Description
The Yamaha F90JB is a 90hp Jet Drive four-stroke outboard (65hp at the pump) with remote mechanical controls, electric start, power trim and tilt, and a 25" extra long shaft, weighing 354 lbs. Built for river boats, deck boats and deep-V hulls running shallow, rocky rivers. As an authorized Yamaha dealer, Boat Specialists sells it new with the full Yamaha 2-year factory warranty, after our factory-qualified technicians test-run it.
Yamaha's Jet Drive outboards go where propeller-driven motors can't: shallows, shoals, rocky-bottom rivers and rapids, with no prop to break on rocks or other underwater obstructions. The redesigned 1.8-liter F90 Jet is a SOHC four-cylinder that produces 65hp at the pump, built with Yamaha's YDC-30 aluminum alloy for a light, compact motor.
Yamaha F90JB Key Features
Incredible Maneuverability: 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.
Easy Engine Flushing: A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
Reliability and Durability: Combined with our proprietary alloy (YDC-30), Yamaha's exclusive Phaze Five™ anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha Jet Drive four stroke outboards.
REQUIRED FEE
$410 Dealer Engine Prep - Our factory-qualified technicians perform a full test run of your new outboard by unpacking it and connecting it to the rigging, fuel, battery, and a diagnostic computer. We run the motor up to operating temperature and test every function to make sure your new motor is working just as it should. The manufacturer's required inspection checklist is completed and submitted to the manufacturer to validate the warranty.
Yamaha F90JB FAQ
What size boat is the Yamaha F90JB for?
Built for river boats, deck boats and deep-V hulls running shallow, rocky rivers. Always check your boat's capacity plate for its maximum horsepower and weight.
Do I need a short or long shaft?
Measure your transom from the top edge straight down to the bottom of the hull: about 15" calls for a short shaft, 20" for a long shaft, 25" for an extra-long shaft, and 30" for an ultra-long shaft. The F90JB has a 25" extra long shaft. Not sure? Call or text us at (805) 644-6290 and we'll help you choose.
What comes with the F90JB?
Standard features and included items: power trim & tilt, jet lower unit, steering link arm, and owner's manual.
What do I need to buy separately?
Any controls, gauges or rigging your boat needs are sold separately. We can help you pick the right parts, and our team can rig it for you.
What warranty does it come with?
It's covered by the full Yamaha 2-year warranty. See our Brand Warranties page for details, and ask about extended warranties.
Do you offer financing?
Yes. Financing is available on new outboards. See our Financing page to learn more and apply online, or call or text (805) 644-6290.
