I have a 2000 H340 with the full complement of factory installed monitors, sensors and instruments. Looking back over the past few years, I have noted that these instruments are aging and have begun to fail. This is solely based on my experience but there seems to be a trend nonetheless.
Three years ago I noted that the twelve year old diesel fuel level sender started to falter and finally failed so I replaced it. The following year the thirteen year old WEMA water tank level indicator failed and had to be replaced. That same year I had to replace my masthead Windex and the Raymarine masthead ST60 wind instrument both of which blew off during hurricane Sandy but I expect that after spinning away, summer and winter for those many years they would have been on my replacement schedule sooner or later. That same year I had to replace the circuit control board in my Cruise Air reverse cycle air conditioning unit. Last year, my fourteen year old paddlewheel speed transducer gave up and was replaced. I also had to replace my original VHF radio but gained many new features in the newer model. This year, my fifteen year old WEMA holding tank level sensor stopped responding. I have read the posts about how to remove and clean the device but truthfully, I thought that would be more trouble than it was worth and in light of its age and of the unavoidable yuck factor; I just bought a new sensor from the HOW site and easily installed it. Not unexpectedly, my Raymarine depth sounder is starting to give me occasional erratic reading when at anchor which were improved but not entirely eliminated by cleaning the contacts on the back of the display unit. Thus far, the oil pressure and water temperature sensors on my trusty Yanmar 3GM30F have held up. We all get old.
