2017 Mercury Marine 90ELPT Command Thrust FourStroke
Forget everything you know about FourStroke outboards. Ours change the game. Completely. They’re tougher, smaller, and lighter than any other FourStroke on the water. With a combination of performance and efficiency that will take your time on the water to a whole new level.
Mercury® FourStroke OutboardsPART REVOLUTION. PART EVOLUTION.
Embrace possibility. Adaptable, reliable, and able to outperform any outboard in its class.
Features may include:
Lightweight & Fuel EfficientMercury’s world-renowned engineering team has packed incredible power into these lighter, compact four-cylinder single-overhead-cam engines. The 115hp weighs 20 pounds less than its closest four-stroke competitor, making it the world’s lightest low-emissions outboard in its power range.
Dry weight specification is for the lightest-version model. Comparative weights refer to base engines without oil, propeller or integral steering cylinder. Weights based on Owner’s Manual specifications.
Worry-freeThe same lifetime maintenance-free valvetrain design found in our 150 FourStroke engines makes the 75-115hp FourStroke outboards incredibly durable.
Calculate your fuel savingsThe Mercury Fuel Savings Calculator will allow you to easily calculate the possible fuel savings of a Mercury FourStroke outboard!
Choose how you use your boat, select the TwoStroke and FourStroke horsepower - and our tool will show your potential fuel savings. If you're looking to upgrade or add more power, you can even choose different FourStroke and TwoStroke horsepower options!
Counter-RotationDo you like to boat offshore even though you’re not in the market for a big boat? For the first time, Mercury is offering a 115hp FourStroke with left-hand rotation. Two of these mid-range monsters on your transom provide the maneuverability and get-home safety of higher-horsepower twins at a price that’s easier on your wallet. Unlike competitive dual 115hp engines, dual 115 Mercury FourStrokes are Command Thrust models, which swing V6-class propellers, such as Enertia series to deliver improved acceleration and better boat control in rough water.
*Available only on 115 hp
Bigger Footprint.The larger Command Thrust gearcase creates a bigger footprint in the water, which provides more leverage to control your boat. The larger torpedo, combined with a bigger-diameter prop, can lift a heavy boat onto plane more easily and hold it there at lower speeds without impacting top speed.
Quieter Than the Competition.The Mercury 115 FourStroke is quieter than the Yamaha F115B across the rpm band.

Smoother Than the Competition.The Mercury 115 FourStroke has less vibration and rides smoother than the Yamaha F115B.
