Yamaha Marine Group on Tuesday introduced three new outboard models.
Along with an updated version of the F350, the new 5.3-liter F350C, Yamaha also announced new mechanical control versions of its 225- and 250-horsepower 4.2-liter V6 offshore outboards, available as the F250XB in both left and right-hand rotation, and the F225XB in right-hand rotation only.
“Boaters who need mechanical control can now enjoy all of the legendary 4.2-liter V6 offshore benefits,” said Ben Speciale, Yamaha Marine Group president. “These outboards are great repower solutions for boats that don’t need digital electronic control, yet can benefit from Yamaha’s light weight, high efficiency 4.2-liter offshore platform.”
As for the F350C, it now provides five full years of limited warranty coverage.
“The inclusion of five years of limited warranty coverage with the F350C underscores the reliability of the F350,” said Speciale. “We are confident that this benefit for our 5.3-liter V8 customers builds in exceptional value for Yamaha’s most powerful outboard on the market.”
4.2-liter V6 offshore outboards
Yamaha’s 4.2-liter offshore models have big-bore V6 displacement thanks to plasma-fused sleeveless cylinders. This technology increases displacement without enlarging the outer diameter of the cylinder bores, resulting in an outboard with the largest displacement in its class. The technology also contributes to the outboards’ light weight.
An electronically controlled single throttle valve and “Precision Multi-Point Electronic Fuel Injection” make these outboards up to 17 percent more fuel efficient, according to Yamaha.
V6 Offshore mechanicals are more than 50 pounds lighter than the Yamaha 3.3-liter V6s.
Expected availability of Yamaha’s 4.2-liter V6 Mechanicals is late summer 2016.
New F350C graphics are designed to speak to the technology under the cowl: The “V” graphic not only defines the cylinder arrangement, but also denotes the way the engine makes power. The right side of the “V” graphic represents the flatness of the F350C V8 torque curve.
The F350C offers several benefits over other 350-horsepower outboards, the company says:
- Yamaha’s naturally aspirated V8 delivers more power, more smoothly, compared to a supercharged six-cylinder outboard.
- Specific marine design – the 60-degree V8 has four valves per cylinder and double overhead cams
- Variable Camshaft Timing (VCT) optimizes the engine’s torque at low and mid-range rpm
- Sequential multi-point fuel injection. Eight long-intake tracks in the induction system optimize power
- Less internal stress and friction, and lower internal engine pressures and heat build-up
- It runs on 89 octane fuel, while some supercharged engines need 91 octane for maximum performance.
Expected availability of Yamaha’s F350C is late summer 2016.
