Another possibility would be to find a good instrument panel box from another boat and cut a larger hole.
I'm not too happy with mine either. The gauges tend to fog up in damp weather, and the PO scabbed a fuel gauge into the mix by drilling another hole outside the instrument panel. Plus I get tired of ducking my head down between my ankles when I'm steering, to check the engine temperature. But it's not a super high priority, except I'd like to add a tach.
For those with a plastic cover over the panel, can you easily read the gauges through that?
Down the road, it would be nice to wire up an analog-to-NMEA converter to get the engine data onto the nav monitor, where I can see it (and set alarms.) I found
this one that costs $500, but I think one could whip up the same thing with an arduino board for about $50. If one had sufficient time on one's hands...
