Inspecting the transducer
While the vessel is still in dry dock, the transducer surface must be inspected for potential damage that may have been inflicted during the installation.
Prerequisites
Neither tools nor instruments are required.
Context
Image
A Lower part of transducer shaft
B Transducer with its red protective coating
The transducer is covered with a thick red protective coating made of a special plastic type. The red protective coating is an vital part of the transducer. It is very important that neither this coating nor the internal parts of the transducer are damaged during the handling, installation or cleaning. Any holes and/or scratches in the transducer surface will allow water to penetrate the transducer. If a leak occurs, the transducer must be replaced.
Procedure
1 Lower the transducer using the hand crank.
a Locate the hand crank inside the Motor Control Unit.
b Remove the hand crank from its storage position.
c Remove the plastic plug on the top cover of the hull unit.
d Mount the hand crank onto the stub shaft through the hole in the top cover.
e Use the hand crank to lower the transducer.
2 Do a thorough visual inspection of the transducer.
Check for dents, scratches, holes or other damage to the surface.
Note
It is very important that neither this coating nor the internal parts of the transducer are damaged during the handling, installation or cleaning. Any holes and/or scratches in the transducer surface will allow water to penetrate the transducer. If a leak occurs, the transducer must be replaced.
3 If you suspect damage, take a high resolution photo.
4 Contact your dealer or the Simrad support organization for advice.
5 Use the hand crank to hoist the transducer.
a Turn the crank until the transducer is fully retracted.
b Remove the hand crank from the stub shaft, and mount it in its storage position in the Motor Control Unit.
