1. Your Raider 40 Outboard Motor
a. Limited Warranty
This Raider product is fully guaranteed against defective materials and workmanship for
the period on one year from date on DD-250 form. The limited warranty will not apply to
normal wear and tear of parts, adjustments, tune-ups, or to any damage caused, but not
limited to careless use.
Raider has taken every advantage using non-corrosive materials, high quality and high
reliable parts. This multi-fuel, submersible outboard has been built for ruggedness and
durability to meet war fighter’s needs. After missions the motor should be washed with
soap and water and let dry. Fuel should be run out prior to storage.
The limited warranty does not cover maintenance items. The following items are a few
examples not covered by the limited warranty: spark plugs, Anode, Propeller, Fuel filter,
Oil filter, Starter rope, Shear-pin, Rubber goods, water pump impeller, oil seal, vinyl tub-
ing, and battery.
The limited warranty will not cover the boat the product is mounted on, trailer, equip-
ment, or accessories associated with the product.
b. Serial Number
The serial number is located on the engine block-near heads.
c. Safety/Danger/Warnings/Cautions
Before operating the Raider outboard motor, be sure to thoroughly read and understand
this Users manual and follow all of the instructions shown. Of particular importance in-
formation preceded by the words or symbols draw attention to safety issues. This man-
ual contains information that can help prevent personal injury and damage to equipment.
Understand the following symbols before proceeding:
All motors with electric start will start in gear. User has responsibility to insure Raider is
in neutral before starting. Operator assumes responsibility for this operation.
Battery

up fuel lines. Squeeze fuel bulb to get fuel into motor. Insure bat-
tery is connected. Press start button –or pull start. Dewatering:
slide lever located on left side of motor to rear of engine; pull 8

g. Fuel Induction System-Multi-fuel
Multi-fuel Fuel Induction System (FIS) (Operation)
The FIS is styled after a conventional carburetor; the difference is the shape of the air
inlet; shaped to speed up the air which intersects the fuel and between harmonic vibra-
tion of the metering rod the molecules break down to a fine mist. The figure below
shows atomization of the engine fuels prior to entering the combustion chamber.

2. Raider Installation___________________________________________________
a. Handling Engine
The Raider was designed to be carried by a grab rail unit. This
allows the outboard to be moved through submarine hatches and
small areas. The grab rail will protect engine from getting damaged. Be
aware of the sharp propeller when lifting through submarine hatches.
To move engine around shop area, use the Raider outboard stand, supplied
with the delivered engines, that supports engine by transom mount.
b. Installation of single Engine
The Raider has been designed to be released from submarines and air dropped. This in-
stallation will discuss a typical installation –no special operations installation.
Position the outboard engine at the exact center of the stern and mount it against the Rub-
ber Inflatable Boat pad or plate. It is important to keep it centered as much as possible,
Tighten clamp screws by hand DO NOT use tools to tighten clamp screws. Retighten en-
gine clamps after 15 minutes of operation.
WARNING
Most Rubber Inflatable Boats are rated and certified in terms of
their maximum horsepower on the transom. This information is
shown on the boat’s certification plate. Do not equip your RIB with
an outboard that exceeds this limit.
Do not operate the engine until it has been securely mounted on
the boat in accordance with the instructions. Attach safety wire to
boat to avoid losing the motor overboard.

c. Installation of Twin Engines
When installing two outboard engines, be sure to keep an interval of 470 to 600 mm (18 to
26 inches) between the two engines. Both outboard engines should be at the exact center
of the stern and mount it against the Rubber Inflatable Boat pad or plate. It is important to
keep it centered as much as possible, after centering on transom tighten clamp screws of
both motors by hand. The attachment of a single steering unit for dual mount assembly can
be quickly placed on dual motors for control and a cable inserted from one engine to the op-
posite for single power to both outboards.
d. Installation of Safety Wire
To prevent loss of engine (engines) overboard, attach engine retention
cable that is attached to the Raider outboard to the boat.
e. Transom Height

18 to 26 inches apart
CAUTION
Overheating may occur if Anti-
ventilation plate is at higher level
than the boat as a lack of cooling
water.
Raider motors can be ordered with
fastening holes on each side of the
motor for multiple motor usage.
This allows all motors to be used in
a dual configuration.

Raider Operators Manual R40ES-001-15-1

The Raider has been designed to have the anti-ventilation plate at a level 10 to 30 mm
(0.4 to 1.2 inches) below the bottom of the boat as shown above. Be sure the anti-
ventilation plate of the Rader outboard is below the water surface when running with
wide open throttle.
f. Propeller
A propeller must be selected so that the engine rpm measured at wide open throttle while
cruising is within the maximum operating range. In the Raider that range is between 5200
and 5800 rpm.

To ensure optimum performance, the propeller should match the boat type and its load.

Battery
The Raider 40 can be delivered with electric start. It is important to remember the
electric start is a secondary method of starting the outboard. The primary start
is the manual pull start.
The battery is lithium iron and has been sealed. If you notice any issues with the
battery, like overheating, remove and replace the battery. If the battery fails to
start it will recharge after the Raider is in operation. Note: prior to mission the battery
should be placed on the “maintainer” which will indicate if battery is useable or not.
The battery should never be placed on a “fast” charger. The Raider battery has a
Connector compatible with small maintainers. These are available at any Battery/Bulbs
Commercial sales houses. The connectors are made to only go on one way.
When battery not in use –UNPLUG. Acharge can be held for 90 days if packaged in a
RAMZ package.
Replacing the propeller.
A worn or bent propeller will affect engine
performance and may over time cause en-
gine trouble.
1. Pull out the split pin and remove the pro-
peller nut and washer,
2. Remove the propeller by pulling towards
you.
3. Apply grease to the propeller shaft before
mounting the new propeller.
4. Fit the washer, securely tighten the nut
and insert the split pin.

3. Raider Running
a. Fuels (Multi-fuel)
The Raider can run on jet fuels (JP-5/8), diesel fuel, kerosene, gasoline or gasohol/ethanol.
There are four processes (1. Turn top lever to green; 2) Turn up Secondary to green; 3) turn
counter clock valve –open the entire way; 4) lift knob up, insert lock to completed running
on heavy fuels. If you switch from one fuel to another fuel the Raider engine will operate dur-
ing transition. When using the twin engine configuration it is recommended similar fuels are
used. Additives must be added to fuel prior to missions that use JP-5/8 heavy fuels.
b. Raider Break in
10 Hours. The Raider has provided the break in at the factory. The most critical time in the life of the
Raider engine is the first 10 hours of operation. Correct operation during this break-in period will pro-
long the life of the engine and ensure optimum performance. The procedures we follow are shown
below.

Battery Care and Maintenance
1. Battery should be un-
installed when not in use
and placed on charger.
2. Battery is pluggable into
connector
If battery goes “dead” Raider will
recharge –use pull starter to start
Primer: This is used to push fuel
into the Fuel Induction System
