POWER CURVE (A) BSAU 141a ( 1971 ) is an u~t~ate and meanin gfu l
engine rati ng system used In response to en'lironmental requirements and
the desi
re to be factual. Engin es are rated lor maximum h()(sepower and
rpm with all necessary auxiliaries wOrking. They must comply with modern
st andards 01noise leyel, exhaust emissions and luel consumption. Curve
(B) shows the power available lor intermittent use. Curve (C) shows the
power
ava ilable lor continuous use. Curve (0) is Ihe propeller law curve.
STANDARD EQUIPMENT
Fresh water cooling system with surge tank and pump
mounted on engine ; raw water pump and heat exchanger
mo unted on engine ; 12 volt, 55 amp alternator with transistor
regulator; adjustable flexible mounts ; propeller shaft
coupling ; hydraulic reverse gear; full flow lube all filter with
spin-on element; secondary fuel filter ; fuel pump hand
pr i mer ; flexible hoses for fuel inlet and return ; sumo pump
and hose; threaded exhaust flange; instruction manual ,
engine alarm
system .
OPTIONAL EQUIPMENT
All electric i nstrument panel with tachometer , hour meter ,
voltmeter , water temperature and oil pressure gages; engine
pre-wiring ;
high capacity pr i mary fuel filter; extra120 amp al-
ternator ; flex i ble shaft coupling ; keel cooling ; extra crank-

PERFORMER ECONOMICS
The design of the Westerbeke PERFORMER-SIX follows an
earlier
model with years of dependable performance . It has
been redesigned and updated to conform to the most modern
env ir onmental, power , and service standards . In redesigning ,
ma jor improvements were made in valve si ze , combus t ion
chamber and i njectors, resulting in better breathing, smooth-
er combustion, better efficiency and fuel economy, clean
exhaust and improved cold starting . Unusual care was given
to
simplifying service, and extending the periods between
ma La r overhauls.
The
block of the PERFORMER-SIX lends itself nicely to
marine use. Its clean lines permit plac ement of piping and
accessories most logically , where they are out of the bilge
and handy for service, and where they do not interfere with
work on ot her parts of the engine . Th is makes the PER-
FORM
ER -SIX easy and inexpensive to service. Eas ily replace-
able
internal parts reduce the cos t of maj or overhauls.
Longer intervals between rout ine serv ic e and between major
overhauls means lo wer service costs and more lime on the
job . Its dependability , durability , safety , and resale value are
factors , which when translated into dollars and cents make
the PERFORM
ER -SIX an economical engine for any boat,
commercial or pleasure.

PERFORMER ECONOMICS
The design of the Westerbeke PERFORMER- SI X fo llow s an
earlier model with years of dependable performance. It has
been redesigned and updated
to conform to the most modern
enviro
nmenta l, power, a nd service standards. In redesigning,
ma
jor improvements were made in valve size, co mbust io n
chamber and
injectors , resulting in better breathing, sm oo th-
er
combustion , better effic iency and fuel economy . clean
exhaust and improved cold
starti ng. Unusual care was given
to s
impl ifyi ng se rv ice, and extending the periods between
ma
Lo r overhauls.
Th e block of the PERFORMER-SIX lends itself nicely to
marine use. Its clean lines permit placement of piping and
accessories
most logically, where they are ou t of the bilge
and handy
for service, and where they do not interfere with
work on other parts of the engine. Th is makes the PER -
FORMER-SIX easy and inexpensive to service.
Ea sily replace-
able internal parts reduce the
cos t of major overhauls.
Longer intervals between routine service and between major
overhau ls means lower service costs and more time on the
job . Its dependabilit y, durability , safety, and resale value are
fac
tor s, which when translated into do lla rs and cen ts make
the PERFORMER-SIX
an economical engine for any boat,
commercial or pleasure.
