IX. KEEL/KEEL WINCH
The MATILDA drop-keel works on a four-pulley system. The bearings on
these pulleys must be greased as frequently as needed. Two to three
checks a year should prevent them from freezing up. Grease the pulleys
early Spring, mid Summer, and late Fall if needed. To get at the
pulleys:
1. Unscrew top panel of keel housing on starboard side.
2. Grease with "wheel bearing grease" available at most automotive
supply stores.
At the bottom of the aft section of the keel housing, there is a
stainless lock-pin bolt that prevents the keel from going down further
beyond this point. Do not remove this bolt. If you must, do so only
when boat is out of the water. Caulk with heavy marine sealant when
you rebolt this fitting!
When using the keel winch, the winch pawl lock works automatically
when raising the keel (clockwise direction). When lowering the keel,
the winch pawl lock must be released BEFORE going in the anticlockwise
direction. Once a desired position is reached, the lock pin must be
set back on the ratchet before taking your hand off the winch handle.
FAILURE TO LOCK WINCH PAWL LOCK OR MAINTAIN PROPER CONTROL OF WINCH
CAN LEAD TO SEVERE DAMAGE TO THE BOAT AND POSSIBLE INJURY TO THE
OPERATOR.
It is advisable to remove winch handle and store below deck especially
when boat is left unattended at mooring.
The keel must be let to rest on trailer when trailering and should be
raised as far up as possible when launching or recovering at ramp.
