2019 Evinrude E25DRSL 15 H.O. to 150 HP E-TEC Evinrude E-TEC sets the performance standard for outboard engines. HIGH OUTPUT SERIES The Evinrude E-TEC H.O. series are performance engines to the max. Each engine is tuned for extra power and speed. If you like pushing limits in horsepower, speed and torque, then consider our High Output Series. AUTO-STORAGE The auto winterization feature fogs the engines itself in minutes, with no trip to the dealer. An Evinrude E-TEC engine does not require belts, camshafts or exhaust valves, which means there are fewer parts to wear down or malfunction than a four--stroke outboard. Extend the life of your outboard and your boating season. MORE MILES PER HOUR Get even more extra miles per hour with the Straight Leading Edge gearcase. The Evinrude SLE gearcase features high-efficiency water pickups and a weed-slicing shape up front, for a cooler-running engine and ultimate durability and reliability in the long run.
