Clean the insert with a Scotch-Brite® scour pad and mild
household detergent, being careful to avoid scratching the
depth transducer. If fouling is severe, remove the padd-
lewheel. Lightly wet sand it with fine grade wet/dry paper.
The water lubricated paddlewheel bearings have a life of up
to 5 years on low-speed boats [less than 10 kn (11 MPH)] and
1 year on high-speed vessels. Paddlewheels can fracture and
shafts can bend due to impact with water borne objects and
mishandling in boat yards. O-rings must be free of abrasions
and cuts to ensure a watertight seal.
1.
Remove the old paddlewheel shaft with needle-nose
pliers (see Fig. 5).
2.
Place the new paddlewheel in the cavity with the
flat side of the blade facing the same direction as the arrow
on the top of the insert.
3.
Tap the new shaft into place until the end is flush with
the outside wall of the insert.
4.
Install a large O-ring near the top of the insert. Install a
small O-ring near the paddlewheel.
5.
Place the remaining two O-rings near the bottom of the
blanking plug.

2.
Remove the insert from the housing by removing
the safety wire and unscrewing the cap nut (see Fig. 3). This
will jack out the insert.
3.
With the blanking plug ready in one hand, pull the
insert most of the way out. Remove the insert and rapidly re-
place it with the blanking plug. With practice, only 250 ml (10
oz.) of water will enter the boat.
WARNING! Be sure the blanking plug is fully inser-
ted into the housing, and the cap nut is screwed on
completely.
4.
Screw the cap nut several turns until the threads are
engaged. Continue to tighten the cap nut. Hand-tighten only.
Do not over tighten.
WARNING! Always attach the safety wire to prevent
the insert from backing out in the unlikely event that
the cap nut fails or is screwed on incorrectly.
5.
Reattach the safety wire.
