FEATURES
When a replacement is required, see your VOLVO
PENTA dealer. If other than VOLVO PENTA anodes are
used, make sure they are equivalent or galvanic
corrosion protection will be lost. (If additional electronic
or electrical equipment is installed, each should have an
individual anode or grounding device. All grounding
devices must be interconnected. Follow equipment
manufacturers recommendations.) The anode on the
unit is designed for the VOLVO PENTA Power Jet only.
Adding additional metal to the bonding system requires
additional anode protection.
Note Inspect the anode every 14 days, or more
frequently if used in extremely salty water. If the anode
is 2/3 its original size (1/3 eroded), it should be
replaced.
Boats that connect to an AC power source (shore
power) require protection against galvanic and stray
current corrosion. For protection, a galvanic isolator
can be installed in the grounding (green) wire between
the boat and the shore power outlet on the dock. The
isolator blocks direct current (DC) flow, but permits the
passage of alternating current (AC), thereby providing a
path for ground fault currents.
Note If a boat is connected to an AC power source
(shore power) and it is not equipped with a galvanic
isolator, additional sacrificial anodes may be required to
handle the added corrosion potential.
If your boat is not equipped with an emergency
STOP switch and it falls into one of the following
categories, installation of an emergency stop
switch is recommended.
 High performance sport boats
 Small runabouts
 Boats with sensitive steering
 Boats where the distance from the top of the
gunwale down to the drivers seat is less than 12 in.
(30,5 cm)
See your VOLVO PENTA dealer for installation of an
emergency stop switch.
SACRIFICIAL ANODE ________________
3A sacrificial anode His attached to the top of the
trim plate under the Power Jet. An anode is slowly
eroded away by galvanic action and requires inspection.
If an anode is subjected to frequent wetting and drying,
remove any scale or oxidation with sand paper. Do not
use a wire brush or emery cloth to maintain
effectiveness.

FEATURES
CIRCUIT BREAKERS AND FUSES _____
1The engine and boats electrical system is
protected by main circuit breaker Aand fuses against
current overload. If a circuit breaker trips, it can be reset
by pushing the red button. Circuit breaker Bis not
connected and not used. A blown fuse must be
replaced. Circuit breakers or fuses that repeatedly fail
indicate a problem requiring immediate attention. See
your VOLVO PENTA dealer.
STEERING _________________________
2VOLVO PENTA Power Jets feature a manual
steering system. This works in conjunction with the
helm and steering cable to move the tiller arm C, thus
moving the steering nozzle and rudder. The steering
nozzle directs the high pressure water stream in a
direction that causes the boat to move in the desired
direction.

or spark knock, and the engine is properly tuned,
change to a higher octane fuel.
If your boat will not be used for 30 days, fuel stabilizer
is recommended. To prevent gum formation from stale
gasoline, add fuel stabilizer to the gasoline in the
amounts recommended on the bottle. Fuel stabilizer,
part number 3855832-6, is available from your VOLVO
PENTA dealer.
GASOLINES CONTAINING ALCOHOL __
Many gasolines sold today contain alcohol. Two
commonly used alcohol additives are Ethanol (ethyl
alcohol) and Methanol (methyl alcohol).
Read your boat owners manual to determine if the
boats fuel system is compatible with alcohol blended
fuels. If it is compatible, your engine may be operated
using gasolines blended with no more than 10% Ethanol
meeting the minimum octane specification. Do not use
any gasoline which contains METHANOL.
Note Serious damage will result from the continued
use of fuel containing METHANOL.
Fuel leakage can contribute to a fire and/or
explosion.
If you use gasoline containing ethanol, be aware of the
following:
 The engine will operate leaner with ethanol blended
fuel. This may cause engine problems such as
vapor lock, low speed stall, or hard starting.
 Ethanol blended fuels attract and hold moisture.
Moisture inside fuel tanks can cause corrosion of
the tank material. Inspect fuel tanks at least annu-
ally. Replace fuel tanks if inspection indicates leak-
age or corrosion.
 Inspect nonmetallic parts of fuel system frequently
and replace if excessive stiffness, deterioration, or
fuel leakage is found.
GASOLINE REQUIREMENTS __________
Note USE UNLEADED FUEL ONLY.
Gasoline is extremely flammable and highly
explosive under certain conditions. Always
stop engine and do not smoke or allow open
flames or sparks near the boat when refueling
gas tanks.
When filling the gas tank, ground the tank to the
source of gasoline by holding the hose nozzle
firmly against the side of the deck filler plate or
ground it in some other manner. This action
prevents static electricity buildup which could
cause sparks and ignite fuel vapors.
Maximum performance requires the use of lead-free
gasoline with the following minimum or higher octane
specification:
Inside the U.S. (R+M)/2 (AKI) - 89
Outside the U.S. (RON) - 93
If fuels with 89 AKI (93 RON) octane or higher are not
available, the ignition timing will have to be retarded so
lower octane fuels, with minimum 87 AKI (90 RON)
octane, can be used. See your authorized VOLVO
PENTA dealer. When ignition timing is retarded, a slight
decrease in power can be expected.
Note Engine damage resulting from the use of a
lower octane gasoline than 87 AKI (90 RON) is
considered misuse of the engine and will void your
engine warranty.
Detonation or spark knock in a marine engine is not
necessarily audible. Overheating and continued running
(dieseling) after ignition shut off are indications of
detonation in a marine engine. If you suspect detonation

