That is the extent of their testing really. Now, most the gauges have staining on the inner lens.To repair the lens has to be removed. The fascia is in pretty decent shape, with no cracks, and the switches all work. Without properly testing the gauges, I cannot say for certain they work. All, one, or none may be properly working. Obviously these gauges are not cheap, and i'd far prefer to sell working individually. If I get a fully functional boat to test them on, I will do so and will change the listing. If this ad is still listed, then this is the ONLY way I will sell them. I will not separate anything. W hat you see is what you will receive...
