SECTION 1 - SERVICE SAFETY
Inadequate knowledge of safe shop practices can result in severe injury or
death. Review general safety procedures and specific safety information
provided for each procedure prior to beginning any repairs.
INTRODUCTION
Raider outboards is required to comply with special E P A regulations and
standards to ensure your military products are safe and reliable. As the
military technician, it is your responsibility to keep these products safe when
performing normal repair and maintenance operations.
It is not possible to foresee all safety hazards which may occur or to include
all the knowledge of an experienced technician in a single service manual.
Therefore, it is assumed those using this manual have a working knowledge
of 2-cycle outboard engines and the proper technical training for servicing.
Raider outboards is considered a Commercial Off The Shelf (COTS) outboard
engine. The engine comes from a family of engines: Mercury, Nissan and
Tohatsu.
This section discusses safe shop practices and general safety concerns
relevant to the operations performed throughout this manual. Read this
section carefully and follow all safety statements in this manual as they
pertain to the procedures at hand. Remember, always use common sense
when servicing outboard engines!
Raider supports three manuals for Generation II Outboards:
Owner/Operators Gen II Manual; R40-ES-001-16-1;
Parts and Assembly Gen II Manual: R40-ES-001-16-2 which has all part
numbers and assembly information; and
Raider Gen II Service Manual R40-ES-001-16-3 that provides complete
information to repair the Raider 40 Generation II outboard motor.

SAFETY PRECAUTIONS
Raider Outboard Engines
Never disable the neutral switch start-in-gear prevention
system. Always test the neutral switch and emergency stop
switch before returning an engine to the user.
Lifting devices and hardware must be of suitable capacity for
the weight of the outboard engine. Be aware the engine may
swing outward when lifted.
The Raider engine stand must be in good condition; Raider
engine must be mounted properly to prevent unexpected
shifting.
Engine covers (cowling) are guards to prevent personal
contact with the spinning flywheel and high voltage
components such as spark plugs and coils. Never wear
jewelry or loose clothing near a running engine. Keep hands,
arms and hair away from the flywheel. Never touch electrical
components when the engine is running.
Two people working on a running engine must use extreme
caution and be aware of one another. Never attempt to start
an engine or operate any controls before signaling your
partner.
To prevent accidental startup during operations which may
cause the flywheel to turn, always perform the following steps:
1. Insure battery is disconnected or removed.
2. Disable the engine ignition system.
3. Shift engine to NEUTRAL and verify propeller shaft is
not in gear.
Rotating propellers are not equipped with guards and can
cause severe injury or dismemberment. Always stay clear of
rotating propellers and make sure there is no possibility of
engine startup before removing or installing a propeller. The
propeller nut must always be tightened to torque specification
prior to starting the engine.
7
Raider Start Button
Additional Safety Precautions
Avoid running the engine at high RPM. Engine speed can easily
increase to excessive RPM when under a no load condition. To
avoid engine damage during testing, always use the correct test
propeller and keep engine speed below 2000 RPM.
Run engines only in well ventilated areas to prevent exposure to
Carbon Monoxide (CO) gas. Direct and prolonged exposure to
CO will cause brain damage or death.
Always wear eye protection, protective clothing, gloves and use
other applicable safety equipment when work activities present
the risk of personal injury.
Batteries
Never leave batteries in Raider outboards for long periods of
time. Always unplug when not in use.
Place batteries on “maintainer” when not in use.
Never use “fast” charge on batteries that are used on vehicles.
These batteries are sealed lithium Iron; 270 Cranking Amps.
Prior to Mission – place on maintainer for 6 hours
Battery can be left in RAMZ for up to three months.
Disconnect internal connection when placed in RAMZ.
If detection of heat in battery remove and discard.
Make sure battery looks in good condition.
8
Hazardous Materials
Gasoline vapors are highly flammable and can cause an
explosion. Never smoke or allow sparks or flames nearby
when handling fuel Always store gasoline in a shaded, well
ventilated area in an approved safety container.
Heavy Fuels that can be burned in the Raider 40 have
harmful fumes that must be considered hazardous. Wear
masks.
Ventilate all fumes as soon as detected. Be aware that
appliance pilot lights, such as those in furnaces and water
heaters, can ignite gasoline vapors and cause explosion.
Never use gasoline as a cleaner, and always clean up fuel
spills immediately and properly dispose of rags in an
approved safety container.
Read and follow the safety labels on products used around
the shop. Adhesives, lubricants, solvents, and fuel additives
are usually poisonous and flammable. Store and dispose of
these products properly.
Shop Environment
Make sure the shop and your work area are properly
ventilated.
Shops must be equipped with the proper tools and safety
equipment such as fire extinguisher, eye flushing device, and
first aid kit.
Keep the shop clean and free of clutter. Clean up spills on
the floor as soon as possible to prevent someone from
slipping.
WORKMANSHIP STANDARDS
1. Avoid damage to the mating surfaces of crankcase and
cylinder assembly. Do not use a sharp metal scraper to
clean these areas.
2. Replace gaskets, 0-rings, seals, cotter pins, lock nuts, and
spring pins when removed during repair operations.
3. Use only genuine factory replacement parts and
accessories.
4. Use recommended special tools when specific repairs
require them.
5. Calibrate measurement tools and test equipment on a
regular basis.
6. Clean all metal parts with solvent before inspection and
assembly operations.
7. Use penetrating solvents when necessary to remove
9
rusted or seized
hardware.
8. Keep all removed parts separated for ease of
identification during assembly.
9. Locate alignment marks on components being
disassembled. If marks are not present and should
be, scribe or match mark them yourself to ensure the
pieces are assembled properly.
10. Follow torque sequences and specifications where
they apply. First, tighten each bolt in the specified
sequence. Use the same sequence to torque each
bolt to final specification. Special torque specifications
are listed at the beginning of each section. Standard
torque specifications for common fasteners are listed
in Section 3.
11. Use lubricant when assembling seals to prevent
damage to the seal lips. Make sure seal lips are facing
the correct direction.
12. Use the correct type and amount of sealing compound
on metal to metal surfaces.
13. When using compressed air to clean or dry parts,
make sure air supply is regulated not to exceed 25 psi
[172 kPa /1.76 kg/cm'].
14. Replace missing or damaged safety labels on the
engine before returning it to the user.
NOTE: Throughout this manual
“genuine” oil if used. This oil is the
Raider Outboard two-stroke oil;
however, any TC-W3 approved oil can
be substituted and used.
10
TEST TANK GUIDELINES
When properly setup, test tanks provide a safe and controlled environment in which to
perform outboard engine adjustment and testing procedures. Test tanks must be
setup to the minimum dimensions shown. If multiple engines will be installed in the
tank, secure partition plate (1) so that the minimum dimensions are maintained for each
outboard engine installed. In addition, adhere to the following guidelines to prevent
engine damage:
• Continuous usage raises the water temperature in the tank which can lead to engine
seizure. Make sure water temperature in the tank does not exceed 77°F [25°C].
• Repeated use introduces carbon into the water which can adhere to the engine cooling
system and degrade its ability to cool the engine. Always replace dirty tank water at regular
intervals with clean, fresh water.
• Exhaust gases produced during engine operation can collect around the engine, causing
suction into the carburetors and affecting engine performance. To prevent this condition,
install forced ventilation equipment (2) to move gases away from the engine and work area.
• Water may splash out of the tank during testing. Maintain water level (3) in the tank as
illustrated.
• Keep transom board (4) at an approximately 75° angle to the tank bottom to ensure near
vertical engine position.
• Test Tank Drawing:
11
SECTION 2 – General Information
General Precautions
Before performing any service work on the outboard engine, read and understand Section 1 - Service
Safety.
Use only genuine factory replacement parts with equivalent characteristics such as type, material,
and strength. Failure to do so may result in product malfunction and injury to the operator or
passengers.
Follow the Standard Torque Values chart. When a special torque value for a certain fastener is not
listed in the Special Torque Values chart at the beginning of each section tighten using the Standard
Torque Values chart.
Rather than just repairing a bad part, use repair kits and overhaul kits when applicable to ensure
complete and efficient repair of the complete component. Wear not readily noticed on other parts can
lead to malfunction soon after the r epair .
When indicated in a procedure, use manufacturer special tools. In some cases, the use of substitute tools
will damage the part.
When using compressed air to clean or dry parts, make sure air supply is regulated not to exceed 25 psi
[172 kPa / 1.76 kg/cm'].

