Fitting The Anti-Rotation Bolt; Fitting The Transducer - Raymarine RV-300 Series Installation Instructions Manual

Fitting the anti-rotation bolt

1. Wipe the anti-rotation bolt with an appropriate cloth and cleaning agent
(for example: isopropyl alcohol), and ensure the surfaces are dry, clean
and free from debris.
2. Apply a thick bead of marine-grade sealant around the stem of the
anti-rotation bolt, near the head of the bolt.
3. Guide the anti-rotation bolt through the hole in the transducer ensuring
that the bolt head is properly seated.
The anti-rotation bolt hole includes a captive nut cutout to prevent the
bolt from turning during tightening.
4. Apply a small amount of marine grade sealant to the inside of the
anti-rotation bolt cap.
5. Fit the anti-rotation bolt cap by pressing it firmly into the hole in the
transducer.
The embossed "BOW" arrow must be pointing towards the temperature
sensor in the base of the transducer.

Fitting the transducer

Follow the steps below to fit the transducer to your hull.
Note:
Ensure that a generous amount of marine-grade sealant is used on all
mating parts and that the parts are clean and dry before installation to
ensure a long lasting watertight seal is achieved.
Mounting and sealant application
1. Carefully remove all labels from the top face of the transducer.
2. Remove the labels from the top face of the transducer including any
residual label glue.
3. Using an appropriate cloth and cleaning agent (for example: isopropyl
alcohol), wipe clean ALL surfaces of the supplied components and the
mounting location, both outside and inside the hull ensuring that they
are free from grease, debris.
4. Apply a thick bead of marine-grade sealant:
i. all over the top face of the transducer so that it is completely covered.
ii. all around the bottom part of the threaded section of the transducer
stem and the protruding anti-rotation bolt, ensuring that the sealant
will protrude approximately 6 mm above the final tightened nuts.
