2025 Yamaha Outboards Jet Drive 90 hp

Shallows. 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 completely redesigned, 1.8-liter F90 Jet Drive outboard produces 65 hp at the pump. Its compact, lightweight SOHC four-cylinder, in-line design features a long-track induction system and Yamaha’s proprietary YDC-30 aluminum alloy. This creates a light, compact, powerful outboard for deck boats and deep-V hulls navigating shallow, rocky rivers, flats and sandbars.

• 354 pounds (including jet pump assembly)

• Fits 25-inch transom boats

• Solid 35-amp alternator

• Power Trim & Tilt

Power and Performance

Precision Multi-Point Electronic Fuel Injection delivers the exact amount of fuel needed for optimum performance and efficiency. Yamaha’s EFI optimizes fuel atomization further enhancing fuel economy.

Single or Double Overhead Camshaft platforms provide lighter weight, impressive acceleration and better fuel efficiency.

Microcomputer Ignition adjusts timing to maintain optimum engine performance, economy and power under all conditions.

Convenience and Control

With no gearcase or propeller extending below the hull, a jet drive allows you to maneuver around or pass over obstructions that would limit the travel of a conventional, propped outboard.

Yamaha’s award-winning, Multi-Function Tiller Handle (optional on F115, F90, F60 and F40 jet models) features an ergonomic design for easy shifting , better grip and less rotation from idle to wide-open throttle. This reduces operator fatigue for a full day of enjoyable boating. Truly multi-function, it control features include throttle, throttle friction control, shift lever, key switch, stop switch and a Power Trim & Tilt switch.

A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
