My specific Dolphin complaints:
- chrome bezels on two gauges starting developing rust pits after less than a year.
- water temp gauge was off by 20 degrees (low).
- fuel gauge would hang at about 1/2 tank. Tapping on the gauge would free it up.
- I could never get the speedometer programmed to show the correct speed. Dolphin uses DIP switches and a data table to (supposedly) enable one to set the correct speed. Never got within 10 mph of correct.
When I would call their tech support line, I would usually get the message, "All of our lines are busy right now, please call back later," or words to that effect. The few times I actually got through, the tech had an attitude and was not helpful at all. Exact same experience with EZ Wire tech... may have been the same person!!
