2025 Yamaha Marine Jet Drive 115 HP
JET DRIVEShallows. Rocky-bottom rivers. Shoals. White-water rapids. They’d all prove treacherous for a propeller-driven outboard, but Yamaha’s Jet Drive outboards are all about it. Available in 150, 115, 60 and 40 horsepower, you can “off-road” without the possibility of breaking a blade on rocks or other underwater obstructions. So, while you may be giving up the prop, you’re gaining a whole lot of freedom with a jet drive.
Our 1.8-liter F115 Jet Drive outboard produces 80 hp at the pump. Its compact, lightweight DOHC design features 16 valves with four valves per cylinder and long tube intake tracks. This produces ample power for deck boats and deep-V hulls navigating shallow, rocky rivers.
Features may include:
- 377 pounds (including jet pump assembly)
- Fits 25-inch transom boats
- Solid 35-amp alternator
- Power Trim & Tilt
