SerialNumberLocation: Found on top of block –three digits
The Raider R50-001 is a specially manufactured outboard motor for the military for use on Rubber
Inflatable Boats. This motor can be submerged for long periods of time and quickly restarted; operated
on multiple fuels; contains electric start with the battery located under the cowling.
We would like to point out that usage can only be assured on condition that this manual is read through in
its entirety and the maintenance routines described later in this manual are followed carefully. Should
difficulty arise with the engine, please follow the troubleshooting procedures listed at the end of this
manual. For any issues , contact www.raideroutboards.com.
NOTICE: DANGER/WARNING/CAUTION/Note
Before operating your outboard motor, be sure to thoroughly read and understand this Owner's
Manual and follow all of the instructions shown. Of particular importance is information preceded by
the words "DANGER," "WARNING," "CAUTION," and "Note." Always pay special attention to such
information toensuresaferand trouble-free operation atall times.
YOUR RAIDER OUTBOARD MOTOR
OWNER REGISTRATION AND IDENTIFICATION
This Raider outboard has been purchased by the U.S. Military. Every motor has been delivered under
Form DD-250 which contains individual Serial Nos. www.raideroutboards.com has a record of every
motor delivered.
PRE-DELIVERY CHECK
Insure all physical aspects of the Raider Outboard looks undamaged.
LimitedWarranty
Raider Outboards are fully guaranteed against defective materials and workmanship for the period
from the date of the Form DD-250 for one year. The limited warranty will not apply to the normal wear
and tear of parts, adjustments, tune-ups, orto anydamage caused by:
l) Use or operation NOT conforming to the instructions described in this owner's manual,
2) Parachutes not opening
3) Improper dewatering –Raider must be flushed with fresh water; washed down with soap/water.
4) Damage of an accidents, collisions, contact with foreign materials, or submersion without cleaning.
5) Growth of marine organisms on motor surfaces that exceeds Submersibility times
6) Any other careless use or operation issues (Battery unplugged when not in use)

The limited warranty does not cover maintenance items. The following items aresomeexamplesnot
covered by the limited warranty.
Spark pl ugs, anode, trim-tub, propeller , fuel filter , oil filter . Carbon brush. Starter rope, shear-pin ,
split-pin, bolt/nut · washer, wire cable. Rubber goods: pump impeller. Oil seal, "O" -ring, fuel pipe,
primer bulb, etc., vinyl tube .
The limited warranty will cover only your Raider Outboard and will not cover the boat/RIB the Raider is
mounted on, the trailer, equipment, or accessories associated with the product.
EMERGENCY STOP SWITCH
The stop switch will cut off the engine when the stop switch line is pulled out. This line can be attached
to the body of the operator, effectively preventing injuries from the propeller in case he/she falls
overboard.
We highly r ecommend use of stop switch line because it can save the life of the operator if
something bad happens . However, we would als o like to point out the drawbacks of the switch. Accidental
activation of the switch (such as the line being pulled out in heavy seas ) could cause passengers to lose their
balance and even fall overboard, or it could result in loss of power in heavy seas, strong currents, or high
winds. Loss of control while mooring is another potential hazard. To prevent such hazardous situations, the
500 mm line is coiled and can be extended toa full 1,300mm.
WARNINGS
As the operator/driver of the boat, you are responsible for the safety of those aboard and those in other
crafts around yours. Therefore you should possess thorough knowledge of correct operation of the
Rubber Inflatable Boat (Wing/Zodiac), its accessories, and the Raider engine. To learn about the correct
operation and maintenance of the engine, please read through this manual carefully.
It is very difficult for a soldier standing or floating in the water to take evasive action should he or she see
a power boat heading in his/her direction, even at a slow speed. Therefore, when your boat is in the
immediate vicinity of people in the water to be picked up care should be used. A Safety Jet option (jet
pump) from Raider is available and especially useful for training purposes.
SERIOUS INJURY IS LIKELY IF A PERSON IN THE WATER MAKES CONTACT WITH A MOVING BOAT, GEAR
HOUSING, PROPELLER, OR ANY SOLID DEVICE RIGIDLY ATTACHED TO A BOAT OR GEAR HOUSING.
Prior to any mission some individual must be assigned to perform all safety checks and to ensure that all
lubrication and maintenance instructions are complied with for safe operation. Periodic maintenance
should be performed. Correct periodic maintenance and good careof this outboard engine will lessen the
chanceof problems and keepoverall performance of missions successful.
A CAU TIO N
Fail u re to observe could result in mi nor personal i njury or product or
property damage.

