Pick any measure you like, miles, years or hours of use. There's no sailboat system in any size boat that has that kind of reliability, even brand new.
I would have to respectfully disagree with you on "There's no sailboat system in any size boat that has that kind of reliability". I believe my cable steering system has many times the 1600 hours on it and the autopilot has at least that. The Raymarine wind speed and angle system certainly has many, many times 1600 hours on it (21,000+), as it's on 24/7/365. Of these three systems, two do not even need periodic maintenance.
There are probably other systems that have at least 1600 hours on them without failures, like the fresh water pump, refer and a/c seawater pumps (magnetic drive) and even the sump pump, but I can't really count hours on them. I have run the Little Giant seawater circulation pumps on a/c units for 3 years, when I lived dockside in Fla and SC without problems 24/7/300 or so days a year, without any maintenance at all.
Considering that all our boat equipment operates in the salt water environment it does, it is actually amazing how long some systems do function without problems.
