December 23, 2025 Merry Christmas and Happy New Year
We would like to congratulate you on the upcoming holidays and inform you that our holiday break will run from December 30 through January 4 inclusive.
Dear friends, our office will be closed from December 30 to January 4 inclusive. All inquiries and orders will be processed on Monday, January 5. Please bear with us - we will be back refreshed and full of energy!
This past year marked our 10th anniversary. It has been ten wonderful years of the best business in the world. We still feel a thrill when we imagine that somewhere right now, on the other side of the globe, one of our devices is conquering the ocean and blinking its green light - and, as usual, we envy it just a little.
This year we finally realized that we have grown up. The main challenges we faced included changes in customs regulations and duties, logistics between five warehouses in different countries, manufacturing injection molds, and fighting for deadlines and quality across two production facilities. There is probably no way to grow up without encountering all these boring adult things.
Not everything went exactly as planned. Due to logistics issues and production delays, we did not release the new line of sensors or the new Ethernet Gateway YDEN-03, which were presented in Dusseldorf at the exhibition in January this year. Nevertheless, the wait will not be much longer!
The new sensors feature Wi-Fi (which can be disabled) and make it easy to configure sensors, view measurement history (Barometer YDBC-06 becomes a real barograph, see above!), and integrate with smart homes or smart boats - all while maintaining the same dimensions and the same power consumption.
This year we also invested a lot of effort into our Autopilot. It no longer requires a rudder position sensor! This not only reduces installation cost but also allows it to be used on boats with outboard engines. The new model will also include Wi-Fi, enabling button-free control and easy configuration for different cruising conditions.
After equipping several small boats, we discovered that our devices are in high demand even on vessels as short as five meters, and we recorded a short video about it.
This year we updated the software of nearly all our products, making them better and better. Among other improvements, we added three new protocols to the Engine Gateway YDEG-04: for Suzuki outboard engines, Hyundai SeasAll inboard marine engines - and even Harley-Davidson motorcycles!
Now it's not only Tesla that can boast a huge touchscreen display. We installed a Raymarine Axiom on a motorcycle and made a fun video about it.
We wish you a joyful holiday season and hope you celebrate happily with your family and friends. Dream big, make bold plans, and bring your dreams to life!
Happy sailing in 2026!
December 10, 2025 Harley-Davidson Support
The Engine Gateway update brings improvements to the Suzuki protocol and adds support for the latest-generation Harley-Davidson motorcycles.
Engine Gateway for marine engines with a digital CAN interface supports more than a dozen different protocols, some of which originated in the automotive market. One of the most popular protocols, J1939, is widely used in trucks and heavy equipment. We also support Hyundai and Volkswagen protocols that were brought into marinized engines from the automotive world.
And now we decided to go one step ahead by adding the protocol for Harley-Davidson motorcycles. Who knows - maybe one day we'll order a luxurious black powerboat lavishly decorated with chrome and leather? In that case, simply add the following line to the configuration file:
PROTOCOLS=HARLEY
and everything will work.
We recorded a video for you showing a Raymarine Axiom marine display installed on a motorcycle, displaying RPM, oil temperature, engine hours, fuel level and volume in the tank, speed (by water, because we are expecting a boat from them), battery voltage, engaged gear, and engine warnings.
We also installed an NMEA 2000 Wi-Fi Gateway on this motorcycle so the rider can switch the Raymarine Axiom into a large-chart mode and at the same time view engine data on a mobile phone via Web Gauges. After all, if he installs a display slightly larger than ours, he won't be able to see the stock gauges located on the motorcycle's tank.
In this update, we improved Suzuki engine support by adding engine warnings (the oil-change reminder is shown as "Maintenance need", and the remaining warnings are mapped to NMEA 2000 alerts in a more intuitive way).
We also added conversion of Suzuki SMG4 data for fuel-tank level and total fuel used. To make Engine Gateway display the tank capacity defined in the SMG4 settings, set TANK_CAPACITY_x to DEFAULT in the configuration file.
To connect Engine Gateway to Suzuki engines, we have prepared an adapter cable (see above) priced at USD $39. It can be ordered from our online store together with the Engine Gateway, and will soon be available from our dealers.
Please note that Engine Gateway does not support the K-Line interface. It cannot replace Engine Interface Cables 99C0-88149-xxx, Engine Connect Gateway 99C0-88171, or the SMD Gateway Unit 34923-96L02. It also cannot replace the Suzuki SMG4 if it is configured for the K-Line protocol (SPC 1.0 engines) rather than CAN.
Our product can replace the SMD Gateway 34923-96L13 and the Suzuki SMG4 display (when configured for the CAN protocol). The gateway is compatible with all Suzuki SPC 2.0 engines (2022 and newer).
Firmware update 1.51 for Engine Gateway is available on the Downloads page.
October 23, 2025 Suzuki and Hyundai protocols
We are pleased to announce that Engine Gateway now supports Suzuki outboard motors and Hyundai marine engines.
To install update 1.50, you must first install update 1.49. After installing 1.49, wait for five short green LED signals and one long signal, after which the device will enter normal operating mode and can be updated to version 1.50 as usual.
We have slightly modified the configuration file. Now the protocols are enabled with a single line. For example, instead of:
MEFI4B=ON
Now you need to specify:
PROTOCOLS=MEFI4B
The following line will be written to the YDEGSAVE.TXT configuration file:
PROTOCOLS=J1939,MEFI4B
The MEFI4B protocol is an extension of the J1939 protocol, so when MEFI4B is enabled, it is added automatically.
We have added comments to the YDEGSAVE.TXT file, so now you will need to refer to the manual less often when configuring the device. We are working on an updated manual that will reflect all the changes in the settings file.
Support for three-phase generators has also been added, and modern Raymarine displays will now be able to provide detailed data on all phases, not just summarized data on average power, voltage, and frequency.
Thanks to our users, we have received Hyundai SeasAll S270 engine records, and now you can see RPM, torque, instant fuel consumption, generator voltage, and coolant temperature on your plotters. We are waiting for additional records from users to add engine warnings and errors and engine hour data in the next product update.
Modern Suzuki outboard motors have two CAN buses. One is connected to the electronic throttle control handle (speed 500 kbps), the other to the Suzuki SMG4 display (speed 250 kbps). The buses have different protocols, and we have added support for both.
The internal bus protocol is enabled by setting:
PROTOCOLS=SUZUKI,OPT1
This bus provides access to engine speed, voltage, trim angle, and gear position. We do not recommend connecting to this bus (4-pin connector with 120 Ohm terminators).
The instrument bus provides access to RPM, instantaneous fuel consumption, coolant temperature, voltage, engine hours, tilt/trim angle, and gear position. We are continuing to research this protocol and plan to add engine warnings and errors.
The connection is made to the tachometer connector (8 pins), and we plan to offer adapters for connection in the near future.
Installing the Engine Gateway eliminates the need to install the SMG4 device and saves space on the boat's dashboard.
We would be happy to add even more protocols to our remarkable device. If you have an unusual engine with a CAN interface, please contact us. Engine Gateway allows you to record data from the engine network on a memory card, which can be used to study its protocol. Engine Gateway can send messages from the engine network to the NMEA 2000 network and vice versa, but unless this is directly enabled by the user, it only reads data from the engine network, which virtually eliminates the possibility of our device affecting the engine's performance.
Firmware update for Engine Gateway is available on the Downloads page.