2.
3.
4.
Use full throttle to quickly accelerate boat onto plane; then immediately reduce throttle to
3/4 and maintain this speed.
At intervals, run engine at ¾ throttle for 1-10 minutes then return to ½ throttle for a cooling period.
Vary engine speed every 15 minutes.
Check for water discharge from cooling water check ports.
Next Eight Hours (2 to 1 0 Hours)
1. Run engine at 3/4 throttle.
2. For short periods of time, run engine at full throttle and then reduce speed back to 3/4
throttle. As this part of the break-in period progresses, open to full throttle for longer
and longer periods of time, but never longer than 5 minutes.
3. Vary engine speed every 15 minutes.
DO NOT exceed the Full Throttle RPM Range of the engine. See Engine Specifications in this
section.
After Break-in Re-torque cylinder head bolts to specification after engine has been run and
cylinder head has cooled to the touch.
Empty fuel tank and replenish with a 50:1 gasoline/oil mixture.

5. Fuel Plate
6. Crankcase
41
Fuel Pump [3] above
The fuel pump is integral with the carburetor and mounted on the side of the
crankcase and contains one or more internal diaphragms (1). The diaphragms move
in response to changing crankcase pressures (2) which draws fuel in (3) and pumps
fuel out (4). A series of check valves (5) in the pump ensure that fuel moves only in one
direction.
Carburetor [1] above
The carburetor is used a pilot system and works in conjunction with the fuel plate to
deliver an atomized fuel mixture to the engine for combustion under varying operating
conditions.
Recirculation
Recirculation hoses at the inlet manifold and crankcase re-circulate unburned fuel for
engine consumption.
Fuel Bladder Connection
Raider provides a 10 ft. fuel hose from the bladder to the Raider 40. The hose comes
with a connector that goes into the fuel bladder to insure proper connection.

needs to be done in an appropriate machine shop. Light scuffing or burn does not require boring for
removal. Use water-resistant #320 sand paper to remove the damages, the use #400 and #600 to
finish.
1. Visually inspect all internal components. lnspect for unusual wear patterns,
heat-related discoloration of bearings, broken parts, and scuffing or damage
to aluminum parts.
2. Inspect the intake manifold and reed valves. See intake Manifold – Section 3.
