Yamaha VF115XB 115HP – V Max Sho 25″ Shaft Remote Mechanical

Yamaha VF115XB 115HP V MAX SHO

The Yamaha VF115XB pairs a 1832cc 4-cylinder DOHC 16-valve V MAX SHO engine with a performance gearcase, finished in Classic Gray at 377 lbs. Built for high-transom bass boats, bay boats, and multi-species hulls in Mulmarine’s reliable marine propulsion systems lineup, the 25-inch extra-long shaft is calibrated for exceptional hole-shot acceleration and vessel agility.

Peak output holds through the 5300-6300 RPM range using a TCI micro-computer and Precision EFI system. The 2.15:1 gear ratio translates engine power into immediate thrust, letting high-performance hulls plane instantly even under heavy loads. US tournament anglers lean on this Japan-engineered SHO platform for reliability and a strong power-to-weight ratio.

V MAX SHO Performance Engineering

The 1.8-liter block gives higher torque and faster acceleration than traditional 115HP competitors, maximizing air intake and exhaust efficiency for rapid hole-shot response under tournament loads.

Extra-Long 25-Inch Shaft Utility

The 25-inch shaft is calibrated for high-transom vessel dimensions on modern bay boats and deep-V skiffs, preventing propeller aeration in following seas.

Tournament Hole-Shot Acceleration

This engine is tuned with a specialized ignition curve and performance gearcase to minimize time-to-plane, pushing heavy bass boat hulls through the water.

High-Output 35-Amp Alternator

The 35-Amp alternator supports high-draw fishfinders, livewell pumps, and navigation displays throughout the day.

NMEA 2000 Digital Connectivity

This engine is NMEA 2000 certified for engine data transfer to compatible displays and sonar units, showing RPM, fuel flow, and diagnostics.

Routine Maintenance Care

This V MAX SHO engine runs high-quality sacrificial anodes and a fresh-water flushing system to prevent galvanic corrosion. Pro Tip: flush the internal cooling passages with fresh water after every launch to protect the 1832cc block from salt buildup.
