The panel I'm considering is here:
Diesel Engine Marine instrument Panel B type USA Made Alternator Pick Up for Yanmar – AC DC Marine Inc.
There's 6 pages of various Yanmar panels to choose from, and you can completely customize the layout (to include having your boat name lithographed onto the panel). I'll probably use this layout, but am considering white gauges - they really are much more visible. Pretty sure this includes a start/stop switch, though its hard to tell in the photo (but you can add it if its not). ACDC also sells the necessary dual function oil pressure and coolant temp sensors with the correct adapters for the block. I've talked with the owner(?) on the phone and he's very knowledgeable and helpful. Gave me his cell phone and had me send him some photos so he could determine exactly what I would need. The wiring bit was just too much for me so I'm going to need a mechanic to sort that out for me.
I realize its not cheap - but in my opinion well worth it to get actual gauges on the panel. Yeah, I know there's cheaper ways to do it - but those require drilling holes in your cockpit and installing gauges that way. No thanks. Besides, then I'd be back to the wiring issue that I'm not comfortable with.
