J S AND B W TRANSMISSION
SAILING OPERATION
It is recommended the transmission be left in NEUTRAL
position while sailing. Leaving the transmission in
NEUTRAL while sailing alleviates unnecessary drag on the
vessel because the propeller is able to freewheel (spin).
However, to stop the propeller shaft from rotating while
under sail, place the transmission in REVERSE.
COOLING
The transmission is raw water-cooled. Raw water enters the
transmission through a stainless steel inlet pipe located at the
base of the bell housing. This water helps to cool the
transmission's lubricating oil.

BELL HOUSING
SERVICE
If
any seal on the transmission shows signs of leaking, have
the transmission looked at by a qualified WESTERBEKE
dealer. This problem, especially concerning the rear seal, is
often contributed to an improper alignment of the
transmission's coupling and the propeller shaft's coupling.
Disassembly of the transmission in the field is not
recommended.
If
an overhaul or repair is needed, the work
should be done by an authorized WESTERBEKE service
center.
MAINTENANCE
Transmission maintenance is minimal. Keep the exterior
housing clean, check the fluid level as part of your regular
routine, and change the fluid every 300 operating hours.
Periodically inspect the transmission and the cooler for leaks
and corrosion. Make certain the air vent is clear and when
checking the fluid level look for signs of water contamination
(fluid will appear as strawberry cream).
Lay-up/Winterize
Storage requires special care. Follow
the~
procedures:
NOTE: This operation will usually occur when the engine raw
water water cooling system is properly winterized.

Clean up the transmission and touch-up any unpainted
areas (use heat. resistant paint).

D
Fill the transmission with SAE 30 engine oil to prevent
internal corrosion. (Extended storage only, 12 months or
more).
D
Loosen attaching hardware from the transmission output
flange and propeller shaft coupling flange before
removing the boat from the water. Seperate the flanges
and spray with lubricant.
D
Inspect the gear shift cable, linkage, and attachments.
Look for corrosion of the end fittings, cracks or cuts in
the conduit, and bending of th~ actuator rods. Lubricate
all moving parts.
NOTE:
If
the transmission is to be stored for a long time
(twelve months or more), it should be topped off with oil to
prevent internal corrosion. Reduce the oil level before putting
the engine back into service.
