ENGINE LOCATION AND LOCATION Many boat manufacturers are now providing preformed
fiberglass mounting beds for their engine These
The overall layout of the engine room should be planned for beds when used should be of sufficient thickness for proper
easy inspection servicing and handling of the engine support and should be wellglassed to the hull when study all the equipment to be
installed and make
a paper plan to provide optimum engine room space Avoid the temptation to install the engine on a pair of the following
irons glassed in place Such a construction will allow
1 Ventilation Since an increase in engine room vibration to pass through to the hull Flexible engine
temperature causes a reduction in the intake air and thus a mounts require a firm foundation
drop in engine output ventilation inside the engine room
must be ample See your Operators Manual for the
ventilation requirements for your a Dimension and capacity with a ventilator installed
b Dimension and capacity with an intake duct
2 Engine Room Height For engines having a top oil fill
the distance from the oil cap at the top of the rocker cover
to the overhead must be enough that oil can easily be
3 Space to move the propeller shaft flange Allow
approximately 3 4 in 77 100 cm of space to move
the flange toward the stern for changing the etc
4 Exhaust System Make sure there is adequate space for
all exhaust system components including the exhaust
silencer See the BASIC EXHAUST SYSTEMS section in
this BED
A strong mounting bed contributes to the and operating of the engine The bed must be
rigidly constructed and neither deflect nor twist when it is
subjected to the engines weight or to the pressures that the
boat may experience while operating in rough seas The bed
must be strong enough to keep the engines alignment within
one or two thousands of an inch at all times The bed has to
withstand the forward push of the propeller shaft It is also
critical that the beds are parallel to one another and to the
line of the propeller shaft when viewed from above They
also must be offset an equal distance from the line of the
propeller shaft
In fiberglass hulls we recommend that solid wooden similar to those in wooden hulls be formed and
fitted then glassed securely to the hull This will allow the
hanger bolts to be installed firmly in the wood noise and transmitted vibration When preparing the engine load also plan
out and build an
engine drip pan To simplify cleaning up after oil changes
The stringers must be as wide or wider than the engine
consider a separate drip pan for use under the oil and fuel
mounting isolator Avoid excessive height Isolator overhang
rounded stringer surfaces are detrimental to the
flexible mounts ability to retain between the bed stringers and supports extending at SSB angles from the stringers to the hull may be
required for If your boat needs a ground plane for a radio and other
proper strength and to aid in the absorption of vibrations electronic gear this is the ideal time to bond a engine bed must be constructed
so that a wrench can be area of copper mesh into the base of the engine space while
set at the engine base to retighten the engine mounting bolts it is the mounting feet
ENGINE LOCATION AND MOUNTING The engines mounting angle cannot exceed 15L from the
horizontal plane Refer to the specification section in your
Bronze or stainless steel hanger bolts of appropriate size are
operating manual for the angle limit of your for use through the engines flexible mounts
Less preferred are lag screws because their hold on the wood NOTE There are various transmissions that provide down
is weakened every time they are moved whereas hanger angle output flanges to help in positioning the engine on a
bolts stay in position If the nut on top of the hanger bolt is more level to allow the engine to be lifted the hanger bolt
itself remains in place as a stud Consequently the bond
between the hanger bolt and the wood is not weakened by
the removal of the nut or the engine
To screw a hanger bolt onto a stringer thread two nuts onto
the hanger bolt jam them together then turn the hanger bolt
into the stringer using a wrench on the uppermost nut
A solid level mounting platform is very important for the Generator mounting rails have numerous predrilled bolt
proper operation of your generator Select a location that will holes to ensure that the generator is properly positioned and
allow adequate space on all sides for ventilation and secured to its mounting preferably on and parallel with the keel or vessel
center line Keep the generator away from living quarters
and away from bilge splash and vapors
Make sure there is room to access the following Negative and positive battery connections
Fuel inlet and outlet connections
Oil fill and oil drain hose
Raw water inlet and outlet
Location of the owner supplied fuelwater fuel filter
A generator will rock on its mounts in rough seas is necessary on all sides Larger generators require
up to a threeinch 76mm supporting the generator from bulkheads which can
create drumming effects and transmit noise and the location is preferable in the same room as the propulsion engine as this is usually a
well ventilated area insulated close to the fuel supply and
the center of the electrical load distribution However a
generator cannot be installed in the propulsion unless specific conditions are met
USCG regulation 33CFR183 pertains to gasoline fuel
systems and requires a generator operating in a gasoline to be ignition protected This means a
generator capable of operating in an explosive igniting that environment Properly installed and
operated a WESTERBEKE gasoline generator can operate
in an explosive WARNING Gasoline fire or explosion can result in
severe personal injury or death Do not install a
gasoline generator in the same room or compartment as
a diesel engine or generator The diesel unit may not be
ignition protected and may ignite gasoline fumes Be
sure a gasoline generator is installed in its own room or
compartment on a diesel powered boat
Do not install a diesel generator in the same room or
compartment as a gasoline engine
SOUND are custom designed sound enclosures for each model
of WESTERBEKE generators The Sound Guard is a easy to clean enclosure that reduces the to a pleasant hum The enclosure can be in close action
fittings allow for easy access for inspection or
routine maintenance of the generator If major repairs are
needed all the panels can be disassembled in a few minutes
No tools Guard is prepackaged with the skirt and to assure a safe arrival and easy provides the necessary fittings hoses for water exhaust fuel

