Yamaha LF300XA 300HP Outboard – 25in Shaft, Counter Rotation, V6

Description

Massive port-side steering torque disappears instantly the moment the mechanical Yamaha LF300XA begins counter-rotating on your transom. The naturally aspirated 4.2-liter V6 block breathes enormous volumes of air, translating traditional cable inputs into brutal acceleration for loaded deep-V fishing boats. A quick tape measure check validates this 25 inch mechanical steer counter rotating outboard fits your twin-engine bracket perfectly without creating excessive lower unit drag.

Balance massive starboard propeller walk permanently by integrating this specialized left-hand rotation lower unit into your standard mechanical rigging setup. You steer heavy coastal fishing boats precisely using traditional cables without requiring complex fly-by-wire network conversions. Yamaha equips the 253 kg powerhead with a high-output 50-amp alternator enclosed in anti-corrosion marine aluminum. This heavy-duty electrical generation ensures continuous power delivery when repowering older offshore vessels for daily saltwater exposure.

Key Features of Yamaha LF300XA

• Counter-Rotating Gearcase: Offsets the lateral thrust of standard engines, eliminating steering pull and keeping massive twin-engine hulls tracking dead straight.
• 4.2-Liter DOHC Block: Breathes massive volumes of clean air efficiently, generating 300 horsepower effortlessly to lift heavy fiberglass hulls onto plane.
• Remote Mechanical Control: Accepts standard mechanical cables directly from your forward helm, integrating flawlessly with classic steering consoles.
• 25-Inch Extra-Long Shaft: Reaches deep below elevated offshore transoms, keeping the propeller fully engaged in clean undisturbed water.
• 50-Amp High-Output Alternator: Generates massive electrical current continuously, keeping deep cycle house batteries fully charged for heavy-duty marine electronics.
• 1.75:1 High-Speed Gearcase: Spins aggressive high-pitch propellers efficiently, translating massive big block torque directly into forward vessel momentum.
• Hydraulic Power Trim: Adjusts the running angle dynamically via a console 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.
• Through-Prop Exhaust: Channels toxic combustion gases directly underwater, keeping the aft operator station completely free of choking smoke.
• Clean Four-Stroke Combustion: Eliminates messy two-stroke oil reservoirs, keeping your bilge completely clean while meeting strict clean water standards.

Why Choose Yamaha LF300XA

Choosing this specific engine limits installation entirely to the port side of 25-inch tall transoms rigged with standard mechanical forward steering wheels. You cannot operate this via digital fly-by-wire controls. Correcting your rigging geometry is a mandatory step when building a cable steered twin outboard setup safely.

• Measure the vertical distance from your twin-engine transom edge to the keel bottom.
• Install corresponding mechanical control cables sized exactly for your specific offshore hull length.
• Keep coastal waters clean by running highly regulated four-stroke engine configurations.

Ideal Application and Vessel Fitment

This 25-inch mechanical-steer outboard excels on deep-V twin-engine center consoles, heavy aluminum offshore fishing boats, and classic fiberglass hulls carrying massive payloads. By integrating a proven 4.2-liter displacement block with standard mechanical cable controls and counter-rotation, the engine acts as an incredibly reliable mechanical workhorse. The extended shaft allows captains to operate safely in massive ocean swells, making this twin engine mechanical rigging setup an absolute necessity for commercial offshore operators.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Limited Warranty alongside exceptional factory support. Registered commercial applications fall under a strict 1-Year Commercial Warranty with zero corrosion coverage 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.
