Yamaha F-350

A domesticated monster

Fueraborda V8 of four times and 350 CB equipped with more the outpost mechanical and electronic technology. A monstrous push in all the curve of revolutions and quieter and elastic sensations. We know as he is fueraborda more powerful of the world.

Oía to be spoken of him months ago, and was let see the past for the first time during hall Miami. Finally already it is here! A perfect motor for central console boats or stroll or walkaround, deep-sea fishing from the 30 either 40 feet or even the more double or triple motorization. Every time more boats thought about motorizations are designed and made fuerabordas of high power. These motors offer important advantages against them intrahut of equivalent powers as they are the maintenance facility, installation, hibernaje, saving of space, change of helices, ......

The F350 is fueraborda more powerful of the world with its 350 CB and a weight of 365 kilos, that is to say one relation of almost a kilo of weight by each horsepower (1.04 Kg/CV).

It extremely supposes an interesting option in boats that normally are motorized with 2 fuerabordas of 150 or 200 CB each, since it obtains an important improvement of weight as well as a simplified installation and maintenances.

If we exactly compared with an installation of 2x150cv the tests they give like result a little more speed end. For example in a Grady 25,7 (stroll the USA fishes) with the new F350 maximum speed GPS was of 51 knots in front of 47 knots with 2x150cv. A little more speed end as a result of increases of power (350 CB versus 300 CB). The acceleration in both cases is electrizante with 6.5 seconds to happen of 0 to 30 knots.

The consumptions measured in tests realized in the USA are of 1.6 Miles by Gallon (a gallon is equivalent to 4.7 liters) at terminal velocity, and of 2.6 Miles/3,500 Gallon to RPMs, Really the new F350 offers more power, majors speeds end and equivalent consumptions compared with a double fueraborda of 2 150 xs CB.  

But the advantages do not finish here, since the sonorous level net has been improved against the previous example, reducing of 98 dBa to 93 dBa to power top. All this is the fruit of many improvements…  Altogether up to 600 new components in this new motor!

We also compared if it against 250 CB of 4 times, the new F350 generates a 45% more of push and still more in the losses and averages revolutions thanks to the advance of variable ignition (variable camshaft timing) controlled of digital form, thanks to the new multi-point injection, or to system VCT of variable opening of the valves.

Even with the boat to 30 knots, when pushing the thorough throttle we will feel a true kick in the buttock until reaching the terminal velocity.

In front of its more direct competitors in power as they are it 300 Suzuki or the Mercury, we appreciated that the traditional throttle has been replaced by a new one that is connected to the motor by means of a simple electrical cable. That is to say, the flow management acts generating a signal electronic that it arrives at the motor by a cable of DS, which is in charge to control the system of injectors.

The assembly is simplified of evident form. Of the throttle a cable to a small “HUB” similar to the one of the networks of computers is connected, and from this concentrator it naturally leaves another cable to the digital instruments and another one to the motor.

Any extension of the “used architecture” in the assembly, like for example the screen chart additional plotter or clocks, is connected to this “HUB” that acts like concentrator of the DS.

The hardness of the handle can be modified by the user from practically zero effort to a suitable hardness that will avoid “frights” when beating I jump too great in a wave and with formed sea.

In case of multiple motorizations the F350 “is understood to each other” to synchronize itself in revolutions and to push always the same regime, being obtained a symmetrical push and totally balanced. 

The F350 nevertheless does not come preparation from series with attended direction electrohydraulic which forces with double facilities to mount one of the available ones in the market. 

In facilities of a single motor the significant weight of fueraborda gives like result a hard government, which in the end can suppose a security extra, since CB with an excessively smooth steering wheel is not nothing recommendable to handle 350.

The new F350 de Yamaha possibly marks a new one was in the motors fueraborda and in which they emphasize the important advances in his technology. Yamaha without doubt establishes a new standard in the benefits and the efficiency of motors fueraborda with characteristics truly “offshore”.
