The 150R outboard is the perfect entry point for sophisticated boaters seeking the performance and luxury refinement of Mercury Racing R-Series power. Featuring a smooth and efficient V6 powerhead coupled with advanced Digital Throttle & Shift (DTS) control capability, the 150R is the premium propulsion choice for high-performance RIBs and runabouts. The high-displacement, quad-cam design of the 3.4L V6 powerhead generates serious torque, especially at mid-range, for quick acceleration and exciting speeds. With a balanced powerhead and sophisticated, vibration-dampening cowl design, the 150R delivers an exceptionally smooth and quiet ride at any speed. Digital Throttle & Shift (DTS) controls deliver smooth, quiet shifting and instant throttle response, with zero hesitation. With integrated SmartCraft® technologies and an intuitive user interface, DTS puts you in complete command of your adventures. Strong and rock-steady, the Mercury Racing tri-ram Conventional MidSection (CMS) features standard engine mounts and is available in 20-inch and 25-inch shaft lengths. The 150R features a 4.8-inch gearcase with a 1.85:1 ratio and is available in both lefthand and righthand rotations for single- and twin-engine installations (25-inch shaft length only).
