1. Unscrew nut (3) one turn.
2. Insert pin in head of adjusting screw and
adjust position of screw, in or out, when
engine is running at maximum speed.
3. Set position of adjusting screw so that
maximum propeller pitch corresponds to
the optimum value of fu11 speed rpm from
the point of view of vibration and boat
speed. This engine speed will depend on Fig.9
the boat's size and huIl form. It win nor-
mally he in the region of 200) rpm and
must not exceed 2250.
Note that the propulsive power of the engine (propeller torque) is nearly constant
for engine speeds in the range 1800-2(XX) rpm but falls at higher engine speeds.
This means that, with a controllable pitch propeller, maximum propulsive power will
he obtained in tros engine speed range. There is therefore little point, in the case of
most boats, of running the engine at the maximum of 2250 rpm. Only if the boat is
particularly easy to propel will the use of maximum rpm result in higher boat speed.
If the boat is used for fishing, it is generally preferable to use maximum pitch when
towing lines and a slightly reduced pitch for ful1 speed.
RUNNiNG-IN A NEW ENGINE
A new engine should not he subjected to any unnecessary stress or loading. Run the
engine carefully to begin with using full speed only for short periods. Increase the
engine loading gradually during the initial2S hours running.
Remember thaI treating the engine sensibly during the running-in period will
lengthen the life of the engine appreciably.

ElECTRICAl EQUIPMENT
Altemator 12V 35A (SOOW) S. E. V.
The alternator produces 3-phase altemating current. The altemating outputs of
each phase are rectified by means of 6 silicon diodes (3 positive and 3 negative
diodes). During starting, the field current is fedto the rotor trom the battery via the
regulator.
The alternator must therfore only be run ij the battery is connected. Ij a battery iso-
lating switch is fitted the engine must not be started until battery has been switched
on.
Use of an altemator ensures continuous charging of the battery even if the engine is
idling for long periods.
The SEV altemator bas an integral electronic regulator.
.
Follow the connection diagram precisely. Incorrect connection will probably
damage alternator or voltage regulator and repair will be expensive.
In addition to the above:
1. Check carefu1ly that all connections are made as shown in diagram.
2. The altemator must never be run unless both battery terminals and the
regulator are connected. Remove the altemator drive belt before discon-
necting the battery.
3. If the battery is to be charged trom an extemal source, first disconnect bath
battery terminals.
4. When welding on board (steel hu1ls), disconnect the battery negative terminal
beforehand.
Starter, BOSCH
It is very important that the starter should not be exposed to sea water. The engine
must not be started if the level of water in the bilge reaches to the flywheel. Pump
out sufficiently to avoid splashing the starter.
Battery
The battery should be contained in its own box made of wood or special plastic and
it should be positioned as near to the engine as possible. The battery box should be
0( weU ventilated and the battery firmly secured.
Check the battery regularly. Top up with distilled water to keep the electrolyte level
1/2 cm-1 cm above the plates. After topping up in cold weather, run the engine for a
while to ensure circulation of the electrolyte. Keep the battery terminals and cable
clamps clean. Remove any oxidation and coat lightly with vaseline. Make sure the
cables are tightly clamped onto the terminals.
The electrical equipment is not covered by the engine guarantee.

CARE AND MAINTENANCE
To achieve good results in operation, it is important to give the engine the attention
recommended. Tbe following section includes general guidance, descriptive notes
and sketches to assist in routine maintenance.
If the specified maintenance is carried out correctly and at the recommended
intervals, engine deterioration will be minimised and optimum performance will be
ensured.

A. LUBRICATING OIL SYSTEM
'" Tbe lubricating oil system is pressur-
ised, the oil being pumped from tbe .
sump oil filter (1) via tbe oil pump (2)
(gear pump fitted inside pump housing) and, under pressure, to the fu1l
flow filter (3). Oil channels in tbe
crankcase/ main hearing housing provide lubrication for crankshaft main
hearings and connecting rod hearings.
A pulsed oil flow is also fed via the
camshaft (5) and the pipe (6) to tbe
~ rocker arm hearings before being re-
turned to the sump.
. Tbe oil pressure is limited by the oil
pressure relief valve (4) fitted behind Fig. 12
tbe oil filter (see Figs 12 and 18). Tbe
oil pressure is indicated on the
pressure gauge (7).
LUBRICATING OIL
Tbe engine oil should be checked daily before starting. Tbe dip stick is located in
the governor cover and bas two level marks. Tbe upper mark indicates tbe oillevel
. when the sump is fu1l (4Iitres). Tbe level shouJ.d never be allowed to fall below the
lower mark.
To ensure effective lubrication and long lasting engine cleanliness, it is important to
use an approved oil to tbe correct specification.