SERVICING, REPLACEMENT PARTS & LUBRICANTS
Only qualified personnel should perform maintenance on the Raider. Training classes can be given or
questions answered by contacting www.raideroutboards.com. Be sure to use genuine Raider parts and
genuine Raider lubricants or recommended lubricants. 50:1 mix should be synthetic TC-W3 2-cycle oil.
MAINTENANCE
Periodic inspection at the prescribed intervals is critical. The Raider motors will be subjected to drops,
submersion and other abuse typical outboards will never receive. The most critical maintenance, after
missions, is to wash down the motor with water and dry. When in salt water it is important to run fresh
water through the system. For long period of time storage a fogging spray can be used. Trouble free
operation cannot be expended unless the engine receives adequate periodic maintenance. If
maintenance isperformed periodically, it isnot likely that acostly overhaul will everbe required.
A maintenance program is outlined later in this User’s Manual.
SUBMERSIBLE - DEWATERING INSTRUCTIONS
Instructions on how to dewater the Raider 50 is located on the top of the cowling. The steps to
dewater after submersion are as follows:
1. Initiate dewatering valve. This opens valve that releases the water trapped between the
pistons and the heads.
2. Pull rope starter slowly 8 –10 times. The pistons will displace water out of engine.
3. Keeping dewatering valve open; press “start” button. The pistons displace final water and
engine begins to start.
4. If pull start is used, close valve, pull until starts. Primer valve can be pushed to assist
starting.
5. Close dewatering valve. Engine starts.
6. If operator detects water in Fuel system; press dewatering valve all the way in, press
rubber bulb on fuel line three times to eliminate fuel which is replaced by new fuel.
7. Spark plugs rarely need changing; they are designed to operate in wet environment.
EPA LABEL
A label has been applied indicating the Raider 50 does not comply with EPA standards due to
Burning JP-5/JP-8 fuels.
USERS
Raider outboards are designed and built exclusively for the military under National Security
Exemption.
MULTIPLE FUELS
Raider 50 has been designed to operate with multiple fuels: JP-5/JP-8; jet A; kerosene; diesel and bio-
fuels as secondary fuels. Gasoline (minimum 87 octane) is primary fuel. To run heavy fuels each Fuel
Induction System (FIS) has two valves that must be turned to open position. When not using heavy
fuels close valves.

3. RAIDER INSTALLATION ON RUBBER INFLATABLE BOATS
(RIBS)
4.7 RIB’s may have weight/horsepower limitations –
Raider 40 weight is 148 pounds for single Outboard –without Safety Jet Drive
Raider 50 weight is 178 pounds for single Outboard –without Safety Jet Drive
Check transom tag on RIB prior to installation. Install motor(s) as close to center as possible.
3.1 Installation - Single Raider
Position the outboard engine at the exact center of the stem (Fig. I ) of RIB.
3.2 Dual Raiders Configuration
Position the outboard engines 470- 660mm (18.5 - 26.0 in.) apart, measured from an
imagined center line of each engine, in the exact center of the stem. (Fig. 2). After centering
the engines, insure the control rod reaches both engines. Twin engine configurations have an
extended motor rod where the control arm attaches. Remove cowling and insert dual-control
throttle cable.
Every Raider can be made to become “dual” operated. Order the optional kit which contains
Cable; connecting rod; and motor adapter. The connecting rod controls both Raiders; the
throttle cable quickly integrates both fuel controls. Either tiller can be used.
Most Rubber Inflatable Boats are rated and certifi ed in terms of thei r
maxi mum horsepower and weight of outboard, and thi s is s hown on
the boat' s certifi cation plate. Do not equi p your RIB wi th an outboard
that exceeds this limit.
Do not operate the engi ne un til it has been securel y mounted on the
boat in accordance with th e instructions.

