I was down at the marina to fix up some items on a customer's 5 year old, 45' cruiser yesterday. One of the items was related to the GPS/Chartplotter/radar display not working properly. The first thing to check is the connections on the back of the flush mounted display. So. how do I get to them? There's no access to the back side of the instrument panel from the head compartment. The whole panel is one piece that would be a huge endeavour to undo if it could be done at all. Maybe if I remove the switch panel closest to the plotter I can somehow reach in and get at the fasteners on the back side. I could just get to the nearest corner of it but there were no fasteners to be found. Then I found it. There were no fasteners. They glued the electronics into the panel with silicone! How in heck is someone supposed to get at them for service or repair without causing damage to the electronics or the fiberglass panel. This is not the first time that I have run across this dilema. I one other instance they used black Sikaflex to mount all of the electronics and instrumentation. Unfortuneatly, we did some expensive damage trying to get them out of the panel. So, a plea to the boat manufacturers out there. Please design the helms with access for service. And to the riggers, don't glue the stuff in. Thanks.
