GENERAL INFORMATION
IMPORTANT: read this manual carefully and thoroughly, particularly WARNING,
CAUTION and IMPORTANT information in bold type, such as this paragraph.
WARNING: It is recommended that the battery
cables be removed from the battery when the boat
is placed in storage, on display or in transit. This
will eliminate the possibility of the engine
accidentally starting and causing damage to the
engine due to lack-of water.
Installation of the propeller shaft and associated mounting
parts is not outlined in this manual. The propeller shaft angle
and propeller location must be determined by the boat
builder to meet the requirements of the boat design.
Propeller shaft diameter should be of sufficient size for the
type of application. The following propeller shaft couplings
are available from PMC.

Engine and Transmission Identification
The engine model and serial number are located on the
intake manifold at the rear.
The transmission model, serial number and ratio is located
on the transmission case.
Except for V drives on some applications the propeller shaft
rotation -with the transmission in forward gear on engines
equipped with 1:1, 1.5:1, 2.5:1 and 3:1 transmissions - is the
same as engine rotation.
Propeller shaft rotation - with the transmission in forward
gear on engines equipped with 1.9:1 transmissions - is the
opposite of engine rotation.
On V drive engines both engines may turn the same
direction and have the propeller rotation changed in the V
Drive.
On all engines the Serial # plate indicates both engine and
propeller shaft rotation. Example: PLD-WV-R20 and
PLD-WV-L20. The L following the P indicates the engine
rotation. The R and L following the V and preceding the 20
indicates the Propeller Shaft Rotation. The engines must be
installed accordingly to insure proper propeller rotation.
1
CAUTION: The Warner Gear shift lever MUST BE IN
FORWARD; that is, positioned over the letter "F"
which is embossed in the case casting for
FORWARD gear. Likewise, the shift lever must be
positioned over the letter "R" for REVERSE gear
on all gear models.
Engine Alignment and Mounting Adjustments
The engine must be aligned to the propeller shaft within
.003' (.076mm) or less when measured between the mating
surfaces of the transmission coupling flange and the
propeller shaft coupling flange. To obtain correct engine
alignment, insert a feeler gauge between the coupling mating
faces and adjust engine position as required to place the
mating surfaces parallel to each other within .003' (.076mm).
This clearance must be maintained at all times and at all
positions of the coupling. To complete alignment turn the
shaft coupling 180* from the starting point after the engine
and shaft are aligned to within .003'. Test for proper
clearance. If out readjust the engine to proper clearance.
Retest by turning coupling 90' at a time and testing to insure
alignment at all points through the 360' circle.
Front mounts are adjusted by loosening the upper lock nut
on the mount stud and trunion locking stud nuts and tapping
on the nuts to loosen the studs on the trunion The mount can
then be raised or lowered by screwing the lower nut up or
down in the desired direction and side to side by prying
against the block. CAUTION: Side to side adjustment must
be limited to a maximum 1-3/4: extension of the trunion
from the mount bracket. Extension of more can cause
bending of the trunion or possible mount failure.
Rear mount adjustment is made by loosening the stud lock
nut and turning the stud in the proper direction for vertical
adjustment and by loosening and tapping the nut on the lock
studs to free the rear trunions and adjust in the same manner
as the front for side to side adjustment. CAUTION: Be
certain to lock the lock nuts on the adjusting and lock studs
when adjustment is completed.
After alignment is complete lag and/or cross bolt mounts
securely to the stringers.
The engine mounts are adjustable to permit raising or
lowering the engine and also moving the engine to the right
or left. It is recommended that, when the engine bed is
installed in the boat, it is positioned so that engine alignment
is as close as possible. After engine mounts have been
fastened to the engine bed, final alignment should be done
by adjusting the mounts as follows:
2
Water Pick-Up Installation
Water pickup must be large enough to permit sufficient
water flow to engine seawater pump in order to provide
adequate engine cooling. Pleasurecraft Marine recommends
that a sea strainer be installed on all boats equipped with
transom or thru-hull water pickups to prevent foreign
material from entering and clogging engine cooling systems.
