STERN GEAR LUBRICATION
23 Stern Bleed Feed
24 Standard Exhaust with Stern Bleed
Beta 10 to Beta 60 - stern bleed kits ordered with
an engine are factory fitted. If a stern bleed kit is
retrospectively being fitted, the heat exchanger end cap
will require drilling and tapping. Please refer to image 23.
IMPORTANT! -
If a 'water feed take off' is required for stern gear
lubrication of the cutlass bearing or if you have an anti-
syphon valve with 'continuous bleed', then the connection
must be taken after the heat exchanger (not before) and
the maximum size should be an
5mm hose.
(Installations that have excessive water 'bleed' will effect
combustion temperatures and exhaust emissions; and
taken to the extreme could either seize the engine and/or
melt the exhaust system).
25 Stern Bleed with Anti-syphon Valve
Beta 75 upwards - need a 'T' piece with an
connection fitted just after the heat exchanger as shown
in the drawing. It is important that this 'feed' is taken
from the engine side of an anti-syphon valve or you can
'hydraulic lock' the engine with catastrophic results.
