2025 Yamaha Marine Jet Drive 90 HP

JET DRIVE

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
  • Power Trim & Tilt