care should be taken to avoid damage to any exposed parts
Be careful not to allow dirt to enter any openings created by
the removal of equipment Reinstall the components in positions after the engine is in its installation area
Replace gaskets as needed for the parts that were removed
A propeller shaft halfcoupling is available for all It is bored to shaft size for the specific order and has
either a keyway with set screws and two locking bolts or is
of the clamping type with a keyway
This coupling is carefully machined to allow a onto the shaft and to make an accurate between the coupling and the output flange of forward end of
the propeller shaft has a long Any burrs should be removed from the shafts end
The coupling should be a light drive fit onto the shaft and
the shaft should not have to be scraped down or filed in order
to get a fit It is important that the key be properly fitted to
both the shaft and to the coupling The key should fit the side
of the keyway closely but should not touch the top of the
keyway in the hub of the coupling
If driving the coupling over the shaft is difficult the coupling
can be expanded by heating it in a pail of boiling water The
face of the propeller coupling must be exactly the center line axis of the propeller shaft Have a
machine shop fit the coupling and face the coupling so that
the mating surface of the flange is at a perfect right angle to
the propeller shaft
After driving the coupling over the shaft remove the two
locking bolts from the coupling and countersink the shaft
below each locking bolt hole Insert and tighten the two
bolts then wire the two bolt heads together with This will secure the coupling to the shaft security a stainless hose clamp can be the coupling
shoulder and over the two bolt heads

PROPELLER SHAFT engine must be exactly aligned with the propeller shaft
No matter what material is used to build a boat the material
will be flexible to some extent The boats hull will change
its shape to a greater extent than is usually realized when the
boat is launched and operated in the water Therefore it
becomes extremely important to check the at frequent intervals and to correct any errors
when they between the engine and the propeller shaft The alignment is correct when the propeller shaft can be
often creates serious problems which are often blamed on easily slipped backward and forward into the areas suspected of causing the
trouble Misalignment and when a feeler gauge indicates that the flanges come
will cause excessive bearing wear rapid shaft wear and will together at all points The alignment between the propeller
in many cases reduce the life of the boats hull by loosening shaft halfcoupling and the transmisson halfcoupling can
the hulls fastenings A bent propeller shaft will produce these contain an error no greater than 001in 25 mm per inch of
same effects therefore a perfectly straight propeller shaft is the coupling diameter For example if your propeller necessary One result of
misalignment may be halfcoupling is 3 76mm in diameter the maximum error
leakage of transmission oil through the rear oil that can be allowed in the alignment is 003 in If oil should leak from this seal check and
make sure
that the alignment is within the limits attempt a final alignment when the boat is on land
The boat should be in the water and have had an assume its final water form The propeller coupling alignment is best performed with the
fuel and water tanks about half full with all the on board and on sailboats after the mainmast
has been stepped and the final rigging has been sufficient time to make this alignment dont be
satisfied with less than perfect results
In making the final check for alignment the transmisson
halfcoupling should be held in one position and the align
ment with the propeller shaft halfcoupling tested with the
propeller shaft halfcoupling in each of four positions A
while rotated 90 between each position This test will also
check whether the propeller shaft halfcoupling is in exact
alignment on its shaft Then keeping the propeller shaft
halfcoupling in one position the alignment should be
checked by rotating the transmission halfcoupling in 90L
increments checking dimension A while in each 90L
position until it has been rotated fullcircle
The engines alignment should be rechecked after the boat
has been in service for one to three weeks and if necessary
the alignment performed again Usually it will be found that
the engine is no longer in alignment This does not mean that
the first alignment has been done improperly rather it means
that the boat has taken some time to take its final shape and
that the engines bed and stringers have probably absorbed
some moisture It may even be necessary to realign the
coupling halves again at a later time
The type and size of propeller varies with the gear ratio and
must be selected to fit the application based upon boat tests
To utilize the full power of the engine and to achieve ideal
loading conditions use a propeller which will permit the
engine to reach its full rated rpm at full throttle while under a
normal load and while the boat is moving forward through
the water
The following information is needed to calculate and match a
marine propeller to a boat
a The engine output in hp
b The maximum rpm of the engine
c The reduction of the d The maximum hull speed of the boat
e The type of boat and its f The waterline length LWL
Most propeller shops now have computer programs that will
analyze all this data and select the propeller choices in
number of blades diameter and pitch Inwater is always the final answer