REMOTE CONTROL OPERATING
INSTRUCTIONS _____________________
Familiarize yourself with remote control operation
before starting engine.
Your boat may be equipped with one of the following
remote controls:
 Single lever side mount or binnacle mount control.
 Twin lever controls, one lever controls engine
speed (rpm) the other lever controls thrust direction
ahead or astern.
Your boat may be equipped with remote controls other
than those described above. If VOLVO PENTA controls
are not used, ask your VOLVO PENTA dealer for
operating instructions for the remote control system
used on your boat, since operation and function may
differ from VOLVO PENTA remote controls.
VOLVO PENTA controls have the following important
features:
 A single lever, which allows you to select neutral,
forward, or reverse thrust; regulates engine speed; and
ensures changing thrust direction is done at low engine
speed.
 A start-in-neutral-only feature, which prevents you
from starting your VOLVO PENTA Power Jet in forward
or reverse thrust position.
 Binnacle mount control (not shown) has a neutral
lock ring to prevent accidental shifting. It must be
squeezed upward to permit shifting from neutral into
forward or reverse.

OPERATION
Your boat should be equipped by the
manufacturer with a remote control with
protection to prevent starting in either forward
or reverse thrust. Use only a remote control unit
with start-in-neutral-only feature. This feature
can prevent injury resulting from unexpected
thrust being applied and sudden, uncontrolled
movement of the boat.
The shift mechanism of all VOLVO PENTA controls
can be disengaged to allow for easier starting and
engine warm-up.
1Single Lever Side Mount Control
To disengage shift mechanism:
1. Place control handle in neutral (N) position.
2. Press and hold the neutral lock button (2).
3. Move control handle (1) forward to increase throttle
(most controls have a starting detent position).
The neutral lock and shift mechanism will
automatically engage when the control handle is
returned to neutral position (N).
(R) Reverse Shift Range
(T) Reverse Throttle Range
(F) Forward Shift Range
(T) Forward Throttle Range
2Binnacle Mount Control
To disengage shift mechanism:
1. Place control handle in neutral (N) position.
2. Press and hold the neutral lock button (2).
3. Move control handle (1) forward to increase throttle
(most controls have a starting detent position).
The binnacle mount control operates the same as the
single lever side mount control shown and described
above.
For Other Controls
Many engine controls allow the shift mechanism to be
disconnected from the throttle control for easier engine
starting and warm up. The procedure given above for
the binnacle mount control will disengage the shift
mechanism of most control systems. See your VOLVO
PENTA dealer if you have any questions on how to use
your engine control.
Note Most shift mechanisms will automatically
engage when the control handle is returned to neutral.

