For Through-Hull Installation - VDO Ocean Line 08 601 101 Instrucciones De Montaje

Installation of the echo sounder: through-hull installation
Make a hole, 53 mm diameter, at the selected location. The hull thick-
ness should not exceed 36 mm.
Camber the hole out at 45 degrees for good sealant distribution and to
obtain a reliable seal. Install the hull sleeve and the echo sounder as fol-
lows:
Hull sleeve installation:
1. Put salt-water resistant sealant on the hull sleeve flange and insert
the hull sleeve from the outside into the hole.
2. From the inside, install the black sealing ring on the hull sleeve,
then the white one, and screw the fixation nut down.
Lightly hand-tighten the fixation nut first. After letting the sealant
harden, tighten the nut by hand and check the hull feedthrough for
leaks.
