Yamaha Outboard – F115JB (Jet Drive)

25-Inch Shaft Equivalent | Remote Control | Electric Start | Power Trim & Tilt | Jet Pump | Gray

The Yamaha F115JB swaps the traditional propeller for a jet pump, opening up water that prop-driven boats simply can’t reach. Built on Yamaha’s 1.8L inline four-cylinder engine, this jet-drive version delivers impressive thrust, strong acceleration, and the kind of shallow-water capability that makes it popular with river anglers, hunters, and boaters navigating rocky or debris-filled areas.

If your boating takes you into skinny water or into places where a prop won’t survive the F115JB is built for exactly that.

Key Features:

•  1.8L Inline 4-Cylinder Engine- Quiet, efficient, and dependable in varied conditions.
•  Jet Pump Propulsion System- No exposed prop or gearcase, ideal for extremely shallow rivers and flats.
•  Shallow-Water Versatility- Lets you access areas that would damage a standard lower unit.
•  25-Inch Shaft Equivalent- Mounts on a 25″ transom even though the propulsion method is different.
•  Remote Control Operation- Compatible with Yamaha mechanical or digital rigging.
•  Electric Start + Power Trim & Tilt- Easy ignition and smooth trim control.
•  Corrosion-Resistant Build- YDC-30 alloy and protective coatings help it last in fresh or saltwater.
•  Command Link® Compatible- Works with Yamaha digital gauges and displays.
•  Dry Weight: Approx. 377 lbs- Light for a jet-drive unit of this class.

Frequently Asked Questions

Q: Is it compatible with digital controls?

A: Yes. It works with Yamaha’s Command Link® system.

Q: Does it require a propeller?

A: No. The jet pump handles propulsion. Rigging components are still sold separately.