STARTING COLD ENGINE ____________
1. The engine may require priming prior to starting. To
prime the engine, proceed as follows:
 Place ignition switch in the OFF position.
 Disengage shift mechanism.
 Move control handle to the full throttle position (this
operates accelerator pump and primes the en-
gine).
 Return the control handle to fast idle position.
2. Turn key switch to START position and hold until
engine starts. Do not hold in START position for more
than ten seconds. In colder weather more priming may
be necessary; however, too much priming may flood
engine.
 Repeat priming one time if the engine does not start
on the first attempt. Do not over prime the engine or
the engine will become flooded with fuel.
Note When starting engine for the first time after off-
season storage, always allow the engine to idle for one
minute to allow the engine to fill with water.
Securely tie the boat to the dock whenever
advancing the engine above 1000 RPM since the
boat will drift forward.
3. As soon as engine starts:
 Release key to the ON or RUN position.
 Move control handle to the fast idle position to warm
up engine. Do not exceed 1000 RPM.
4. If the engine floods with fuel when starting the boat
in the water, clear the flooded condition as follows:
 Disengage shift control. Move handle to full throttle
position.
 Turn key switch to the START position.
 Immediately move the control handle to the idle
position when the engine starts.
OPERATION
BEFORE STARTING _________________
Familiarize yourself with the operation of the remote
control supplied with your boat, then proceed as follows:
To prevent a possible explosion, operate the
blower for at least five (5) minutes or as
recommended by the boat manufacturer before
starting the engine. If the engine compartment
is not equipped with a blower, open the engine
cover or hatch prior to starting to allow any
gasoline fumes that may be present to disperse.
Leave hatch open until after the engine is
running.
1. Operate the boats bilge (inside bottom of the boat)
blower for at least 5 minutes or as recommended by the
boat manufacturer. Frequently check boats bilge area
for gasoline fumes.
2. Check the bilge for excessive water accumulation.
Always keep the bilge (inside bottom of the boat) clean
and dry. Water depth in the bilge should be kept below the
flywheel housing. If water accumulation is unavoidable,
install a bilge pump with an automatic control switch.
Note The water level in the boats bilge will increase
when the boat is operated at a high incline before
planing speed is reached. Excessive water in the bilge
can cause engine damage.
3. Check engine crankcase oil level.
4. Ensure the bowl bearing has sufficient oil to allow
the Power Jet to be run out of the water. Refer to the
Maintenance section to fill the bowl bearing cavity with
lubricant.
When using a flushing adapter, stay away from
the moving drive belt and pulleys or severe
injury can result.
Note Do not start engine out of water unless using a
flushing adapter. Always turn water on before starting
engine. Control water pressure as full water pressure
may cause damage to engine. The engine will overheat
if operated without cooling water.

15
STARTING WARM ENGINE ___________
1. Move control handle to the neutral detent position.
2. Turn key switch to START position and hold until
engine starts, but do not hold in start position for more
than ten seconds. If engine does not start, let go
momentarily, then try again.
3. As soon as engine starts, release key to the ON or
RUN position.
Note Never turn key to START position when engine
is running.
HOW TO SHIFT AND CONTROL SPEED _
Note If your boat is equipped with a non-VOLVO
PENTA remote control system, ask your dealer how to
properly operate it.
Note This Power Jet powered boat produces thrust
at all times the engine is running. In neutral the thrust
is balanced between forward and reverse by the
position of the reverse gate.
Carefully check function of all control and
engine systems before leaving the dock.
Do not attempt to shift from forward to reverse
at high engine speeds. The reverse gate will not
be able to enter or change the Power Jet stream
at high engine speeds which will prevent
reverse thrust being used to stop the boat.
1. Move control handle to the neutral detent (idle)
position. This will engage neutral start switch and allow
engine to start. Check in front and behind boat for
people or obstructions before shifting.
2. To go FORWARD, actuate the neutral lock
mechanism and move the shift handle forward. Throttle
movement will begin after the reverse gate is fully
retracted out of the Power Jet water stream.
3. To go in REVERSE, actuate the neutral lock
mechanism and move the shift handle rearward.
Throttle movement will begin after reverse gate is fully
down, fully diverting the Power Jet water stream in the
reverse position.
Note Do not shift when engine speed is above 1000
RPM.
Do not shift from forward to reverse when boat
is planing or passengers could be thrown
overboard. Always allow the engine to return to
idle when shifting from forward to reverse.
4. To go from FORWARD to REVERSE, or
REVERSE to FORWARD, always pause at NEUTRAL
and allow engine speed to slow down to under 1000
RPM.
5. After shifting is completed, continue to move the
control handle in the desired direction to increase
speed.
OPERATION

