Calcium deposits
Where yachts remain unused for long periods it is possible for a hard calcium
deposit to form on the propeller shaft.
If
this deposit forms between the joins in the
cutlass bearing, when the shaft revolves for the first tune the hard calcium deposit
can cause damage to the bearing surface. This is normally associated with noise and
vibration from the bearing area. If this happens stop the engine immediately and
investigate. The deposit can be removed with a sharp scraper. To gain access to the
bearing area, uncouple the propeller shaft at the engine and slide it back until the
affected area is exposed.
Stern
glands_____________________________________
The stern glands on all yachts have
PTFE
packing. This type of gland is water
lubricated, but the locking nut should be given a partial turn daily prior to motoring
to prevent the ingress of water.
Bow thrusters___________________________
The Eclipse 43 and 38 have a three bladed propeller sited inside a transverse tube
near the bow. The symmetrical design produces equal thrust whichever way it
rotates and allows for precise
manoevring.
/
It is advisable to keep operation of the bow
thruster
to a minimum as it uses
a high level of battery power.
