I have a useless gauge on my panel. What to replace it wth?

'75 Starcraft SS. I tore out the speedometer pitot a long time ago, and the gauge has been sitting there dead. Now I'm refurbing the dash panels, and I'd like to replace the speedometer gauge with something cool but wthout making another hole in the panel. It's the standard 3 3/8 size hole. I was thinking a cool digital clock or something, but I can't think of anything useful to put in that hole. Any thoughts?

Consider fuel fumes sensor gauge. One of the most important gauges you can add to your boat anyway.

Do you have a sound machine? This one is out of stock, just for an idea, there are others that fit your cutout - http://www.iboats.com/Milennia-PRV1...117799--session_id.917582315--view_id.1002955

Depth gauge or fuel totalizer

DJ - If I may go off topic for a sec - Where do you boat on Allatoona? The Dead Sea is my home lake and usually drop in at Red Top or ramps to the North.
