Features: The I-MARS 35 Horsepower Outboard Motor is a combination of the 35 horsepower Military Amphibious Reconnaissance System (MARS) outboard motor and a pump jet. The pump jet takes the place of the propeller in order to provide the user with a safer outboard motor. The I-MARS gives the Marine Corps the capability to insert and extract personnel from the shore with the CRRC more safely, and without degrading the overall performance of the old MARS outboard motor or CRRC. The I-MARS can be operated in any environment in which the MARS outboard motor previously has been used.
