Westerbeke 20B TWO/30B THREE User Manual

Shifting
To
shift the transmission from NEUTRAL into FORWARD, exert a heavy push to the remote control lever. A
gentle throw may
not carry enough force to actually shift the transmission's internal gears. A genUe throw is
signalled by the transmission not engaging into the desired drive.
Make sure the remote control lever is lubri-
cated at lease once each operating season. Shift the transmission whOe the engine is running at 1200 rpm
or
below.
CAUTION
NEVER remove or loosen the two-bolt gear box lever cover from transmission. The position
of this plate
and the actuating lever inside of the transmission has been finely adjusted at the
factory to ensure equal throw distance of internal mechanisms. Loosening of this cover's
capscrews voids the transmission's warranty.
Sailing Operation
JIle JS transmission should· be left in its NEUTRAL position whOe saDing. Leaving the transmission in
NEUTRAL whOe saDing alleviates unnecessary drag on the vessel because the propeller is able to freewheel
(spin).
However, it the transmission is left in its FORWARD gear whOe saDing, the transmission will not be
damaged. (Leaving the transmission in NEUTRAL is just good saOing practice.)
Service
) If any seal on the transmission shows signs of leaking, have the transmission looked at by a qll!llified Wester-
beke Dealer. This problem, especially conceming the rear seal, is often contributed to an improper align-
ment of
the transmission's coupling and the propeller shaft's coupling. . .
Never loosen the gear box lever cover screws, except in the course of qualified servicing; this upsets criti-
cal adjustments.
Disassembly of the transmission in the field is not recommended. If an overhaul or repair is needed, the
WOI1< shc:iuId be done by Westerbeke or an authorized Westerbeke service center.
Cooling
The JS transmission is sea water-cooled. Sea 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.