EXHAUST SYSTEM GUIDELINES Sea Water Intrusion Through The Exhaust Outlet
These guidelines dated February 2004 supercede all The diagram above illustrates a below waterline guidelines published by

is to prevent sea water intrusion into the engine at the exhaust We need to define the water line for exhaust under all conceivable conditions of
boat trim boat purposes By water line we mean the highest point the sea conditions and heel angle while not exceeding level can

The higher the better Maximize this height C because it is
your only defense against a passing wave rogue verticality D of the hose run from the high point to the
exhaust outlet is also important When a momentarily rising
water level immerses the exhaust outlet and is water velocity towards that through hull fitting it is easier
for the intruding water to rise along a sloping hose towards

the sea water Boat operators may be accustomed to seeing a seacock This can occur when any part of the sea engine exhaust
outlet dip beneath the water frequently when
water system or exhaust system are below the worst case underway and think this is acceptable for a generator exhaust
water level other than the seacock itself which is already outlet as well Not so When the boat is underway exhaust
below the water level of course What happens is that upon pressure keeps water out of the propulsion engine shutdown sea water siphons from
the intake seacock But when the generator is not running there is no exhaust
up through the sea water cooling circuit containing the sea pressure to keep water out of its exhaust outlet The exhaust
water pump heat exchanger and water injected exhaust outlet of engines which may not be operating when the

past the impeller of the sea water pump and fill the muffler be well above the worst case water level
and all hoses attached to the muffler until the outside water
level is reached If the engine exhaust manifold is below the Cumulative water level seawater will simply pour into the Water
intrusion between operations of the engine is a
cylinders destroying the engine cumulative process If just a little bit of water spills over the
high point but it happens many times it will fill the muffler
This form of water intrusion is avoided by the proper and endanger the engine This could easily be the case for of an anti siphon
valve in the sea water circuit power boat not using its generator or for a sailboat not using
between the sea water pump outlet and the water injected its engine If you suspect that water is intruding run the
exhaust elbow inlet Refer again to the generic drawing of a engine frequently until the suspected problem is water line installation
utilizing a and fixed
water lift muffler
NOTE Running the engine or Genset will normally preclude
water intrusion as the exhaust flow under pressure prevents
water from entering the exhaust outlet
Cranking the Starter Draining the Muffler
Prolonged cranking of the starter may cause excessive sea
water to build up between the engine and the high point
Each time cranking is interrupted additional water may spill
back into the muffler In time this cumulative spill back can
flood the engine Unusual cranking andor cranking
interruptions must be monitored and the muffler drained
before excessive water buildup occurs This may be made
more convenient by installing a suitable noncorrosive valve
at the muffler drain is the difference between the highest underside of the boat
deck near the and the anti siphon valve K
should be minimized There is every reason to attach valve directly to the underside of the deck There
is no reason to fail to take full advantage of this height because it forms the only barrier to by siphoning The anti siphon valve must be well
above the worst case water level under all conceivable condi
tions of boat trim boat operation sea conditions and heel
angle The antisiphon break and the exhaust hose point
should be located as near to the boats centerline as on sailboats due to large and steady healing The
siphon must be accessible for 14
EXHAUST SYSTEM Valves Dry Stack Exhaust types of check valves are available and suitable
for Commonly seen on commercial fishing boats dry stack
exhaust runs Examples are inline check valves offered by exhausts can also be used on trawler style pleasure boats A
some exhaust component manufacturers and flapper valves dry stack exhaust directs the exhaust gas straight from the
on exhaust outlets None of these may be considered as an generator or engine without obstructions A dry stack to a good installation They

15 psi 01 kgcm2 overall threaded at each end and installed as close to the
engine as possible This flexible section should be installed
with no bends and covered with insulating material The
exhaust line should be properly supported by brackets to
eliminate any strain on the manifold flange studs
WARNING Do not install rubber hose with sharp
bends as this will reduce efficiency Do not use rubber
hose on dry type exhaust applications Doing so may
cause hose failure and leakage of deadly exhaust gas
Make sure that the water discharge into the rubber hose
section is behind a riser elbow or sufficiently below the
exhaust flange so that water cannot possibly flow back into
the engine Also in custom systems make sure that entering
raw water cannot spray directly against the inside of the
exhaust piping Otherwise excessive erosion will occur