Engine damage that results from a clogged cooling system,
will not be covered by Pleasurecraft's Warranty.
In the interest of safety, it is recommended that a sea cock be
installed between water pickup and sea strainer.
Water pickup should be located as close to seawater pump
inlet as possible and in an area where an uninterrupted, solid
stream of water will flow past it when boat is underway.
Seawater pump inlet is designed for I' I.D. hose. Hose must
have adequate wall thickness to prevent collapsing caused
by pump suction. Hose should be fastened securely at
connections with hose clamps.
EXHAUST SYSTEM
When designing the exhaust system, it is very important that
the following points are taken into consideration:
1. System must not cause an excessive amount of back
pressure. Back pressure must not exceed 4' (10.2cm) of
mercury when measured with a mercury manometer at
the exhaust manifold outlets. Minimum exhaust hose
sizes are as follows:
Dual Exhaust - 3' I.D. (7.6cm)
Single Exhaust - 3-1/2' I.D. (8.9cm)
2. System layout and construction must prevent cooling
system discharge water from flowing back into the
engine and also prevent sea water from entering the
engine via the exhaust system.
Exhaust Hose Installation
The exhaust hose, which connects to the exhaust manifold
riser should be connected so that it does not restrict the flow
of discharge water from the elbow.
Both exhaust manifolds are water-cooled, and all cooling
system water is discharged thru openings which are located
inside the risers. To prevent discharge water from flowing
back into the engine, the exhaust piping must not be higher
than the manifold outlet at any point.
It is the obligation of the boat manufacturer or installing
dealer to correctly locate the engine for installation.
Therefore, if water is present in the exhaust manifolds or
combustion chambers of the engine, the product has not
caused the problem, unless there is a defective part.
Hoses, which are connected in a manner to bend in front of
the exhaust outlet, will prevent discharge water from flowing
around the entire inside diameter of the hose and will cause a
hot spot that may burn through the hose.
The exhaust system should have no sags or low spots to
accumulate water. Sharp bends of more than 45 degrees in
the exhaust lines should be avoided. The exhaust lines
should slope toward the transom at a rate of at least 1/2 in.
per foot with vessel at rest. Exhaust pipe size should not be
restricted. Exhaust back pressure will create poor
performance, high fuel consumption, and severe engine
damage.
Exhaust transom flanges should be above the water line, and
the exhaust lines should be self-draining.
The system should be periodically inspected for leaks and
general condition to prevent leakage of water and exhaust
gases into the hull. Flapper valves are suggested to be used
on all exhaust systems.
Fuel System Installation
Coast Guard Regulations must be observed when installing
fuel system. Fuel systems should be installed in accordance
with the standards of industry associations and applicable
federal standards.
Engine Compartment Air Intake
The engine compartment must be properly vented to provide
a sufficient amount of air for engine breathing. Air intake
and exhaust openings must be large enough to provide an
unrestricted volume of air under all operating conditions.
Engine compartment ventilation also should conform to
Coast Guard Regulations.
Control Cable Adjustments
After installation of controls and cables proceed with the
following adjustments.
Shift Cable
1. Set control lever in neutral position.
2. Position shift selector on the warner gear into neutral
position. In moving the selector from neutral to forward
to reverse to neutral three distinct detent positions will
be felt.
3. Adjust the connector on the control cable so the
connector slips freely into the hole in the selector arm.
4. Remove the connector from the selector arm and move
the selector and control lever into the forward position.
In this position the shift lever must cover the "F" cast
into the transmission case. The connector should slip
freely into the hole in the selector arm.
3
5. Repeat step #4 with the selector and control levers in
reverse position.
If the movement of the connector does not correspond with
the movement of the selector lever it will be necessary to
readjust the remote control head to provide the proper
direction of control cable travel.
