I used this depth sounder to replace the depth sounder on my '04 Yamaha SX230. It's a perfect replacement for the original. The original Yamaha branded faceplate and chrome bezel fit perfect. You would never know it wasn't the original by looking at it. One difference from the original is that this depth sounder includes the water temperature, so I had to replace the original transducer and cable also. Before pulling the old transducer cable out, I taped a string to it that I could then use to help pull the new cable back through some pretty inaccessible areas.
I take my boat on lakes that are generally pretty deep; however, if you run in more shallow waters, you'll be glad ot know that the depth on this meter updates quickly.
