Overview Yamaha 115hp Jet Outboard F115JB

The Yamaha 115hp Jet Outboard F115JB opens up waterways that traditional propeller-driven outboards simply can’t reach. Designed with a jet lower unit instead of a prop, this outboard allows boaters to navigate shallow rivers, rocky bottoms, and fast-moving water with confidence.

Powered by a 1.8-liter DOHC four-cylinder engine with Electronic Fuel Injection, the F115JB delivers smooth, efficient power while producing 80hp at the pump—ideal for deck boats and deep-V hulls operating in challenging environments.

Jet Drive System – Prop-free design enables safe operation in shallow and debris-filled waters
1.8L DOHC Four-Stroke Engine – Delivers strong torque and smooth acceleration with efficient fuel use
Electronic Fuel Injection (EFI) – Reliable starts, optimized fuel delivery, and reduced emissions
Exceptional Maneuverability – No gearcase below the hull for improved handling and obstacle avoidance
Freshwater Flush Device – Flush the engine without starting it for easier maintenance and longer engine life
Phaze Five™ Anti-Corrosion Protection – Five-layer paint system with YDC-30 alloy for superior durability
Power Trim & Tilt – Enhanced control in varying water depths and loading conditions

Why You Should Buy it

If your boating takes you into shallow rivers, rocky channels, or areas where props are at risk, the Yamaha F115JB is the ideal solution. It trades a propeller for freedom—giving you access to waters others can’t reach, without sacrificing Yamaha reliability, fuel efficiency, or performance.

FAQ

Frequently Asked Questions About Yamaha 115hp Jet Outboard F115JB

Why choose the jet version of Yamaha 115hp Jet Outboard F115JB?

The Yamaha 115hp Jet Outboard F115JB is configured around jet propulsion rather than an exposed propeller, which is why the row highlights 80 hp jet output and a 1.8 L four-cylinder four-stroke engine with Electronic Fuel Injection (EFI). That gives the motor a very different use case from a standard lower-unit outboard.

Where does this outboard fit best on the water?

This jet outboard is described for shallow, rocky, and obstacle-filled waters where prop-driven outboards can’t operate. The jet-drive configuration, EFI layout, and 25" (Extra-Long) shaft length make the shallow-water emphasis clear from the first line of the product copy.

What engine setup does this outboard use?

At its core, this jet outboard uses a 1.8 L four-cylinder four-stroke engine with Electronic Fuel Injection (EFI), but the row also states 80 hp jet output instead of quoting only a propeller-style rating. That gives buyers a clearer picture of how the jet setup is being presented.

How do the starting and trim systems affect day-to-day use?

The row combines a 25" (Extra-Long) shaft, Remote Mechanical steering, and Electric start, which gives buyers a practical snapshot of how this motor is meant to be operated. Between the shaft length, steering style, and starting method, it is easier to separate this version from others in the same horsepower range.
