Re: [Amel] B&G Sonic Speed sensor and "the barnacle"

Hi Bill,
go to http://www.bandg.com/upload/BandG/Documents/Manuals/sonicinstall.pdf
It is a Manual we have not normally on board. There is a sketch of the sensor and of its neoprene cap.
Tomorrow - today is Sunday- I'll call to a local dealer I know for help.
All the best

Bill this looks like the lens and and cover. Can or will you please confirm that your photo is from the "upper" hull mount sensor and not the keel unit. I think if it is the upper you can access-it from the forward cabin. If it is the keel you most likely have a big job on your hands. We have an SM and getting to the keel unit would be a major pain to the point that I'd consider putting in a new speed and water temp unit in place of the forward sensor. I know it's not Amel but given your current location well we all do what we have to do. In any case we would NOT go to sea w/0 a fix or at least fast expoxie on the hole and deal with later. Good luck.
Regards
Richard Piller
