RAIDER Outboards

DUAL ENGINE SYSTEM

The Raider series of outboard engines are dedicated to the Marine Raiders established by the

United States Marine Corps during WWII 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 WWII 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.
