transducer's face, to minimize possible turbulence
(see below).
After cutting the fairing block, trial-fit the block to
the hull. It is very important that the flat top surface
of the transducer be parallel to the water.
Thru-hull Mounting
Take the following steps to mount the thru-hull
transducer:
1)
Drill a 1/8" pilot hole from inside the hull to
assure access to tighten the housing nut and
clearance for the transducer cables. If there is
any hull irregularity near the selected mounting
location, it may be desirable to drill from the
outside.
2)
Use a 1" hole saw and drill the hole from the
outside of the hull. Sand or clean the area
around the hole, inside and outside to insure
that the sealing compound will adhere properly
to the hull. Select a marine grade bedding/
caulking compound and use according to the
instructions.
3)
Remove the bronze hex nut from the housing
and cables.
4)
Uncoil the two transducer cables and thread
them through the hole to the inside of the hull.
WARNING
DO NOT apply tension to the transducer
cables as this may sever internal connections.
Apply a 1/8" thick layer of sealant on the upper
flat surface of the bronze housing and fairing
block (if used).
5)
From the outside of the hull, push the cables
and housing into the 1" hole. Twist the housing
