*Rated Output 140 C.I. 165 HP with 170 LB FT Torque.
Emphasizing longevity, Ultima® El Bruto® engines combine high quality components with affordable prices giving you the best value available.
Our proven combinations deliver more horsepower and due to our exclusive balancing methods, we feel they are the smoothest engines on the market today.
All castings are made from C355 aluminum, a common military alloy known for its stability over multiple heat cycles. The engine components are machined on state of the art CNC equipment for guaranteed dimensional accuracy and repeatability. Our customers agree these engines are
the best value anywhere.
