features

Extra Charging Power

A powerful alternator supports the battery system, helping to ensure you can crank your engine and get back to weigh-in after a long day running onboard electronics.

Performance-Inspired Gearcase

The 150hp Pro XS gearcase is optimized for fast hole shots, top speeds and enhanced control at wide-open throttle. The 115hp engine can be paired with the Command Thrust (CT) gearcase. It’s designed to turn a larger pop, providing greater acceleration, better handling, awesome maneuverability and superior control.

Transient Spark Technology

Transient Spark technology (150hp model) electronically adjusts spark plug timing to optimize low-end power. The result is performance you can feel – greater torque, faster hole shots and sensational acceleration.

Intelligent Power Management

Idle charge battery-management technology automatically increases idle rpm to boost alternator output and recharge low batteries.

Tiller Handle

If you run a tiller boat, you can still enjoy the speed and exhilaration of a performance-tuned Pro XS engine. The tiller handles for both the 115 and 150hp engines are available with integrated Troll Control rpm-based speed control. The Big Tiller, available for the 150hp engine, can be paired with Mercury power steering.