CAUTION: Transmissions operated in reverse to
propel the boat forward will fail early. Engine and
propeller rotation must be matched according to
the Serial Plate.
Throttle Cable
1. Place control lever on single lever control into forward
gear without advancing the throttle and on a twin lever
control in the fully closed position.
2. Adjust the connector so that it slips freely into the
connector socket and lock into place.
3. Position throttle into the full throttle position after
blocking the choke open. Check to see if the throttle
valves are in the full open position on both the primary
and secondary side if so equipped.
If valves do not open fully make necessary adjustments
at either control head or cable connector to insure full
opening. Repeat steps #1 and 2 to insure proper idle
settings and adjust if necessary.

MISCELLANEOUS INSTALLATION INSTRUCTIONS
WARNING: Before starting engine always ventilate
engine compartment by opening engine hatch or, if
equipped, operate bilge blower a sufficient amount
of time to remove any gas fumes from engine
compartment. It is doubly important to check for
fuel spillage or leaks after repair, refueling or
maintenance before starting engine. Remove
battery cable from battery before attempting any
maintenance, repairs or when boat is placed in
storage or in transit.
Check Before Running
1. Engine oil level.
2. Transmission lubricant level.
3. Engine drain plugs installed.
4. Leakage (fuel and water lines and connections).
5. Throttle shutters full close at idle (neutral).
Check While Running (See "Caution", Below)
1. Oil pressure 35 to 40 PSI (2.5 to 2.8kg/cm2) (Approx.)
at 2000 RPM.
2. Water temperature 1401-1600 R/W and 180'-2000 F/W
3. Idle RPM (550-600) in gear
4. Maximum forward RPM 4,400
5. Shifting linkage (forward, neutral and reverse) for shift
lever in detent and proper direction.
6. Leakage (water, oil and fuel)
Check After Initial Run
1. Engine alignment
2. Engine mounting fasteners are tight.
3. Engine oil level
4. Transmission oil level and shift connections.
CAUTION: Do Not Operate Engine without Cooling
Water Flowing thru Water Pump, or Neoprene
Water Pump Impeller Will Become Damaged.
Attach Water Hose to Pump Inlet. Run Engine
Slowly (650-700 RMP) in Neutral to Circulate Water.
Watch Water Temperature Gauge to Prevent
Overheating.

Operating Limits (See Specifications for
Your Model)
Maximum RPM at wide open throttle under normal load
conditions can be controlled only by propeller pitch,
diameter, and design. It is essential that the propeller
selected does not overload or underload the engine. Extreme
overloading resulting in low RPM's at wide open throttle
will deliver poor performance, poor fuel economy, and
eventually result in engine damage. Underloading will result
in high RPM, poor fuel economy, and engine damage, if
operated above recommended maximum RPM's.
Do not operate at high RPM's in neutral. Operation in
extremely shallow water can cause sand, silt, and gravel to
be pulled into the cooling system. This can create excessive
water pump wear, and in extreme cases may deposit in the
engine block water jackets and seriously damage the engine
from improper cooling. Heavy weed growth can plug oil
coolers and water intakes and cause damage. If operation
under these conditions is necessary, a good quality sea water
strainer or filter should be installed. The installation of a
fresh water cooling system can reduce the danger of engine
damage from this cause.
ALWAYS OBSERVE HIGH SAFETY STANDARDS
AND COURTESY AFLOAT.
Propellers
Propellers can affect the performance of your boat in many
ways. Selection of the proper propeller for your application
is vital. In most cases, the selection is made by the
Boatbuilder for best over-all performance; however, many
variable factors, such as heavy loads, high altitude, hull
balance, etc., can contribute toward rendering the "standard"
propeller unsuitable, since the application is no longer
"standard."
