Yamaha 115hp Jet Drive Outboard Motor 25" Shaft Standard Rotation White F115JB

This 115hp jet drive marine outboard motor is designed for shallow-water and obstacle-rich marine environments. It features a 25" shaft with standard rotation, providing reliable propulsion for vessels operating in shallows, rocky-bottom rivers, shoals, and white-water rapids. The powerplant is a 1.8L jet drive four-stroke engine with 4 cylinders, utilizing electronic fuel injection (efi) for optimal combustion efficiency and throttle response.

Propeller-free operation eliminates the risk of propeller damage on submerged obstructions, making this unit ideal for rivers and areas with submerged debris. The jet drive system delivers approximately 80hp at the pump, translating engine power into effective thrust for shallow-draft vessels. A 16-valve cylinder head design enhances airflow and combustion efficiency, contributing to improved power delivery and responsiveness.

Phaze Five anti-corrosive paint system provides comprehensive protection against saltwater corrosion and environmental degradation. A freshwater flush device facilitates convenient engine flushing after operation in saltwater, supporting extended service life. Long tube intake tracks enhance airflow and volumetric efficiency for improved throttle response.

The integrated power trim & tilt system allows for quick adjustment of engine angle, optimizing running attitude under varying load and water conditions. An electric starter system ensures reliable engine ignition in all operating environments. With a dry weight of approximately 377 pounds, this outboard balances thrust output with manageable installation requirements.

Finished in white, this outboard complements a variety of hull colors and exterior styling preferences. This engine is backed by the manufacturer’s limited warranty, subject to the terms and conditions specified by the manufacturer. Intended for use on registered watercraft, this propulsion system is suitable for recreational boating in shallow and obstacle-rich waterways.

Key technical characteristics include four-stroke architecture, electronic fuel injection, and jet drive propulsion. Professional installation by a qualified marine technician is recommended to ensure proper alignment, rigging, and calibration for optimal performance and service life. This product is classified as a marine propulsion engine and is intended for use on registered watercraft in compliance with applicable maritime and environmental regulations.
