TRANSDUCER INSTALLATION MANUAL TRANSDUCER INSTALLATION MANUAL
6 WASSP WIDEBAND FAIRING TRANSDUCER 90-190KHZ
INSTALLATION
Follow the following guidelines:
»
DO NOT use the WASSP Wideband Fairing Transducer 90-190kHz for boats
exceeding 40kn. Instead, use the WASSP 160kHz Transducer.
»
A WASSP gland must be used to lead the WASSP transducer cable through the hull.
»
Mount the front of the transducer facing forward. (the transducer can be mounted
back to front if necessary. Enable the setting swap array in the corrections page of
the WASSP web pages)
»
The fairing can be cut up to a 30 degrees deadrise.
»
The Locking nuts must not exceed 30N-m torque when tightening the nuts.
»
Ensure the threaded rods are isolated from the hull when installing on an aluminium
hull to prevent electrolysis.
»
A coffer dam must be installed to ensure hull integrity is maintained in the event of
forces in excess of 40kn water pressure (such as a collision).
»
Consider a cofferdam to ensure the structure of the hull in case of unexpected
events like collision.
6.1. MEASURE AND PREPARATION
1. Measure the deadrise of the hull at the
transducer mounting location.
2. Cut the fairing using the measured deadrise
angle. The cutting guide on the fairing can be
used to guide the fairing over a bandsaw table.
3. Hold the fairing against the outside of the hull
to make sure there is no spacing between the
fairing and the hull. Gaps could result in bending
and cracking the fairing.
4. Hold the backing block against inside of the hull
to make sure there is no spacing between the
backing block and the hull.
30° max.

NOTE: AFTER THE FAIRING IS CUT, THE
SECTION WITH THE CUTTING GUIDE
BECOMES THE BACKING BLOCK
5. Mark the locations for the 2 threaded rods while holding the fairing or the backing
block.
6. Mark the cavity for cable gland area.
7. In the cavity for cable gland area mark the position for the gland. Make sure to
allow at least 4cm distance between the centre of the WASSP gland and the
outside of the gland cavity area.
Consider the space available in the cavity for cable gland area of the backing block when
using the WASSP Wideband Fairing Transducer 90-190kHz with fairing. Additional space
can be created by creating a gland relief cut-out in the backing block for additional space
to fit the gland or a relief for a suit bulk heads.
