Yamaha Marine Group today introduced its next-generation F90 and F25 four-stroke outboards. The engines are debuting at the Minneapolis Boat Show, which opens today.
With the new F90, Yamaha has also introduced a new F75 in the same engine family. The F90 is lighter and quicker than its predecessor, Yamaha said.
“The improvements made to the new Yamaha F90 and F75 make them terrific choices for a variety of boats, particularly for the inshore fisherman,” Yamaha Marine Group Ben Speciale said in a statement. “It has the quickest four-stroke 90-hp acceleration available — period.”
At 353 pounds, the F90 is 13 pounds lighter than the previous F90, which was introduced in 2005, and displaces 1.8 liters, versus 1.6 liters.
“It’s a real gutsy engine, with a single overhead cam driving four valves per cylinder,” David Meeler, Yamaha information manager, told Trade Only. “We’re really excited about this engine and how powerful it is for its size and weight. When you punch the throttle, you’ll be hard-pressed to believe it’s a 90-hp.”
The F90 is not just quicker, it’s also quieter, said Yamaha. The outboards can be paired with several Yamaha propellers with the Shift Dampener System, including Talon propellers.
The F90 and F75 are compatible with Yamaha’s Variable Trolling RPM Switch for slow trolling. They can be rigged for use with Yamaha's tiller handle. The engine has improved charging capability, with 35 amps of power, compared with the previous 25 amps.
Yamaha said the new F25 weighs less than 126 pounds, making it the lightest 25-hp model in the industry.
“The new F25 is 25 percent lighter than its predecessor, comes packed with powerful benefits and even outperforms the traditional Yamaha 25-horsepower two-stroke,” Speciale said in a statement. “It is the perfect power solution for 14- to 16-foot aluminum boats, as well as many other craft.”
“The boaters in the Midwest have been asking for a new 25 for a long time now,” Yamaha Marine Group communications manager Martin Peters told Trade Only. “Minneapolis was a fitting venue for the launch.”
This two-cylinder engine has a weight range from 126 to 143 pounds (depending on shaft length and model), compared with 168 to 181 pounds for its predecessor (which was introduced in 2009). The F25 is a battery-less electronic fuel-injected engine, which means its fuel injection system and its ignition system kick in during pull starting, said Meeler.
This engine also has the Variable Trolling RPM Switch. The F25 has improved, built-in carrying handles, and the tiller handle has been updated for easier use.
The engine also is resting-pad-equipped on two sides. The external oil draining system offers easy maintenance for the dealer or consumer, said Yamaha. An electric starting kit is available as a field upgrade.
