Essentially a detuned version of the E-TEC 150, the 2.6-liter V-6 oil-injected engine weighs 418 pounds, 28 pounds more than the **Evinrude E-TEC 130 **V-4 outboard. Still the 135 H.O. is the lightest in its horsepower class. This is important in minimizing draft -- a key consideration for fishing shallow-water for species such as redfish, bonefish and permit. Factory-tuned for high-performance applications, the 135 H.O. is available in 20- and 25-inch models, including counter rotation on the 25-inch version for twin-engine installations.
