New Yamaha 4-Stroke 25-hp Engines

Yamaha’s new F25 and T25 (High-Thrust) outboard engines are easy to start and sip fuel, and have a 3-year limited warranty for pleasure use.

Last week Yamaha made the official introduction of two new outboard engines, the
F25 and the T25. Both are 4-stroke, carbureted CARB 3-Star emission-compliant motors
which are available with 15” and 20” shafts. The Yamaha T25 is the “High-Thrust”
version which features the company’s "Dual Thrust” prop and a larger lower unit
with a 2.42:1 reduction gear rather than the 2.08:1 on the F25 model. This engine
was designed for heavy loads such as small pontoon boats, sailboats, and work
boats. We found the F25 we tested easy to start, quiet and remarkably fuel efficient. Yamaha
tells us that
they have found the new engines are from 25% to 32% more fuel efficient
at best cruise than their 2-stroke 25-hp motors.
We wrung out the new engine in a video test, so find out all about it --