16
Whenever the boat is operated, be aware of
changes in shift system operation. A sudden
increase in shift effort at the remote control
handle, or other abnormal operation, indicates a
possible problem in the shift system. If this
occurs, the following precautions must be
taken:
 With engine running and boat securely tied to the
dock, shift drive into forward and reverse to ensure
there is directional control.
 When docking the boat, all docking maneuvers
must be performed at slow speed. Pay special attention
to other boaters. Passengers should be informed of
potential problems and precautions taken.
If you suspect there is a problem shifting, see your
VOLVO PENTA dealer as soon as possible for proper
diagnosis and required service or adjustment.
Continued operation could result in damage to boat, and
loss of shift and throttle control that could result in
personal injury.
STOPPING ENGINE __________________
1. Move control handle to the NEUTRAL position.
2. Turn ignition key to the OFF position.
Note Do not stop engine at speeds above idle or
speed up engine while turning off ignition. Engine
damage could result.
ENGINE BREAK-IN __________________
Note Failure to follow the Engine Break-In procedure
can result in serious engine damage.
All VOLVO PENTA engines have been run for a short
period of time as a final test at the factory. You must
follow the Engine Break-In procedure during the first 20
hours of operation to ensure maximum performance
and longest engine life.
Note To ensure proper lubrication during the break-in
period, do not remove factory break-in oil until after the
20-hour break-in is completed.
During the break-in period, be particularly observant
during the initial running of the engine, as follows:
Check engine oil level frequently. Maintain oil level in
the safe range, between the add and full marks on
dipstick. Somewhat higher oil consumption is normal
during the break-in period until piston rings have seated.
Note If you have a problem getting a good oil level
reading on the dipstick, rotate dipstick 180° in tube.
When adding motor oil, refer to Motor Oil, in Fuel and
Lubrication Requirements section.
Watch the oil pressure gauge. If the indicator
fluctuates whenever the boat attitude (e.g., turning,
climbing on plane etc.) is changed, it may be that the oil
pickup screen is not covered with oil. Check crankcase
dipstick. Add oil to the crankcase if required. DO NOT
OVERFILL. If oil level is correct and condition still
exists, see your dealer for possible gauge or oil pump
malfunction.
Note Oil pressure will rise as RPM increases, and
fall as RPM decreases. In addition, cold oil will generally
show higher oil pressure for any specific RPM than hot
oil. Both of these conditions reflect normal engine
operation.
Watch the engine temperature indicator to be sure
there is proper water circulation.
Note Failure to follow the break-in procedure will
void the warranty.
First Two Hours
For the first thirty (30) minutes of operation, operate
the engine at a fast idle (above 1500 RPM but less than
2500 RPM). During the next thirty (30) minutes of
operation keep the engine below 3000 RPM. During the
next thirty (30) minutes of operation keep the engine
below 3500 RPM. In the last thirty (30) minute interval of
the first two hours, keep the engine below 4000 RPM.
Do not allow the engine to stay at any constant RPM for
longer than five (5) minutes at a time during the break-in
period - keep varying engine speeds during the first two
hours of operation.
OPERATION

