Yamaha LF150XSA2 150HP in White DEC 25″ Shaft Counter Rotation

Yamaha LF150XSA2 150HP White DEC DES

The Yamaha LF150XSA2 pairs a 2.7L 4-cylinder DOHC 16-valve engine with counter-rotation gearing, finished in Pearlescent White at 500 lbs dry — built with fully integrated steering for high-end multi-engine platforms in Mulmarine’s outboard engine technology lineup. The 25-inch shaft and Integrated Digital Electric Steering (DES) give the responsiveness and clean rigging modern luxury fiberglass hulls need.

Peak output holds through the 5000-6000 RPM band, using a TCI micro-computer and Precision Multi-Point EFI system. The 2.00:1 gear ratio converts engine energy into torque that gets a hull planing without hesitation. US offshore boaters lean on this Japan-engineered platform for reliability in twin-engine configurations.

Technical Specifications of Yamaha LF150XSA2

• The 2.7L 4-cylinder DOHC architecture delivers 150 horsepower with strong volumetric marine efficiency.
• The White 227 kg build includes a 25-inch shaft for specialized offshore boat transom configurations.
• Integrated Digital Electric Steering (DES) gives effortless vessel handling and precise control at all speeds.
• Digital Electronic Control (DEC) and Helm Master EX compatibility allow smooth helm management.
• The counter-rotation (left-hand) gearcase balances steering torque in twin-engine installs.
• Precision multi-point EFI guarantees consistent combustion across the 5000-6000 RPM band.
• Coverage comes from a 3-year limited factory warranty and Japanese maritime engineering.

Integrated DES Technology

DES gives a smooth, responsive boating experience without external hydraulic lines, keeping the bilge clean while offering adjustable steering friction for the captain.

Digital Command DEC Interface

DEC gives smooth, cable-free throttle and shifting, fully compatible with Helm Master EX for advanced vessel positioning and joystick control during technical maneuvers.

Counter-Rotation Precision

The counter-rotation gearcase spins the propeller left-hand, and paired with a standard-rotation motor, it eliminates the steering pull common in high-horsepower twin-engine vessels.

Routine Care Protocol

This digital EFI engine runs high-quality sacrificial anodes to keep galvanic corrosion in check in saltwater coastal environments. Pro Tip: flush the internal cooling passages with fresh water after every launch to maintain cooling system integrity.
