The all-new Yamaha 90-horsepower In-Line Four V MAX SHO® may be the smallest in the V MAX SHO® line, but it packs the biggest punch of any 90-horse on the water. Its SOHC four-valve-per-cylinder design minimizes weight while optimizing combustion. In fact, its lightweight design combined with 1.8L displacement makes the I-4 V MAX SHO® 90 the class leader in torque and top speed. Add to that the option of a 25-inch shaft and the VF90 is an exciting new prospect for bass, walleye, inshore and muskie anglers trolling on 25-inch transom multi-species boats. The all-new Yamaha I-4 V MAX SHO® 90. A quick, little addition to our V MAX SHO family—and a day out fishing.
The all-new I-4 V MAX SHO 90 is not only the fastest on the water; it’s also the quietest. In fact, it’s noticeably quieter than its closest competitor. It gets even smoother and quieter still when you add a Yamaha propeller with our patented Shift Dampener System (SDS™). Talk about stealthy fishing.
The I-4 V MAX SHO 90 features a single overhead camshaft with four valves per cylinder, for 16 total valves. (Its primary competitor only features eight valves.) This optimizes engine combustion, and creates class-leading torque and acceleration, all while reducing mass in the cylinder head and streamlining weight.
With 1.8L displacement in a light, 353-pound design, the V MAX SHO 90 leads its class in top speed and torque. *Testing conducted by Yamaha at Yamaha’s US Test Facility on a G3 Eagle Talon™ under the same conditions and with each rigged for maximum performance.
In testing, the all-new I-4 V MAX SHO 90 was shown to be noticeably quieter than its closest competitor.* It gets even quieter when you add a Yamaha propeller with our patented Shift Dampener System. *Testing conducted by Yamaha at Yamaha’s US Test Facility on a G3 Eagle Talon™ under the same conditions and with each rigged for maximum 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.
The new I-4 V MAX SHO 90 is California Air Resources Board (C.A.R.B.) Three-Star Rated for Ultra-Low Emissions. This also meets federal EPA requirements.
TCI Microcomputer Ignition monitors throttle position, engine speed and atmospheric conditions in order to precisely adjust ignition timing under all conditions for optimum ignition performance, ensuring smooth and reliable operation.
The V MAX SHO 90 features a three-phase alternator that produces up to 35 amps. That’s plenty of power for battery charging and accessories, with more to spare.
The V MAX SHO 90 offers a 25-inch shaft option, making it a great choice for walleye, bass, inshore and muskie anglers with 25-inch-transom, multi-species boats. It’s also compatible with propellers featuring our Shift Dampening System (SDS™)—for quieter fishing.
Features Yamaha’s Variable Trolling RPM Switch (VTS®), which allows for precision adjustment of trolling speeds from 550 to 1000 RPM in 50-RPM increments, and even trolling at 200 RPM below idle.
A Freshwater Flush Device allows you to flush the engine without starting it, for maximum convenience, durability and engine life.
Yamaha’s award-winning Multi-Function Tiller Handle incorporates engine start/stop, emergency stop, gear shift, power trim and tilt operation, variable trolling switch, warning and controls all in one. It can be added as an accessory to the I-4 V MAX SHO 90.
The I-4 V MAX SHO 90 is compatible with Yamaha’s Command Link® 6Y8 and 6YC digital gauges. It’s also compatible with Yamaha Customer Outboard Protection (Y-COP®), the Yamaha theft-deterrent system.
Use of a gateway device allows certain engine and boat data to be displayed on NMEA-2000® compatible displays that are external to the Yamaha system. For the I-4 V MAX SHO 90, this works with Command Link®.
The I-4 V MAX SHO 90 is equipped with a single compact, lightweight Power Trim and Tilt (PTT) unit. The tilt angle can be adjusted with the optional tilt limiter.
The I-4 V MAX SHO 90 is compatible with Y-COP®, the Yamaha theft-deterrent system. This optional security feature disables the ignition system via an operator-controlled key FOB.
Yamaha’s Mounting System helps reduce vibration by spreading the motor mounts as far apart as possible, both horizontally and vertically. Together with specially designed, rubber motor mounts, it helps to lessen the amount of vibration that is transmitted to the boat.
The I-4 V MAX SHO 90 is compatible Yamaha’s Talon® SDS™ propellers. SDS is our patented Shift Dampener System, and it absorbs the force and noise associated with shifting, for a smoother, quieter ride.
The I-4 V MAX SHO 90 uses a pressurized oil delivery system and incorporates a compact and durable oil pump to keep all of the moving parts of the SOHC system lubricated and running smoothly for maximum reliability.
The All-New VF90 In-Line Four V MAX SHO. A single-overhead-camshaft design with four valves per cylinder and 1.8-liter displacement make the I-4 V MAX SHO 90 a class leader in torque, top speed and efficiency. But it’s not only the fastest—it’s the quietest, too.* That makes for some pretty stealthy fishing. Available for mechanical remote or tiller control.
*Testing conducted by Yamaha at Yamaha’s US Test Facility on a G3 Eagle Talon™ under the same conditions and with each rigged for maximum performance.
*Weight refers to shortest shaft length, and is measured without motor oil, gearcase oil and propeller (except models 25 hp and under, which include a standard propeller). All Jet model weights include the jet pump assembly (weight estimated).
