, 8400 and 8600 series chartplotters. One detail worth knowing before you order: the adapter requires a separate Yamaha pigtail bus wire, sold separately in lengths from one to twelve feet, so you can match the run to your console layout. Once wired in, the Yamaha touchscreen engine interface appears on the Garmin screen, giving you a single point to read engine status without a dedicated gauge cluster. Pair it with the right cables and sensors for a clean network.
A boater stepping up from analog gauges to a Garmin glass-helm install needs this adapter to bring Yamaha engine telemetry into the system. It fits center-console and offshore rigs where the chartplotter doubles as the engine monitor, freeing up dash space and keeping all data on one display. Plan the pigtail length around your rigging tube routing before final assembly. For the rest of your build, look at our GPS chartplotters and supporting marine accessories to complete the helm. We stock Garmin interface hardware to keep Yamaha-powered boats fully integrated.
It connects a J1939-equipped Garmin chartplotter to a Yamaha engine bus multi-hub, letting Yamaha's fully-integrated boat control system and custom touchscreen engine interface display on the Garmin screen. This lets you read engine metrics like fuel level, trim position and engine speed directly on the chartplotter.
Per manufacturer specifications, it works with J1939-equipped Garmin GPSMAP 7400, 7600, 8400 and 8600 series chartplotters connected to a Yamaha engine bus multi-hub. Confirm your unit is J1939-equipped before ordering.
No. The Yamaha pigtail bus wire is sold separately and comes in lengths from one to twelve feet. Choose the length that matches your console routing so the run reaches cleanly from the engine bus to the adapter.
