I would not give a quote out for that
installation unless I had installed the
VHF and
autopilot myself. There are way too many variables. I don't know what I'm going to find when I get on your
boat. I just spent the morning easy-outing floor board screws that an owner put in himself. I'm a technician not a professional gambler. Yet you want someone to gamble with their time on a piece of
equipment that someones life could depend on. As a professional I can't just use that previously run speaker wire that is twisted under a
battery wingnut, for a
power source. So If I were forced to make a quote for the job I would take the 5 hours it's probably going to take and double it to ten. The good news is at ten hours your installer probably knows what he's in for.
That doesn't mean you're not capable of doing it yourself, but if you're going to try to connect to a 6002
autopilot controller instead of the course computer you might be getting in over your
head.
The last time I connected an older not supported autopilot to a newer lighthouse display with sea talk, there was some trouble. It worked but the newer display kept popping up little annoying boxes offering to do things with the autopilot it couldn't do. Your best to just give the pilot a 0183 input to steer to and leave it at that. Ray may tell you to us a
seatalk to
seatalk NG converter box like I did but you probably won't be happy.