D. COOLINGWA1ER
The cooling water pump is a diaphragm pump
consisting of a rubber diaphragm sandwiched
between the pump housing and the flange
beneath.
The rate of flow of cooling water can be
regulated by means of the gate valve to give a
suitable cooling water temperature with the
engine fully loaded. This temperature should be
between 40° and roo C.
At reduced speed this temperature will fal!
somewhat. This wi1l not damage the engine and
anode (plug) is fitted to the forward end of the

The fresh water tank (2) (1974 1
model) is separate from the ---7 - - I
silencer and is mounted on top 2 - - . I
of it.
The thermostat (3) is located in
the silencer where it adjoins the
fresh water tank.
The keel cooler (4) is mounted
on the underside of the huIl.
If preferred, it is possible to fit
an intemal heat exchanger in
place of en extemal cooler.
). This requires a separate pump.

"' . through the system until the
. ~ tank is full. Check that there -~::
~

See page 30.
When first starting, fill the tank
with clean fresh water, or a
water / antifreeze mixture, via
the filler with pressure cap (1).

Operation
Until the cooling water bas warmed up the water flow is through the silencer cooling
jacket channels, out of the rear of the silencer and via the by-pass pipe back to the
water pump.
When the engine bas warmed the cooling water up to 55° C, the thermostat begins
to open and divert part of the water via the fresh. water tank to the extemal cooler
(or intemal heat exchanger where it is cooled before once more entering the water
pump).
- When in operation, the termostat will automatically distribute the cooling water
between extema! cooler and by-pass pipe, thus maintaining the cooling water
'" temperaturebetween55° and 75° C. (130-170° F.)
In case onncorrect operation (water temperature too high or too low) check:
7. Cracked cylinder head causing compression leak into cooling
jacket. Symptom will be heavy bubbling in water tank. Most
easily confirmed by letting the motor cool and then letting it idle.
Winter Use
For use in winter the system should be filled with an approved make of glycol antifreeze. With standard piping the system holds approximately 5 litres. The
addition of 1 litre antifreeze (4 litres water) affords protection down to -80 C
while 1.5 litres of antifreeze will protect down to -150 C. Flush the whole
system with water before filling with antifreeze solution. After filling, run the engine
for 3 minutes to ensure thorough mixing. When using glycol antifreeze it is not
necessary to drain the system before or after winter use (or laying up) provided thai
the coolant remains clean and tree of rust flakes. If this is not the case the system
must be flushed through.

23. CHECKING COOLING WATER LEVEL (Weekly):
A weekly .-;:heck is generallyadequate but if the engine is being run continuously in
warm weather, a daily check may be necessary. 1
1. The engine cooling water must have cooled
down sufficiently for the fresh water tank to
be touched without discomfort.
2. Open the pressure cap carefully. Beware of
any water spraying out since this can scald.
3. Check the level and top up if necessary to
bring the water level up to the lover edge of
the filler neck.
.. If the system contains anti-freeze, it should be
. topped either with a solution of the same _n
strength or with neat anti-freeze. (See page 30.) ~

into position and secure firmly.
IMPORTANT:
Ensure that the pump spigot (see Fig 54, item 6) engages with the slot in the
governor arm (Fig 54 item 5). This caD be feIt as a slight "click" or dead movement when the governor controllever (8) is turned in the "stop" position.
42. CONTROLLABLE PITCH PROPELLER
The propeller blade pitch is altered by means of the drive block (4), the whole shaft
being moved in and out. The drive block thus both transmits the engine power and
controls the pitch of the propeller blades.
The thrust hearing is located in the forward end of the propeller boss and consists
of three nylon rings, two (2 and 3) to take the ahead thrust and ODe (the centre oDe,
not shown) to take the astern thrust.
Pitch Control Stiff:
A. If the pitch control is stift to operate, it
may be due to lack of grease in the 7
propeller boss, poor alignment between .
engine and propeller shaft, or to stiff- 1
ness of the drive block within the pro-
" peller boss.
I B. Check shaft alignment by inserting a 2
feeier gauge between the coupling flange
and the engine drive flange, and then try
; with the two flanges disconnected.
If pitch control then works freely and the
shaft alignment is correct, the boat must
be slipped for examination of the pro-

3. Remove the boss and propeller blades. Check whether the drive block (4) is
cracked. If not, the stiffness can possibly be cured by careful filing of the drive
block faces.
If the drive block is cracked or loose on its threads, it must be replaced.
4. If the propeller blades are damaged, they must be repaired so that they are again
identical. Any blade differences will cause vibration leading quickly to wear on
the shaft.
Assembly.
1. Fit the blade tap blocks (5) to the blade taps (6).
2. The marked blade (7) is positioned with its tap block (5) engaged in the
recess on the marked side of the drive block. One half of the propeller boss (8) is
then fitted itl position from the port side in such a way that all the marks point in
the same direction.
3. The other blade is then fitted with its tap block (5) engaged in the remaining
recess in the drive block.
4. Fit the thrust rings, ensuring that the raised beaded side of each rings runs in
contact with the corresponding stern bearing surfaces. Fill stern propeller boss
with grease.
5. Fit the remaining half of the propeller boss and screw home the boss screws
which are locked with lork washers (1).
The propeller shaft is manufactured trom stainless steel and bas parallel threads.
I;:nsure therefore that the replacement drive block is fitted the correct way round

