26 Innovatief en vederlicht Yamaha F350 V6 Standnr: Y This spring, Yamaha introduced the new F350 V6 outboard engine. This V6 was developed from the well-known 300-hp V6 block. But Yamaha would not be Yamaha if there were not a lot of innovations incorporated into this engine. Boat testing tried out the brand new Yamaha F350 in La Spezia (Italy). Exponential The predecessor of the new F350, the Yamaha F350 C was a 5.7-liter V8 engine introduced in 2016. The first (A) type of this model entered the market back in 2007 and at the time was the very first 350hp and thus the strongest outboard in the world. Between 2013 and 2023, sales of engines around 250- 350hp increased by 400%. This is because many inboard gasoline and diesel engines are being replaced by modern, powerful outboards. These are more compact, lighter, cheaper and easier to maintain. Large block The Yamaha F 350 has a large 4.3-liter V6 block with two rows of three cylinders at a 60-degree angle. They have dual overhead camshafts and variable valve timing. It is clever that the Japanese can get 350 horsepower out of a six-cylinder weighing only 293 pounds. This Yamaha F350 is by far the lightest in its class. That’s partly because the cylinder walls have been treated with a plasma spray coating that reduces resistance by 60 percent. This eliminates the need for steel piston liners. Piston travel has also been increased so that the engine’s cylinders deliver great torque even at low rpm. Thanks to the larger gas intake valve from the 450hp Yamaha XTO, a larger air-fuel mixture reaches the engine. Innovative Of course, this new F350 has the integrated Yamaha steering system. With this, the electric motor inside the hood digitally directs the unit in the right direction, eliminating the need for an external steering cylinder. The system works perfectly, steering feather light and precise. Downright spectacular is the pairing of the F350 with the Helm Master EX system with autopilot and the -in-that-system-integrated bow thruster. The Helm Master EX bow thruster integration is especially useful on single installations. With it, a boat with single engine can be controlled flawlessly with the joystick and even moved sideways. It is nice for first-time water sports enthusiasts to be able to maneuver perfectly after 15 minutes of practice with this system.
