2017 Mercury 90ELPT Mercury 90ELPT - Electric Start, 20" Shaft, Power Trim The same lifetime maintenance-free valvetrain design found in our 150 FourStroke engines makes the 75-115hp FourStroke outboards incredibly durable. The Mercury Enertia propeller is the perfect complement to the 75 - 115hp FourStroke Command Thrust gearcases. Designed specifically for large fourstroke outboards with a revolutionary low-diameter / high-blade-area design and cast with the Mercury proprietary X7® propeller alloy, Enertia delivers phenomenal acceleration, top speed and durability. Less weight and high displacement mean Mercurys new 75 - 115 FourStrokes generate abundant torque and immediate power. Because they dont have to work as hard as heavier engines or those with lower displacement, these engines make boats plane faster, accelerate better and provide optimal fuel efficiency at cruising speed.

Do 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 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. The Mercury 115 FourStroke is quieter than the Yamaha F115B across the rpm band.At idle, the Mercury is four decibels quieter than the Yamaha – the Yamaha is 25% louder.At cruising speed, where normal conversations occur, the Yamaha generates almost 15% more noise.At wide-open-throttle, the Mercury is more than eight decibels quieter – the Yamaha is 50% louder.Testing performed by Mercury PD&E NVH staff at a Mercury Marine hemi-anechoic chamber (Sound Lab). The Mercury 115 FourStroke has less vibration and rides smoother than the Yamaha F115B.At forward idle, the Mercury’s vibration level at the driver’s seat is up to 50% lower than the Yamaha.On the transom, the Yamaha puts out nearly five times more vibration than the Mercury – both at cruise and at full throttle.The Mercury Enertia propeller is the perfect complement to the 75-115 FourStroke CommandThrust gearcases.
