Outboards
MULTI-FUEL SUBMERSIBLE ELECTRIC START OUTBOARD ENGINES
The Raider series of outboard motors are dedicated to the Marine Raiders established by the United
States Marine Corps during WW II and are said by many to be the first United States special operations
force. Handpicked from the elite, these men were given specialized training and the best equipment.
They distinguished themselves during the conduct of clandestine amphibious landings, utilizing small
inflatable boats, operating behind enemy lines in direct support of combat operations in the Central
Pacific and Solomon Islands. Even though the Raiders were disbanded at the close of WW II the need for
specially trained warfighters and the requirements for specialized equipment did not. Today’s Special
Operations Forces (SOF) under the United States Special Operation Command (USSOCOM) are expected
to conduct similar and far more demanding missions, to that end and with those warfighters in mind the
Raider OBM is specifically developed for SOF that routinely operate within the often unforgiving, highly
demanding, dynamic maritime environment.
WHO WE ARE
•Raider Outboards, Inc. is a-US owned and operated company based in Central Florida near
Kennedy Space Center, located in the Space Port Commerce Park. We design and produce multi-
fuel, submersible, lightweight outboard motors and associated parts that include a Safety Jet;
transom plates; carts and transportation cages. Our markets include Department of Defense
(DOD), Other Government Agencies (OGA), National and Local Law Enforcements and First
Responder Services, Search & Rescue and commercial/retail.
•The Raider, patent pending, Safety Jet can be purchased in a kit which retrofits a propeller drive
to a jet pump system. The Safety Jet was designed to improve safety for swimmers and divers in
both real-world and training situations. The Safety Jet is excellent for “brown” water operations
where search and rescue operations routinely happen in which higher probabilities of striking
submerged objects exist. For coastal or beaching operations in unfamiliar waters it provides
additional protection from rocks or coral easily absorbing hits that could ruin propellers when
moving to and from a beach landing site.
•Raider also provides a series of transom plates that are attached to the transom of the Combat
Rubber Raiding Craft (CRRC). The transom plates have single and dual motors configurations. The
transom plates provide centerline alignment and safety if the motor clamps loosen under
vibration. Specialty items like extended handles, extended fuel hose connections, outboard
motors carts and transportation cages are also available.

EMERGENCY STOP SWITCH
The Emergency Stop Switch will stall the outboard motor when the stop switch tether is pulled off. This
stop switch tether can be attached to the operator of the outboard motor to minimize or prevent
injuries from the propeller in case the operator falls overboard. We highly recommend use of the
Emergency Stop Switch tether.
RAIDER MAINTENANCE TOOL KIT
The Raider Maintenance Kit (RMK) is a complete tool
set that is specifically designed and provides
Operators and Field Service Technicians with the
necessary tools to perform routine maintenance
actions or intermediate level motor troubleshooting
and repair to the component level. The tools are
stowed and secured in a waterproof case for ease of
transport and protection from harsh environmental
conditions. For inquiries into purchase of the RMK
please contact Raider at [email protected]
or 321-567-2307 by phone for information.
Accidental activation of the Emergency Stop Switch (such as the tether 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.

CAPABILITIES/FEATURES
Multi-fuel
Dependent upon fuel available. The Raider 50 HP is capable of using multiple fuel sources for operation.
Gasoline, is the recommended fuel but should the mission or situation dictate various types of Heavy
Fuel combined with the Raider Additive may be used. Regardless of fuel type utilized for operations there
still exists the requirement for mixing with 2 cycle oil at the ratio of 50:1.
Submersible
Allows for full submersion, in salt water, without bagging to a depth greater than 65ft for periods
exceeding 24 hours.
Dewatering
Upon recovery to the surface fully operational within 10 minutes. Easy instructions for dewatering are
provided affixed to each engine cowling of every outboard motor. Most operators, with practice and
adherence to the provided instructions, restore the motor to operations within two minutes of surfacing.
Skilled operators are able to achieve lite off in as few as 30 seconds.
Air Deployable
When required is capable of being dropped from both fixed wing and rotary aircraft. Battery cutoffs are
available to preserve start battery life in drop packages for over 180 days. Prior to drop, the operator
enables the start battery should expeditious start be required on the drop zone.
Lightweight
Maneuverable through the hatch of a Submarine or mounting when underway. The motor is easily
maneuvered by two personnel through the hatches of ships or submarines by using the installed
reinforced no slip grab handles and rails. The special rail design allows the motor to be stowed in an
upright position of the deck or pallet instead of laying on its side.
Electric Start
Provides fast starting in duress situations and aids in dewatering. The installed Acid Glass Matt Battery
adds the ability to start the motor without the use of the recoil starter. This capability may prove to be
invaluable where starting the motor is not practical via the primary method due to motor damage,
operator injury, or prevailing environmental conditions will not afford such. When used with dewatering
it rapidly expels any water through the decompression valves.

Tactical Communications Power Interface
Power and charge tactical communications systems. Various types of connectors may be installed per
the requirement of the operator. Power tactical radio systems through battery eliminators, charge cell
phones or even power a spot light.
Bolt on Safety Jet
Prevents injury to personnel from inadvertent contact with the propeller. Moreover, provides increased
reliability during beaching or Search and Rescue applications supporting hurricane relief and emergency
response. Protects crafts propulsion systems when transiting through shallow and flooded areas from
unseen obstructions that when struck would normally render a craft dead in the water.
Transportation Cage and Cart.
Allows for safe secure storage of motor when not in use or being transported over the road or by air.
Raider provides two-part system, consisting of a cart and cage. The cart provides a mobile mount for the
performance of maintenance actions and repairs. For safe secure storage the cart maybe locked into
place inside the Transportation Cage. This provides extra protection when conducting movement via
land or by Military Air ensuring your motor arrives in theater ready for immediate operations.
Engine Cover
Protects motor from prevailing environmental conditions should the need require stowage in less than
ideal conditions or outside. A specially designed breathable material allows moisture to evaporate.
Transom Plates
Provides a means for repetitive, expeditious, safe, and secure mounting of the motor on any marine craft
transom. These plates provide a guide for the stern bracket of the motor that will automatically center
the Raider 50 to the keel (center line) of the craft. Then simply tighten the stern bracket screws.
