New F25, F75, and F90 Outboards from Yamaha: Lighter, Faster, Quieter Outboard Motors

new Yamaha F25 outboard.

New outboard engines from Yamaha promise to deliver more power with less weight. The new F90, F75, and F25 outboards are each aimed at anglers and according to Yamaha, offer improved performance and economy with quieter operation. We got a sneak-peek at some of these motors at the Miami International Boat Show, and you can get a glimpse for yourself right now.


This all-new motor features an EFI system that does not require a battery and should improve starting, fuel efficiency and over-all operation compared to the previous F25, which uses a carburetor. The lightest version of the new F25 weighs just 126 pounds, according to Yamaha. That’s a whopping 66 pounds–25 percent–less than the previous F25, and 46 pounds less than the EFI Mercury FourStroke 25.

Offered in 15” and 20” lengths, there are eight variations of the new Yamaha F25 outboard.

The new F25 features a 432cc twin-cylinder powerhead, a little less displacement than the previous 498cc F25. The F25 features the Yamaha variable trolling speed feature, which can be activated with a button on the Multi-Function Tiller Handle, through a Command Link display, or a new remote switch on models with remote controls. The variable speed feature permits adjustment of the engine speed from 750 to 1050 RPM in 50 RPM increments. Alternator output is increased by 14 percent to 16 amps. The new motor has improved carry handles and is more compact than the previous F25.

These new 1.8-liter in-line four-cylinder models will replace the previous 1.6-liter four-cylinder F90 and F75 outboards.




Yamaha’s 1.8-liter powerhead is also used for the F115 models. Despite the 13 percent increase in displacement, Yamaha says weight decreases by 13 pounds, from 366 pounds to 353 pounds. Competing 90 HP outboards range in weight from the 320-pound 1.3-liter Evinrude E-TEC 90 to the 341 pound 1.5-liter Suzuki DF90 to 359 pounds for the 1.5-liter Honda BF90 and the 2.1-liter Mercury FourStroke 90. The 1.7-liter Evinrude E-TEC 90  H.O. weighs 390 pounds.

Yamaha claims more top-end power and bottom-end torque from the new powerhead (compared to the previous 1.6-liter engines), and I would expect an improvement on the bottom just from the increase in displacement. This should help the motor perform better on heavier boats and pontoons. Charging power is also improved, from 25 peak amps to 35 peak amps, with about 28 amps available at just 1000 RPM. The new motors can be equipped with the Yamaha Multi-Function Tiller Handle (sold separately) that incorporates engine start/stop, emergency stop, gear shift, power trim and tilt operation, and a variable trolling switch. Walleye anglers will appreciate that variable trolling speed feature, which can also be activated through a Command Link display or a new remote switch, and permits adjustment of the engine speed from 550 (200 RPM below idle speed) to 1000 RPM in 50 RPM increments. These motors are also compatible with Yamaha Shift Dampener System (SDS) propellers.



Yamaha will now offer its V MAX SHO 115 and V MAX SHO 175 outboard models in a 25” length in addition to the standard 20” shaft. The longer length will fit more pontoon boat applications as well as many deep-transom aluminum fishing boats.

There also a number of new outboards props coming from Yamaha, all featuring the Yamaha Shift Dampener System (SDS) with a special cushioned hub that eliminates the “clunk” sound of the drivetrain take-up when the motor is shifted into gear.

  • Saltwater Series II SDS propellers for Yamaha F200 through F300 V6 outboards feature a large blade area and progressive rake angle to provide great acceleration with excellent load-carrying capacity for large boats, and are available in 17” through 23” pitches as well as 13” and 15” pitch.
  • Reliance Series SDS propellers for Yamaha four-cylinder motors in the F150 through F200 range are available in 13” through 21” pitch, in right- and left-hand rotation.
  • The new Saltwater Series HS4 SDS four-blade propellers are intended for Yamaha 200-to-300 HP four-stroke outboards and when compared to three-blade propellers deliver improved acceleration and low-rpm planing. The Saltwater Series HS4 SDS propellers are available in 21” through 23” pitches, in right- and left-hand rotation.




  • The new Talon Pontoon and Talon GP SDS props for pontoon applications have significantly more blade area for outstanding thrust and reduced ventilation in turns. Talon Pontoon SDS Propellers polished stainless steel. Talon GP SDS propellers are aluminum. Both Talon lines fit Yamaha T50, T60 and F70 through F115 four-stroke engines. They also fit 60 HP through 130 HP two-stroke Yamaha outboards.