10
3-3 RIB TRANSOM HEIGHT
Install the engine with the Anti-ventilation Plate at a level l0 - 30mm below the bottom of the
boat (Fig. 3).
10-30mm
(0 .4 -1.2 inches . )
(Fig.3)
3-4 Transom Matching with RAIDER 50.
Be sure that the anti-ventilation plate of the outboard is below the water surface whenrunning
withwideopenthrottle. If the Raider pushes water into the RIB; raise the motor on the transom
by adding a shim on top of transom to achieve proper Raider motor height.
Note: If the height difference exceeds 10 – 30 mm engine power performance is likely
to be reduced as a result of increased water resistance to the gear case assembly.
3.5 Attaching theStern Bracket
Both Zodiac and Wing inflatable’s come with bracket attached. The Raider is a long shaft (20 inches)
and should attach simply by centering the Raider 50 in the center and tighten Raider clamps. For dual
Raiders position motors as described above to allow connecting rod to be attached.
A CAUTION
Overheati ng may occur if t he Anti -venti l ati on Pl ate Is at a level higher
than the bottom of the RIB, as a result o f ai r sucki ng rather than water.

11
3.6 Propeller Selection
The propeller supplied with the Raider is an “all around” propeller. Whatever propeller you ultimately
decide to use must be selected so that the engine rpm measured at wide open throttle while cruising is
within the recommended range between 5000 to 5700 rpm. The Raider 50 can be made faster or
push more weight by changing propellers.
A Safety Jet option is available that encloses the propeller for safety purposes such as training or
operating in a heavy debris area.
3.7 Cowling rear latching
When removing cowling/top cover unlatch as shown; bring cowling forward to clear the pull start.
When returning cowling to operating position; first clear pull start; center the front over the extended
edge; then place cover in place. This is a tight fit, you may have to push cowling toward rear and latch
the cowling to the base Raider.
3-8 Battery
The battery is located under the cowling; it is a sealed lithium iron battery providing 270 Cranking
Amps. The battery is held by a holder with a bottom cut out; the battery case has an extended case
that fits into the cut out (slot). To remove unscrew single screw; remove connector from Raider; and
remove battery. To reinstall; place battery in holder; tighten screw; connect to other end of connector
and you are ready to go.
Note: Always unplug battery after mission. A battery tender has been supplied to maintain battery.
DO NOT USE FAST CHARGER ON BATTERY. If battery is dead; upon starting engine with primary pull
start it will recharge.
Maintenance on the battery is clean connections on wiring; clean exterior of battery; apply grease to
connectors; store in dry place. Use maintainer to maintain while not in Raider. Disconnect for long
periods of time.

12
4. FUEL & ENGINE OIL - TC-W3 OR RAIDER OIL MUST BE ADDED TO
BLADDER for operation of Raider 50 on any fuels.
4-1 Fuels: Gasoline (Primary) other fuels JP-5/8; kerosene; Diesel
DANGER
A CAU T I ON
DO NOT mix di ffer en t b ran ds of oi l.
Using different brands of oil, or di fferent type of oil even If the
b rand is the same, may cause gelli ng, resulting in possibl e filter
screen blockage. Thi s coul d result in serious engi ne damage beca use
of impaired lubrication performance. Synthetic TC-W3.
When fuel vapors are present , they coul d cause an explosion or fi re.
• Do not smoke nea r gasol i ne and other fuels .
• Do not overfi ll fuels and additives when filling bladders.
Any fuel spilt should be wiped up immediately.
Notes:
Gasol ine
Unl eaded regula r gasoline minimum of 87 Octane is highl y
recommended for the Raider outboard. (9 1 by research octane
rating ) .
JP-5/8: YOU MUST PLACE RAIDER ADDITIVE IN BLADDER AND
ALONG WITH TC-W3. BOTH MUST BE USED WHEN USING
HEAVY FUELS.
Additive will reduce smoke and carbons build up during idle.
Shown is battery integrated with
Raider 50. Power plug is red/black
and is easily disconnected.
To remove a single “screw” is holding
the battery into the assembly.

5-2. Starting
The Raider 50 has three starting capabilities.
a) Primary is manual pull start. This method simply uses the pull start located at the
top of the Raider.
b) Secondary starting is the “push button” which engages the battery. If the battery
is dead if you start the Raider it will recharge in minutes.
c) Third method is emergency only. In the tool kit (BII) are tools that allow the pull
starter (a) to be removed. In the BII you will find a rope that can be wound around
fly wheel to manually start the Raider 50.
5.3. Manual Rope Start (Last resort for starting)
a. Set the Shift Lever to Neutral.
(2) Remove the Upper Engine Cover. Then,
b. Remove the “Emergency Kit.” Remove the Recoil Starter Assembly using the tools in the BII
(Emergency Tool Kit). Three bolts need to be removed (10 mm and 13 mm). Remove snap on side of
starter assembly. Remove. Rope pull starter is located inside BII –Tool Kit.
c. Prime engine (3 pumps)
CA U T ION
