Custom offshore catamarans tracking across massive ocean swells rely on the white Yamaha LXF425USB2 for absolute port-side stability. The counter-rotating 5.6-liter V8 engine injects fuel directly into the cylinders, delivering explosive low-end torque to lift extra-heavy displacement hulls. Measuring your exact mounting height validates this 30 inch shaft white counter rotating outboard places the internal cooling intakes deep into undisturbed green water.

Eradicate exhausting steering friction at high speeds by utilizing the factory Digital Electric Steering actuators for sports-car-like handling. You pilot fast twin-engine coastal vessels with absolute single-finger precision without installing bulky external hydraulic pumps. Yamaha builds the massive 464 kg lower unit using multi-stage marine primers beneath the Pearlescent White finish. This physical barrier stops galvanic blistering when repowering ultra-luxury offshore yachts in high-salinity coastal environments.

Key Features of Yamaha LXF425USB2

- Pearlescent White Finish: Reflects intense ultraviolet sunlight physically, preventing cosmetic fading and matching premium fiberglass hull finishes perfectly.
- Counter-Rotating Gearcase: Cancels the massive lateral thrust of a starboard engine, keeping twin-engine performance hulls tracking perfectly straight underway.
- 30-Inch Ultra-Long Shaft: Reaches incredibly deep beneath towering offshore transoms, preventing water pump starvation in heavy ocean chop.
- 5.6-Liter V8 Block: Breathes massive volumes of clean air efficiently, generating 425 horsepower effortlessly to lift heavy fiberglass hulls onto plane.
- Integrated Digital Electric Steering (DES): Eliminates messy external hydraulic cylinders completely, delivering immediate directional changes and zero steering fatigue during long runs.
- Direct Fuel Injection: Atomizes fuel perfectly inside the cylinder at extreme pressure, delivering crisp throttle response and maximizing fuel efficiency across the operating range.
- High-Output Alternator: Outputs massive charging power, keeping demanding radar systems and heavy-duty livewell pumps fully powered offshore.
- Hydraulic Power Trim: Adjusts the running angle actively via the binnacle switch, optimizing bow attitude across aggressive offshore swells.
- Anti-Corrosion Castings: Blocks severe galvanic decay physically, protecting the aluminum powerhead block across decades of daily saltwater exposure.
- Clean Four-Stroke Combustion: Burns fuel highly efficiently without oil mixing, easily meeting strict local waterway emissions regulations and EPA standards.

Why Choose Yamaha LXF425USB2

This advanced white-finished 30-inch block acts strictly as the port-side companion in a digital twin-engine application demanding extreme shaft lengths. Substituting a mechanical control model sacrifices electronic shifting entirely. Upgrading your digital throttle syncing network is mandatory for smooth dual-engine communication.

- Verify your twin-engine transom bracket accommodates a 30-inch shaft length safely.
- Link the DEC module to your master binnacle to synchronize shift commands perfectly.
- Keep coastal waters clean by running highly regulated four-stroke engine configurations.

Ideal Application and Vessel Fitment

This 30-inch white counter-rotating outboard is engineered strictly for extra-deep transom offshore vessels, large luxury cruisers, and high-transom multi-engine applications demanding a 30-inch shaft and pristine aesthetics. Operating as a highly reliable digital port-side drive equipped with integrated DES, it neutralizes propeller walk instantly, keeping twin-engine performance hulls tracking perfectly straight at high cruising speeds. It thrives in competitive coastal environments where balancing massive thrust requires precise fly-by-wire synchronization alongside beautiful hull-matching aesthetics.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Limited Pleasure Warranty alongside exceptional factory support. Registered commercial applications fall under a strict 1-Year Commercial Warranty with separate terms applied to the block. Scheduled maintenance requires replacing gearcase lubricants and changing oil filters at manual-specified intervals. Always save all physical service records. Your engine serial number acts as the only way to source exact genuine replacement parts. For product details and order support, Mulmotor offers assistance before your purchase is placed.
