1. Depending on the gauges selected the water is either the water pressure line, or speedometer tube. If the boat has SmartCraft it’s all digital and should have no hoses to leak.
2. This probably needs another spacer block on the latch lip. They are set and hard mounted, though can be tweaked with some understanding of the mount.
3. It could be that USB port as some are not the originally 2022 chosen port, and it could just be a bad port. Supply chain issues had us opt for another brand. Due to that the USB power adapter possibly was not wired in house as we had several recently awaiting that one part. Those were installed after production and our initial thoughts could be the later installers missed wiring those up. They possibly had already been through final prep and checkout, just waiting that one part and it wasn’t final checked by the installer. The power switch should control this and it could be a stereo model also if you have a stereo.
Sorry for these issues and you have some things to be addressed.
