I use this diagnostic interface on my Yamaha Outboard F225TXRB 2003. It provides me with the data I need. my Yamaha gauges on the boat have long given up. I use the CANDOO PRO for faults, numbers of hours on the V6 and temperature readings. I would like to permanently mount a small laptop at the helm and do away with the Yamaha gauges. I would loose engine tilt reading and fuel capacity. I would install a fuel gauge (99 gallons). Love this unit!
