Mine came with Teleflex Sahara gauges; searching for that gives tons of hits like
this or
this.
The only real issue with this kind of swap is the speedometer - need to choose an appropriate max speed (0-50 works well for our boats), and the type of sensor. For example, mine uses a paddle wheel for speed pickup, but all the current models that Teleflex sells use a pitot pickup.
Is the problem that your gauges all died at the same time, or just that they look ugly?
