Yamaha F250USB2 250HP – DEC 30″ Shaft Standard Rotation in White

Yamaha F250USB2 250HP White V6

The Yamaha F250USB2 pairs a 4.2L 24-valve DOHC V6 with standard rotation, finished in Pearlescent White at 553 lbs dry — a strong power-to-weight ratio for premium offshore vessels. The 30-inch extra-long shaft is built for high-transom platforms and multi-engine configurations in Mulmarine’s reliable marine propulsion systems lineup.

Peak output holds through the 5000-6000 RPM band via a sophisticated multi-point EFI system. The 1.75:1 gear ratio converts that energy into smooth low-end torque for quick hull planing on heavy luxury hulls. Offshore boaters lean on this Japan-engineered platform for reliability and the precision of Integrated Electric Power Steering (DES).

V6 Premium White Finish

The F250USB2’s Pearlescent White finish matches the aesthetic on luxury center consoles. The 24-valve V6 configuration maximizes air intake for rapid, responsive hole-shot acceleration under heavy loads.

Yamaha 250HP DES Steering

Integrated Electric Power Steering (DES) gives a smooth, responsive experience without hydraulic lines, keeping the bilge clean while giving the operator adjustable steering friction.

30-Inch Extra-Long Shaft

The 30-inch shaft is calibrated for high-transom vessel dimensions, preventing propeller aeration while holding secure mechanical leverage through turns.

Digital Control DEC Interface

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

Yamaha Limited Warranty

This engine includes a 3-year limited factory warranty covering essential mechanical systems and structural components against manufacturing defects.

Luxury Vessel Compatibility

This 250HP motor suits modern luxury fiberglass hulls needing extra-long shaft length, with a 553 lbs build balancing stability and planing speed.

Pro Maintenance Care

This digital V6 runs high-quality sacrificial anodes to keep galvanic corrosion in check daily. Pro Tip: flush the engine with fresh water after every launch to maintain cooling and protect internal components from salt buildup.
