Re: Replace speed/depth display
I've had three generations of Authohelm/Raymarine instruments on my 1990 vintage sailboat. Replacements occurred in 2000 and 2010, thanks to lightning strikes. The displays were on a spray hood, under a dodger, and were always covered when not in use. All of the displays were looking like new just before they were replaced
Each successive generation had better display visibility, particularly at night. I'll bet you'd be pleased with a new display.
If you decide to replace vs. repair, you should check for mechanical and electrical issues first. Should not be a big problem, but I recall my latest displays required a slightly larger cutout. They operated on RM's first generation Seatalk network, which has a curved 3 wire connector, as I recall. It wouldn't be a bad idea to check with RM customer service on compatibility issues. I've found them to be very helpful on a Seatalk compatibility issue for a replacement GPS antenna on a power boat I own. They actually recommended a competitive antenna and told me how to wire it to my older RM chartplotter. That option saved me over $200.