17
After the engine has reached operating temperature,
momentarily reduce engine speed, then increase
engine speed, to assist the break-in of rings and
bearings. If possible, maintain planing attitude to avoid
excessive engine load.
Note DO NOT RUN ENGINE AT ANY CONSTANT
RPM FOR OVER FIVE (5) MINUTES OF TIME FOR
THIS INITIAL TWO HOURS OF BREAK-IN.
Next Eight Hours
During the next eight hours, continue to operate at
approximately three-fourths (¾) throttle or less
(minimum planing speed). Occasionally reduce throttle
to idle speed for a cooling period. During this eight
hours of operation it is permissible to operate at full
throttle for periods of less than two minutes.
DO NOT RUN ENGINE AT A CONSTANT RPM FOR
PROLONGED PERIODS OF TIME DURING THE
BREAK-IN PERIOD.
Final Ten Hours
During the final ten hours of break-in, it is permissible
to operate at full throttle for five to ten minutes at a time.
After warming engine to operating temperature,
momentarily reduce, then increase, engine speed.
Occasionally reduce engine speed to idle to provide
cooling periods.
DO NOT RUN ENGINE AT A CONSTANT RPM FOR
PROLONGED PERIODS OF TIME DURING THE
BREAK-IN PERIOD.
At the end of the break-in period (20 hours), remove
motor oil and replace the oil filter. Fill crankcase with
recommended motor oil.
OPERATION AFTER BREAK-IN ________
After break-in, the engine can be operated at any RPM
from idle to full throttle; however, cruising at 3600 RPM
or less saves fuel, reduces noise, and prolongs engine
life.
Be sure to check the oil level frequently during the first
50 hours of operation, since the oil consumption will be
high until the piston rings are properly seated.
DETERMINING THE PROPER TRIM ____
The effect of bow-up and bow-down positions will be
similar for most boats. The bow position that is best for
your operating conditions can be adjusted to give the
desired bow-up and bow-down positions. Only adjust
and test the trim plate (the adjustable plate located
behind the intake opening) when the boat is loaded as
you would normally operate the boat. (Full fuel, people
and movable cargo that are normal for your operating
conditions.) The boat may operate differently between
its fully loaded condition and its lightly loaded condition.
The boat is properly trimmed when the trim angle
provides the best boat performance for your particular
operating conditions.
Make test runs at slower speeds and various trim plate
positions to see the effect of trimming. Note the time it
takes for the boat to plane. Watch the speedometer
readings and the ride action of the boat.
PUMPING BILGE ____________________
Frequently check bilge for leaking fluids. Find the
cause and correct it immediately. Virtually all federal,
state, and local governments prohibit the discharge of
oily waste into navigable waters or on the land. Always
properly dispose of oily waste in an approved manner.
SALT WATER OPERATION ___________
Your VOLVO PENTA Power Jet is built for operation
in either fresh or salt water. Fresh water internal flushing
is recommended after use in polluted or salt water.
If freezing temperatures are expected, remove the
boat from the water and drain the cooling system and
Power Jet bowl (following Off Season Storage
Preparations in Specifications and Maintenance
section).
If possible, remove the boat from the water, rinse with
fresh water, dry, and spray the entire exterior and
interior of the Power Jet with anticorrosion spray,
following the directions on the container.
OPERATION

18
SHALLOW WATER OPERATION _______
Your VOLVO PENTA Power Jet pumps high
volumes of water, which creates considerable suction
at the intake grill. The Power Jet can be operated in
very shallow water without harming the unit if
precautions are taken.
When passing through shallow water, such as
over sand bars, debris, etc., keep moving the
steering wheel a half turn from side to side to
prevent the steering nozzle from seizing
causing loss of steering control. Sand and
debris pulled into the Power Jet can cause the
steering nozzle pivot points to fill with sand
and debris causing the steering nozzle to seize.
Note NEVER ATTEMPT TO PLANE THE BOAT
OR EXCEED 1000 RPM IN SHALLOW WATER OR
THE POWER JET MAY BE DAMAGED.
 When operating in shallow water at slower
speeds, sudden increases in engine speed
should be avoided to prevent sand and gravel
from being drawn up into the unit.
 When traveling over shallow water, sharp turns
should be avoided and speed should be main-
tained to minimize the draft of the boat.
 When traveling over small patches of debris,
reduce engine speed momentarily to reduce the
suction at the intake.
 Do not operate at high speed in shallow water.
 If starting up in shallow water, proceed to deep
water at slow speed before accelerating to high
speed.
CLEANING OUT A CLOGGED INTAKE __
While operating the Power Jet you may notice
decreased thrust and, at the same time, increased
engine speed. This condition may indicate a clogged
intake that must be cleared to restore performance.
Ensure the keys are removed from all starting
locations before attempting to clear debris from
the intake or through the clean out opening, or
you can be injured. Perform the clean out
procedure while the boat is on the trailer or in
water shallow enough to allow you to safely
stand on the bottom. Do not attempt to clear the
Power Jet in deep water as you could be thrown
overboard. If necessary, have the boat towed to
shallow water before attempting to clear the
Power Jet of debris.
11.Loosen the clean out cover hold down screws,
remove the clean out cover A.
22. Remove any debris in either the intake grate or in
the intake housing around the shaft and in the impeller.
3. Place the clean out cover Aback into place and
lower into the housing. Tighten the cleanout cover
screws.
