I am currently developing a small electronic product that retrieves data from your boat engine's computer (ECM, ECU, etc) and broadcasts it on your NMEA2000 compatible network so that it can be displayed on your GPS/Multi-Function display.
The installation is easy. Simply plug it into the engine's existing diagnostic 10-pin plug and connect the other end into your NMEA2000 compatible network using the supplied T-connector and drop cable. Thats it. Now you'll have engine data on your GPS updating once per second.
What engine data is broadcasted? Fuel Flow Rate, Engine RPM, Engine Coolant Temperature, Engine Run Hours, Battery Voltage, Various Alarms (High Engine Coolant Temp, High Exhaust Manifold Temp, etc).
What engines are compatible with this? Thats a great question and I need your help to find out. I designed my product to be compatible with my 2002 Four Winns 268 Vista which is powered by a single Volvopenta 5.7gxi-b using a MEFI-3 ECM model #16237009. The MEFI-3 ECM is made by Delphi and is used with many other engines including Mercruiser as well.
There are several different model numbers associated with the MEFI-3 ECM and I want to make sure my product is compatible with all of them. Additionally, the MEFI-4 shares many similar characteristics to the MEFI-3 and would likely be a good candidate for a future version of my product.
Who am I? My name is Allen Murrow and I'm a Nuclear Reactor Operator for a local power company. I happen to have a broad range of interests and hobbies that made developing this product challenging and fun, but most importantly, achievable. I dabble with computer programming, websites, microcontrollers and electronics, machining (lathe and mill operations), welding (MIG, TIG, and Stick), hydraulic equipment repair, and boating.
I expect to sell my product for about $210 each. This price will depend on the demand though. If there is a high enough demand, I may be able to get a much better deal on the individual components and circuit board printing.
The purpose for this post is to gather data on the number of people interested in purchasing this product. I would also like to hear from those who would want to help test this on their MEFI-3 ECM and I would like to hear from those who would be interested in a MEFI-4 version.
Please understand that I do not run a business. I have a personal life with my beautiful wife and an adorable 1 yr old daughter (and a Rottweiler, a Pit bull, and a Great Dane). This product does not yet come with any warranty nor do I assume any responsibility for any potential damage occurring during its use. This product only suggests that it is "compatible" with your NMEA2000 network and devices. It is not NMEA2000 "certified", "approved", nor any other word that would lead one to think that I would be required to pay a license fee for its use. All of the technology used to create my product was publicly and freely available on the internet. The goal for this project was to produce an affordable product in our overpriced marine electronics industry while attempting to earn some startup capital to create a small Research and Development business to pursue additional marine electronics products and technologies. Eventually, I plan to seek certification from the National Marine Electronics Association.
Thank you for your support.
