It should be relativley easy to build a plexiglass box it could fit
into, with a watertight sealable front panel you could open to get to
the controls if needed. Then mount the whole thing on an arm. This
would both protect the screen from water and something hitting it.


why **** around with building plastic boxes?

Because its inexpensive to build yourself, durable, and you can
customize it to fit your own boat not a generic one that is suppose to
fit all and doesn't. Why search trying to find something that you will
only have to pay manufacturing costs on when you can get everything you
need at a hardware store. How do you think ideas get started.

You tell him for me that if that damned "swing arm" has a knob that turns
to lock it in place that will swing free when the knob is loose for him to
save his money. Geoffrey paid a fortune for this fancy aluminum dual arm
thing from Waste Marine and it's USELESS AT SEA! Any roll or pitch that
can loosen that damned screwlock does so and BANG!...there goes whatever
is
bolted to it into whatever it can bang it into....

USELESS....

$174 and it doesn't even have a lock washer! If anything turns
counterclockwise from a roll...it has NO LOCK AT ALL and swings totally
free! How awful...looks nice, though....USELESS!!


My friend will probably build his own as he hates to pay for anything he
*thinks* he can build.
I put my JRC radar display on a couple of RAM mounts which are swing arms
that are probably similar to what you have. I find you can't really get
them to stay in place by just trying to turn the large knob.
What seems to work is to hold the knob and work the arm back and forth. You
can get things really tight that way. My radar stays in place but not yet
tested in rough water.

Why a box? You picked a design with about 12 seams that need to be
sealed and requiring a complicated contour matching and assembly process.

Use a cylinder of Plexiglas, fibreglas, or maybe even ABS, PVC, or one
of the other dirt cheap, commonly available, construction materials.

Lots of room for ingenuity here. Use a end piece that will take a cap
or plug. Cut it to an approximate fit and then lay a piece of coarse
abrasive on the mounting spot and sand it to fit. Then fibreglas it
into place.

I remember some housings that were around in the early 80's that were
filled with mineral oil instead of water to get a better acoustic
transfer.
