Servicing Paddlewheel Insert & Blanking Plug
1. Use the new paddlewheel shaft to push the old shaft out about
6mm (1/4"). With pliers remove the old shaft (see Figure 1).
2. On the insert, remove any aquatic growth using a stiff brush or
putty knife. Clean the surface with mild household detergent. If
fouling is severe, lightly wet sand with fine grade wet/dry paper.
3. Place the new paddlewheel in the cavity with the flat side of the
blade facing the same direction as the arrows on the top of the
insert.

Follow the precautions below for optimal product
performance and to reduce the risk of property damage,
personal injury, and/or death.
WARNING: Always wear safety goggles and a dust
mask when installing.
WARNING: The valve is not a watertight seal! Always
use the insert or long blanking plug secured with the
retaining pin, safety rings, and safety wire for a
watertight seal.
WARNING: The o-rings must be intact and well
lubricated to make a watertight seal.
WARNING: Always attach the safety wire to prevent
the insert or blanking plug from backing out in the
unlikely event that the cap nut fails or is screwed on
incorrectly.
WARNING: When the valve assembly is removed,
always insert the emergency plug with the CAP NUT
and safety wire for a watertight seal.
WARNING: If the paddlewheel insert is caught in the
valve assembly trapping the cap nut, TEMPORARILY
hold the short emergency plug in place with the safety
wire. Then, separate the paddlewheel insert from the
valve assembly. If they cannot be separated and the
sensor must be left unattended, cut the cable [a
minimum of 1m (3') from the insert] to free the cap nut.
Later splice the cable with a watertight junction box.
CAUTION: Never use solvents. Cleaners, fuel,
sealants, paint, and other products may contain strong
solvents, such as acetone, which attack many
plastics, greatly reducing their strength.
IMPORTANT: Please read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
4. Tap the new shaft into place until the ends are flush with the
insert.
5. Replace the two small o-rings on the paddlewheel insert and
lubricate them with the silicone lubricant supplied. O-rings must
be intact and well lubricated to make a watertight seal.
6. Replace the two o-rings on the long blanking plug.
7. Re-install the paddlewheel insert with the arrows on the top
pointing forward toward the bow. Seat it into place with a
twisting motion until the keys fit into the notches. Secure the
insert with the retaining pin and safety rings (see Figure 2).
