The kit worked fine and my Hummingbird transducer fit flush as advertised. I didn't need the power cord as my Hummingbird fish finder had one. The only negative is the instructions didn't cover all steps. The wing nut is somewhat hard to tighten as it is deep in the scupper and depending on how big your hand is it can be difficult to reach. Rated 4 stars because of poor instructions.
