The port main engine’s forward belt crankshaft pulley is
fitted with coupling to a hydraulic pump that operates the
vessel’s stabilizers. See the “Running Gear” section for more
details.

4J6: Engine Transmissions
Check the Transmission Oil Levels every two Weeks...
...more often if a transmission shifts
erratically, with the dipstick on the starboard side of
each transmission. It is unlikely that any oil will
need to be added. Be sure to check under the
transmission for leaks! Low transmission oil is a
serious matter.
With the engine idling and in neutral,
remove the transmission dipstick. Wipe it
with a towel, reinsert it, and take a
reading. If the level is below the add
mark, stop the engine, add a half-pint or
so of
30-weight
(
not multigrade)
oil
through the plug in the top of the
transmission case, and then start the
engine and measure again.
Do not
overfill, for to do so could cause the seals
to “blow out”.
