What are your thoughts on this engine, has anyone tried one out yet?
I am considering one to replace my 2004 Mercury 25HP 2-Stroke on my Custom Gheenoe with center console.
At 126 pounds the new engine would only be 12 pounds heavier than my current 2-stroke and can include power trim among a list of seemingly great features.

From the Yamaha site below:
THE REDESIGNED F25
Completely reinvented, the all-new Yamaha F25 is the lightest 25-horsepower outboard on the water—two stroke or four stroke. In fact, it’s SOHC 2-cylinder design creates a power-to-weight that’s not only class-leading; it’s category-jumping, taking on Portable performance advantages. Once that sinks in, you’ll realize it means 25 horses can boldly go where they’ve never gone before. Jons. 14-foot aluminum fishing boats. The bed of your truck. While its streamlined design is up to 25 percent lighter, it still manages to pack in exciting new features—like battery-less EFI and an optional electric start kit. The completely reimagined Yamaha F25 Portable four stroke. It’s one of the most exciting outboards to hit the water in years.
BATTERY-LESS EFI
The F25's electronic fuel injection system provides smooth running and greater fuel efficiency than the previous F25. And the system operates without a battery, thus reducing weight so if you want to go light, you can. The New F25’s battery-less system was designed to require minimal effort for manual starting through an auto decompression device and a short pull. (A battery is required for electric-start capability.
QUICKER THAN TWO-STROKE
The new F25C outperforms the traditional Yamaha 25-horsepower two stroke. So it’s the perfect power for 14- to 16-foot aluminum boats and similar craft.*
*Testing conducted by Yamaha at Yamaha’s US Test Facility on a G3 Model 1448 under heavy load conditions.
OVERALL PERFORMANCE
The F25’s SOHC, 2-cylinder design, optimally balanced crankshaft and labyrinth exhaust deliver smooth power, and its Microcomputer Ignition adjusts timing to maintain optimal engine performance, economy and power under all conditions.
