Yamaha VF115XB 115HP Outboard – 25in Shaft, SHO

Description

Heavy performance pontoons achieve blistering top speeds once the Yamaha VF115XB applies its Super High Output tuning to the water. The newer generation 1.8-liter DOHC block forces massive volumes of air through the intake, lifting 22-foot deep-V hulls onto plane instantly. Taping your exact transom bracket ensures this yamaha sho 115hp extra long shaft outboard fits properly without generating excessive lower unit drag.

Maintain optimal running attitudes dynamically across rough water by engaging the hydraulic power trim and tilt system from your forward console. You tuck the 175 kg engine inward instantly to push the bow down and slice through morning chop safely. Engineers cast the massive lower unit using specialized anti-corrosion marine aluminum alloys. This physical barrier stops galvanic decay when repowering performance pontoons for continuous saltwater operation.

Key Features of Yamaha VF115XB

• Newer Generation SHO Tuning: Optimizes fuel maps and ignition timing dynamically, delivering blistering holeshot acceleration for heavy pontoon boats.
• 25-Inch Extra-Long Shaft: Reaches deep below elevated offshore transoms, keeping the propeller fully engaged in clean undisturbed water.
• 1.8-Liter DOHC Block: Breathes massive volumes of clean air efficiently, generating 115 horsepower effortlessly to lift heavy fiberglass hulls onto plane.
• Electronic Fuel Injection: Calculates precise fuel requirements continuously, eliminating carburetor hesitation and ensuring crisp throttle response across the RPM band.
• Hydraulic Power Trim: Adjusts the running angle dynamically via a console switch, optimizing bow attitude across aggressive offshore swells.
• Remote Mechanical Control: Accepts standard mechanical cables directly from your forward helm, integrating flawlessly with classic steering consoles.
• 35-Amp Charging Alternator: Outputs constant electrical current while running, keeping deep cycle batteries topped off for commercial aerators and navigation lights.
• 2.15:1 Gearcase Ratio: Spins aggressive high-pitch propellers efficiently, translating inline-four torque directly into forward vessel momentum.
• Anti-Corrosion Castings: Blocks severe galvanic decay physically, protecting the aluminum powerhead block across decades of daily saltwater exposure.
• Clean Four-Stroke Combustion: Eliminates messy two-stroke oil reservoirs, keeping your bilge completely clean while meeting strict clean water standards.

Why Choose Yamaha VF115XB

Choosing this specific engine limits installation entirely to 25-inch tall transoms rigged with standard mechanical forward steering wheels. You cannot operate this via a tiller handle safely. Correcting your rigging geometry is a mandatory step when replacing older mechanical outboards.

• Measure the vertical distance from your top 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 bay boats, heavy aluminum offshore fishing boats, and massive performance pontoons carrying heavy payloads. By integrating a proven 1832cc displacement block with standard mechanical cable controls and SHO mapping, the engine acts as an incredibly reliable mechanical workhorse. The extended shaft allows captains to operate safely in massive ocean swells, making this a necessity when repowering performance pontoons for coastal use.

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.
