I agree with your son on the white gauges. It is what I would have done and it looks great but I was locked in with the style of the black Suzuki gauges.
The Suzuki gauges are like the Yamaha gauges showing the oil levels, warning lamps, etc... and it uses the Suzuki harness that is a hopelessly complicated mess of wires tying all the factory gauges together. When I reinstalled the dash I was more than a little anxious about hooking the right wires to the right connections the number of which was seemingly ridiculous. There was no way I was going to even think of attempting to make a full set of aftermarket gauges work with that motor. So I just replaced the only two non-Suzuki gauges with VDO night series that were the closest match. They don't even hook up the exact same way the older gauges did, actually using less connections but its working (knock wood :lol: )
I had also thought about using white starboard for the dash but figured that it would reflect back sun glare around the gauges.
The gray trim rings were my solution so the black gauges wouldn't visually melt in with the black starboard dash.
Here is what another owner did which is what you may want to do.
You'll notice that on the white panel there are six flat head screws securing it. To me that is kind of crude (sorry whoever's panel this is), I might have gone with an oval head screw with a finish washer.
Before I installed my panel in the boat I laid it on a tub and put all the screws in place to confirm a hunch I had, which was that the panel was busy enough and adding all the stainless hardware would just pull your eye away from the gauges. It also looked cluttered.
So I went with stainless screws with black plastic button covers blending them in with the dash.
You can get them at Home Depot.
Here it is trial fitted, the little tab was trimmed when it was installed.
Compare the button covers below to the screws above.
The Grady White dash plaque can be had on E-Bay.
(again the one on my dash wasn't permanently attached yet so that's why its a little crooked).
I've since affixed it to the panel and yes it adheres to the Starboard like a rock. (clean the panel face first to make sure its free of finger oil etc...)
Looking at the other owners photo you can't help notice the roached out compass. Mine looked like that too but it can be restored.
If you take it out, take the shield off, then with 3M final glaze or even Finesse-it sit down in front of the TV and mindlessly hand buff the plastic with a soft cloth.
It will take a while but it'll come back as good as new!
Mike.