Many undesirable results can occur from a propeller not
properly matched to the specific application; high RPM's,
low RPM's, cavitation, vibration, steering torque (stem
drives), drumming or rumbling noise, high fuel
consumption, poor efficiency, and even electrolysis damage
(stem drive). When changing propellers, extreme care should
be taken to select a propeller which allows the maximum
engine RPM's with normal load to be within the proper
range for the particular model. See the engine specification
chart in this book for "Maximum RPM."
The use of brass or bronze propellers on stern drives in salt
water or water with high mineral or acid content is not
recommended, due to the possibility of electrolytic attack
and corrosion of the outdrive housings.
If the propeller is bent, broken, out of balance, or otherwise
damaged, limit operation to bare necessity until the propeller
is repaired or replaced.
Directional References
Directional references are given as they appear when
viewing boat from stern, looking toward bow. Front of boat
is bow; rear is stern. Starboard side is right side; port side is
left side.

Fuel Requirements
Use any good grade automotive regular or premium gasoline
with a minimum average octane rating of 88* (93 research)
in your PCM engine.
An 86* average octane (90 research) gasoline may be used if
the gasoline described above is not available; however, the
ignition timing MUST BE retarded 41 to prevent harmful
detonation.
*New U.S. Regulation requires posting average of
research and motor octane.
PCM reserves the right to refuse warranty on parts which are
damaged -when using improper gasolines.
Replacing Fuel Filter
PCM recommends the use of a Remote Mounted fuel filter
and/or water separator and fuel filter on all its engines. Fuel
filters are not standard with PCM engines, however, we do
offer them as an option to all Boat Builders and Dealers. If
your Boat is not equipped with a fuel filter see your PCM
Dealer. He can provide you with the proper parts and
installation service to protect your engine's fuel system.
When replacing the fuel filter element, follow the
manufacturer's instructions and the following cautions.
CAUTION: Be careful of spilled fuel. Gas vapor
buildup is explosive.
NOTE: DO NOT re-use; always replace with new filter and
gasket.
CAUTION: DO NOT operate engine without cooling
water flowing thru water pump, or water pump
impeller will be damaged, and subsequent engine
damage may result.

Transmission
Fluid Type
Use only automatic transmission fluid type "A", suffix "A"
in this transmission. This fluid is trade named Dexron.
Change Frequency
Change transmission fluid once each year.
Maintaining Transmission Fluid Level
Transmission fluid level should be checked frequently and
fluid added if necessary. Level must be maintained between
the two marks on dipstick.
CAUTION: Be careful of spilled fuel. Gas vapor
buildup is explosive.
1. Carburetor inlet filter is located in primary float bowl in
fuel inlet fitting.
CAUTION: Use care so fuel is not spilled.
2. Remove fuel line and fuel inlet fitting from carburetor.
3. Wash filter in solvent. Dry with compressed air.
4. Install new gasket on fuel inlet fitting. Install fitting into
carburetor and tighten. Install fuel line.
CAUTION: DO NOT operate engine without cooling
water flowing thru water pump, or water pump
impeller will be damaged, and subsequent engine
damage may result.
5. Run engine and check for gasoline leaks.
Valve Adjustment
Hydraulic valve lifters require little attention. Lifters are
extremely simple in design, readjustments are not necessary
and servicing requires only that care and cleanliness are
exercised in the handling of parts. The best preventive
maintenance for valves is frequent changes of engine oil.
Cylinder Head Torque and Sequence
Cylinder head bolts are tightened in 3 progressive steps.
Torque all bolts in sequence and finally to 100 ft. on 351
engines and 70 ft. lb. on 302 engines.
Maintain fluid level as follows:
1. Boat must be at rest in the water and engine running.
2. Turn dipstick "T" handle counterclockwise and remove
dipstick.
3. Wipe fluid off dipstick and set in position in
transmission fill hole.
4. Remove plug and note level indicated on dipstick. Add
fluid, if required, to bring level up to the top mark.
5. Reinstall dipstick and turn "T" handle clockwise to
tighten.
