3. CORRECT LOCATION OF PADDLEWHEEL TRANSDUCER
Generally the transducer should be placed as far forward as possible along the waterline length
and close to the centreline.
It is important that the transducer is always in the water, within the whole speed range of
the boat. Please note that the actual waterline length of fast power boats shortens considerably
at high speeds. Therefore the transducer should be placed at 25-35% along the true waterline
from the bow, when at full speed
Example:
English
LOG Svenska
10-5
Sailboats with a fin keel must have the transducer located at least 25 cm but not more than 75 cm
in front of the keel. It should be placed no more than 10 cm off the centreline.
On sailboats with a pronounced “V” in the hull, such as full-keel yachts, it might be favourable to
angle the transducer slightly so that it aims at the bow, rather than directly parallel to the
centreline.
This will help balanced the passing waterflow measurement from one tack to another.
Avoid placing the transducer near the edge of sharp hull chines. Transverse waterflow in these
areas can affect the accuracy of measurements.
If you have a questions about the location of the through-hull, contact your builder, yacht
dealer, or other owners of similar boats for advice. Always remember to allow for
accessibility from the inside of the yacht when determining the final location.

4. INSTALLING THE THROUGH HULL FITTING
1. Use a 43 mm (1 11/16”) hole cutter to cut through the hull. (See section 3 for correct
location).
2. Apply the polyurethane sealing compound on the outer flange of the through-hull fitting and
tighten the nut on the inside by hand.
3. Slide both rubber O-rings on the dummy plug.
4. Generously apply the silicone grease to the exterior of the dummy plug.
5. Install the dummy plug in the through-hull fitting. Use a slow twisting motion and be sure that
is properly seated into the fitting.
6. With the dummy plug properly installed in the through –hull fitting, mount the fitting so that
the handle is exactly at right angles (90º) to the boats centreline. (For pronounced V-hulls
see section 3).
7. When this outer sealant has cured, remove the nut and apply sealant on the inside. Tighten
the nut again by hand.
8. Install the wire locking device onto the dummy plug /paddlewheel transducer.

5. CONNECTION TO INSTRUMENT/CONTACTS
The log/temp transducer connects to the Nexus Server or directly to the Nexus Speed Log.
The transducer cable is clearly marked with No 1 and the colours will correspond to input screw
terminal on the Server.
If the 8 m transducer cable needs to be cut, use the extra cable protectors supplied. Press the
protectors on to each wire with a pair of flat pliers.
6. CALIBRATION
Calibration is carried out in the Multi Control instrument or the speed log instrument (see manual).