43. REVERSE GEARBOX ~o..
The reverse gearbox works on the principle of self-adjusting CODe clutches for ahead
and astern drive. When the gear lever is moved, the gear shaft (4), together with
flange coupling (7) and propeller shaft, is moved forward for ahead drive and back-
ward for reverse.
The clutch is held engaged by the propeller thrust. To avoid a degree of clutch slip
during engagement, the clutch lever should be engaged with a light pressure. As
soon as the propeller bas begun to generate thrust, the clutch will hold in. The lever
must not touch engine casing etc.
1 The nature of this method of clutch operation makes it important that exact align-
ment between engine and propeller shaft is maintained. Any misalignment fuld

The injection pump is rugged and reliable provided that the fuel Dil is clean and free
of water, but it is a precision product and will not stand improper use.
The pump cao be removed foT checking but removal of the delivery valves (2) should
only be carried out by qualified service representatives, as should any repairs to the
pump.
The pump cao be taken out without removing the govemor cover.

Assembly:
4. Insert screwdriver (5) in the gap in the pump shim{ 6) and pump housing so that
the governor arm (Fig S4 item 5) can be carefuUy levered out and held in that
position.
5. Hold the pump as shown. Ease it downwards into the opening until the lowest
part of the pump bas passed the governor arm and hold in that position. Withdraw the screwdriver, turn the pump clockwise through ~o and press it down
into position.
6. Ensure that the fuel pump spigot engages with the slot in the governor arm. This
can be feIt as a slight "click" or dead movement when the governor controllever
is moved in the "stop" position.
G. WINTER LAVING UP
Before laying the boat up lor the winter, protect the engine as foUows:
Change the oil in crankcase and clutch or reverse gearbox.
Grease aU nippies.
Oose gate valve and allow engine to idle lor half a minute to expel any water trom
the exhaust hose.
Drain the water trom engine, silencer, water pump and piping.
For sea water cooled engines, flush cooling system through with fresh water.
For fresh water cooled engines with closed cooling system, there is no need to drain
provided that anti-freeze bas been added. See "Fresh Water Cooling". If the system
is drained, any external cooler must be blown dry.
If a heat exchanger is fitted, the gate valve must be closed and sea water drained
trom the heat exchanger. Open impeller pump cover, extract impeUer and replace
cover.
Unscrew start cigarette plugs and spray 10 shots (about 10 cc) of lubricating oil into
each cylinder. Turn the engine over a lew times. Repeat once or twice during the
';, r: cource of the winter.
'ic
!:"'~ Oean engine externally and touch up with engine paint.
, Keep engine covered.
Drain off any condensed water in the fuel tank and top up with fuel.
Remove battery trom boat, charge and store in a dry trost-tree place. The battery
should be recharged at intervals two or three times during the winter.
Disconnect the flange coupling and separate slightly. This ensures that the
shaft will not be damaged if the huIl should distort during the lay-up.

a ..';;.; .;tJ !f
:,; ."
PREPARATION AFTER WINTER LAY-UP:
When preparlng the engine following winter lay-up, it pays to spend as much time
on the work as necessary .
When the boat bas been re-floated, the engine E
alignment should be checked.
If the engine is supported in rubber mounts, the ~;
adjusting nuts (0) above and below the support
frames should be checked. Also check the bolts(E).
Sea Water Cooled Engines:
Inspect the zinc anode plug (also tor fresh water Fig. 62
cooled engines) at the forward end of the silencer.
Renew if necessary .
Oose drain cocks. Make sure that the gate valve is open and that the exhaust hose
is connected to the silencer.
Fit a fully charged bartery and connect it as shown in the wiring diagram.
NOTE: Never start the engine before the alternator and regulator have been
connected to the bartery. Adjust V -belt tension.
Check that there is fuel in the tank. Drain off sediment.
Check that there is oil in engine and clutch or gearbox. Grease all nippies and
propeller boss.
Fresh Water Cooled Engines (without anti-freeze):
Inspect zinc anode plug at the forward end of the silencer. Suction and return
hoses must be connected to the engine and to the extemal cooler. Fill system
with clean fresh water.
'~
J) CHECKING THE ALlGNMENT
- The alignment. of engine and propeller sha.ft b" ",i:!
~ should be checked. a.iter the boat bas ?een m \ C!;'c
~ the water a sufficlent length of time to '
I permit the bull to set. The alignment is
.è controlled with a feeier gauge between the
coupling flanges (see fig 63), in 4 positions
up, down and laterally. (.
If required loosen engine fixing bolts and fit
';0: shims under frames until flanges are exactly ~',
~ parallel. Check again after engine is fixed. Fig.63 --@.
