Torque, thrust and power. Yamaha’s new V8 engine, in its 375-horsepower version, is a guarantee of a lot of acceleration. Ideal for a sporty boat like the Tempest 38

by Niccolò Volpati

ITS NAME IS REGISTERED AS F375 XTO. It replaces the old 350 hp Yamaha V8 and promises even more sporty levels of performance. We tried it at Andora, on the Ligurian coast, where there was no lack of wind or waves; the perfect conditions to try out a hull, but a bit less to push a pair of 375 hp beasts. Nevertheless, it’s a common situation. You can feel the push from the engines, even at low rev levels. When I tried out the acceleration to reach planning and top speed, they felt even stronger. Just two and a half seconds to get the hull out of the water, and less than seventeen to get to top speed. With the sea conditions that we found, we capped the top speed we felt we could get to at 44.5 knots. The engines were doing 5200 rpm, and there were still a further 800 before reaching maximum revs.

But the positive characteristics of this outboard engine are not limited to torque and power, there is also its handling. Like the 425-horsepower version, it is also fitted with integrated electronic steering. This increases the weight of the engine a bit, but it definitely makes it easier to use. There is no comparison and that is a good thing for engines of this power. The integrated steering of the outboards is similar to the rotating stern drives on the Volvo Penta IPS. The same feeling of easy control, both when under way, and also when manoeuvring. And it is no coincidence that the outboards are now also fitted with joysticks. The 375 hp version has one, although this is an optional of course. But all the rest comes as standard, from the automatic trim to the seven-inch display with engine and navigation data, and – if you want them – map readings.

As well as the feelings, there are the figures. What really strikes you is the low fuel consumption, both in terms of spot readings, and for the litres per mile usage. A total of two litres per mile, for both engines, are needed to get to planning. And even when you open the throttle right up, you move gradually up to three, and then to four and even when you get to over forty knots do you end up doing more than five litres per nautical mile. So essentially just two and a half litres for each of the two motors. For slower cruising speeds, it will be enough to see how much it uses at 25 knots: three litres per mile, and 68 litres per hour for both engines. The boat’s hull has a lot to do with these good performance figures. It behaves very well on the waves, even when it doesn’t take them head on. It doesn’t feel insecure on them, not even when they are a metre high. At 44.5 knots, however, we decided that we had seen enough.

The area in the bows features a large C-shaped sofa. You can change it into a sunbathing area of up to 2.5 square metres with the use of a collapsible hydraulic table. 

The Tempest 38 was always glued to the water, but it has a distinctly sporty nature. The beam isn’t huge and so if you don’t take the waves as well as possible, you could lose control. It is better not to take risks, and we could feel happy knowing that we have pushed the two Yamahas to 5200 rpm. It was a cross sea, between waves generated by the Scirocco wind from previous days, and the wind that was blowing from the North.

The pair of 375s isn’t the top amount that you can fit. The transom can take a total amount of as much as 850 horsepower. But I think that the power that we tried is more than enough. With the kind of thrust produced, it already has very sporty performance with two 375s. You don’t feel the need to add extra horsepower. The range between the minimum and maximum planning speed is around thirty knots, so you can choose the best speed for any situation.  

Engine data
The F375 by Yamaha has the same engine block as the 425. It has eight cylinders in a V configuration, and 5.6 litre capacity with direct injection. Nearly everything comes as standard, from the integrated electronic steering system to the automatic trim. The only optional is the joystick.
