PROPULSION SYSTEM
Propulsion of your 43MY is accomplished
by two inboard engines, located within the
engine compartment. Depending on the
option you chose upon purchase from
your Silverton dealer, the engines are
either fueled by gasoline or diesel fuel.
Each engine transmits its power to a
separate transmission, which rotates the
attached propeller shaft and the propeller,
providing forward or reverse movement of
your yacht as selected from the shift
control unit located on the Port side of the
helm. The photo below shows the Throttle
and Shift Control at the Helm.
The transmissions are counter-rotating.
This is defined as when in the forward
shift mode and viewing forward from aft,
the Port transmission rotates the Port
propeller counterclockwise and the Star-
board transmission rotates the Starboard
propeller clockwise.
Access to the engine compartment in your
43MY is provided through the Hatch in the
deck of the Salon area.
The engine starting procedure is as fol-
lows:
✔Open and inspect the engine compart-
ment. Use your sense of smell to detect
the presence of fuel fumes.
✔Turn battery switch ON.
✔Operate the bilge blower motors for at
least five (5) minutes. Check for air flowing
out of the bilge exhaust vent. The location
of the Exhaust Blower Vent is shown in the
Bilge Ventilation System Pages of this
section of the owners manual. If you feel
air flowing from the exhaust vent, the bilge
blower motor is operating properly.
✔Check the bilge water level. If it appears
above normal, turn ON the bilge pump(s)
and remove the water. Determine the
source of the excess water and repair, if
necessary, before starting the engines.
✔Check the bilge for the presence of any
oil. Determine the source of the oil and
repair, if necessary, before starting the
engines.
✔Open both engine seawater intake
valves(location of these valves are shown
on the Mechanical Layout in the Schemat-
ics Section of this Owners manual). The
valves are open when the handles are
parallel to the valve body(See photograph
