All Evinrude engines are two-strokes and have an onboard two-stroke oil tank that has a capacity of 3 gallons. They run on 87-octane fuel. Evinrude sells the motors with a five-year warranty on the engine and against corrosion. After the engine is purchased, the first required service interval is 500 hours. The E-Tec G2 series comes with hydraulic steering integrated into the motor’s midsection and digital throttle and shift for smooth operation. Evinrude also includes its i-Trim automatic trimming system that can easily be shut off if an owner wants to control the trim himself. With 81 degrees of positive trim, the motors tilt completely out of the water, which is a positive feature for boaters in salt water. For owners who like to customize their boats, the E-Tec G2 series is available in side-panel and accent colors that number well into the hundreds.
