Yamaha LF300UCB2 300HP Outboard – 30in Shaft, Counter Rotation

Description

Blinding coastal sun glare cannot degrade the Pearlescent White Yamaha LF300UCB2 while it balances towering offshore luxury yachts. This 4.2-liter 24-valve DOHC block translates electronic fuel injection data into explosive midrange torque, pushing deep-draft twin-engine catamarans safely through aggressive morning tides. Taping your exact transom bracket ensures this white 300hp ultra long shaft outboard fits properly without generating excessive lower unit drag.

Prevent severe propeller ventilation across heavy ocean chop by leveraging the 30-inch extended counter-rotating midsection to reach solid green water instantly. You neutralize starboard propeller walk completely without experiencing sudden thrust loss or cooling system failures in steep waves. Yamaha protects the 263 kg assembly using multi-stage marine primers beneath the white paint. This physical barrier stops galvanic blistering when repowering luxury offshore yachts in high-salinity environments.

Key Features of Yamaha LF300UCB2

• Multi-Point Sequential EFI: Calculates precise fuel requirements continuously, eliminating carburetor hesitation and ensuring crisp acceleration across the RPM band.
• 30-Inch Ultra-Long Shaft: Reaches incredibly deep beneath towering offshore transoms, preventing water pump starvation in heavy ocean chop.
• Hydraulic Power Trim: Adjusts the running angle dynamically via the binnacle switch, optimizing bow attitude across aggressive offshore swells.
• Remote Steering Compatibility: Accepts standard mechanical cables directly from your forward helm, integrating flawlessly with classic steering consoles.
• 50-70 Amp Charging Alternator: Generates massive electrical current continuously, keeping deep cycle house batteries fully charged for heavy-duty marine electronics.
• Pearlescent White Finish: Reflects intense ultraviolet sunlight physically, preventing cosmetic fading and matching premium fiberglass hull finishes perfectly.
• Through-Prop Exhaust: Channels toxic combustion gases directly underwater, keeping the aft operator station completely free of choking smoke.
• Accessible Oil Filter: Allows technicians to swap out lubrication components rapidly without removing major cowling panels during scheduled maintenance.
• Counter-Rotating Gearcase: Cancels the massive lateral thrust of a starboard engine, keeping twin-engine performance hulls tracking perfectly straight underway.
• Clean Four-Stroke Combustion: Burns fuel highly efficiently without oil mixing, easily meeting strict local waterway emissions regulations and EPA standards.

Why Choose Yamaha LF300UCB2

This advanced white-finished 30-inch block acts strictly as a port-side power plant for twin-engine applications demanding extreme shaft lengths and pristine aesthetics. Mounting it on a standard 25-inch transom will cause massive lower unit drag. Installing a reliable extra long shaft outboard ensures safe harbor returns.

• Verify your transom bracket accommodates a 30-inch shaft length safely.
• Install corresponding mechanical control cables sized exactly for your specific boat length.
• Keep coastal waters clean by running highly regulated four-stroke engine configurations.

Ideal Application and Vessel Fitment

This 300-horsepower counter-rotating block is engineered strictly for extra-deep transom offshore vessels, luxury offshore yachts, and multi-engine catamarans demanding a 30-inch shaft and pristine aesthetics. Operating as a highly reliable drive, it neutralizes propeller walk instantly, keeping performance hulls tracking perfectly straight at high cruising speeds. It thrives in competitive coastal environments where balancing massive thrust requires an extended reach without sacrificing aesthetic appeal.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year 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. Mulmotor provides product-information support before purchase and assistance with order-related questions.
