Although I have seen Raymarine equipment corroded, the problem is
always poor installation. The other brands are just as likely to come
in encrusted with salt, etc. The guys who insist on mounting the all
around light in the lid of a radome are just setting themselves up
for water damage later on. A cheap test instrument for radar
transmission is one of those under $ 10 microwave oven leakage meters.
Of course, the old neon bulb on a wooden dowel still works also.

Naw....Just sit a Raymarine out in a humid environment with its little
rubber drain tube breathing in and out as the sun rises and sets and it
soon fills with condensate water, destroying the pot metal the cheap POS is
made from.

This new unit we got has 4 white plastic "feet" to hold the radome up off
the mounting plate. There's no sealing it, now, but that didn't make any
difference anyways. The mounting bolts go through the hole in the center
of the plastic feet which space the dome about 1/2" off the mount, now. I
don't see that's going to solve the condensate problem, though. It rains
inside the dome through the drain tube, just like a half-empty gas tank
gets condensate water in it, left that way in the sun.

It's NOT a Raytheon, any more.
