With a powerful 1.8‑liter inline four-cylinder engine that delivers 65 hp at the pump, this jet drive offers unmatched freedom without the risk of blade damage.
Key benefits include:
- No propeller or gearcase exposed to rocks – glide over sandbars and reefs with confidence.
- Compact and lightweight design (354 lbs) ideal for 25‑inch transom boats and deep‑V hulls.
- Efficient fuel system featuring multi-point electronic injection that maximizes performance while reducing consumption.
- Microcomputer ignition optimizes timing in all conditions, ensuring reliable power delivery.
The engine’s SOHC four-cylinder layout uses a long-track induction and Yamaha‑designed aluminum alloy for durability. It runs on 10% ethanol blends or pure gasoline with an octane rating of at least 87.
Control is simplified through the optional ergonomic multi-function tiller handle, offering throttle, shift lever, key switch, stop switch, and power trim & tilt functions in a single grip to reduce operator fatigue during long outings.

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.
Features may include:
354 pounds (including jet pump assembly)
Fits 25-inch transom boats
Solid 35-amp alternator
