Installation-Wet Box Mount

The second best type of mounting (where practical) is the "Wet Box"
method. With this type of mount, it is an absolute requirement that
the hull is solid, and not a double hull or cored hull design. Use a
piece of PVC pipe or similar material to create a small chamber.
Epoxy the pipe in place against the hull, being sure that the epoxy is
applied all around the pipe so that it will hold liquid. Make a lid to
fit the top of the chamber and mount the transducer to the lid. Fill
the chamber with mineral oil which won't evaporate or causecorro-
sion as water would. In operation, the signal is transmitted through
the mineral oil and through the hull. (The viscosity of the mineral oil
will not affect the accuracy of the display.) The primary advantages
of this type of mount is that there is no hole through the hull to
compromise it's integrity, and the transducer is protected from the
growth of marine life.
If using this type of mount on a tri-hull or cathedral hull, make sure
that you don't mount the transducer over an air slot.
On planing hulls, make sure that the transducer is mounted over an
area that is always submerged.
A transom mount transducer may also be used.
If you use this type of mounting with your MC 800, you will have to
add an external temperature sensor to obtain water temperatures.
