On Sale Twin Yamaha 300XCB Four-Stroke V6 25" Set New Condition and ready to install, consists of one standard rotation engine (F300XCB) and one counter rotation engine (LF300XCB) to neutralize the steering torque on twin-engine boats.

• Integrated Rigging & Advanced Steering: The XCB designation features digital controls and is designed to interface seamlessly with remote hydraulic steering systems, or upgraded digital electric steering. It is fully compatible with Yamaha’s Helm Master EX system  for joystick docking, autopilot, and pattern tracking. 
• Thrust Enhancing Reverse Exhaust: This system redirects exhaust bubbles away from the propeller blades when in reverse or at low RPMs. It significantly improves grip and stopping power when backing down or maneuvering into a slip. 
• Variable Camshaft Timing (VCT): This tech advances and retards the camshaft timing based on engine RPM, maximizing low-to-mid-range torque. It delivers a much faster hole shot and responsive acceleration. 
• TotalTilt™ Function: A simple double-tap of the trim button automatically tilts the engine completely up or down. This minimizes time spent holding down buttons and simplifies trailering or shallow-water operation. 
• Plasma-Fused Cylinders: Instead of heavy steel liners, the cylinder walls feature plasma-fused material that is 60% harder than steel but much lighter. This maximizes displacement (4.2L) while keeping the engine significantly lighter than competitors
