Based on the V6, Mercury is now developing a range of models from 175 to 225 hp. For the 150 hp, the American manufacturer uses a 3-liter in-line 4-cylinder block. But surprise, Mercury has pulled a 150 hp model out of the hat, based on the 3.4-liter V6! To differentiate it from the "classic 150" that remains in the catalog, this new V6 is called the 150 R. R for racing...
We tested the 150 R, which is also available in a 200hp version under the name 200 R.
The little brother of the Racing range
Mercury's Racing range is available through the traditional dealer network, but reserved for advanced users. This range is really designed for competition boats, with power ratings of 500, 400, 300 and 250 hp, plus 60 hp for F3 and S4 classes. These engines are also available with specific competition bases.
Racing sold in dealerships
The new 150 R has been given the Racing name, and will be distributed through the traditional dealer network. This V6 is in a much wiser slot than its big brothers. In fact, this engine is mapped to deliver plenty of torque on start-up and very rapid acceleration.
We tested it on fresh water on a 6.16 m Bayliner hull weighing 1650 kg with 3 people on board and 130 liters of fuel.
Interesting performance
From 0 to 20 knots is achieved in 4.20 seconds. Top speed at 5750 rpm is 36.25 knots (consumption 50 l/h). At 4000 rpm, we're at 25.75 knots (fuel consumption 26.6 l/h). The best rpm is at 3000 rpm, where the boat does the most miles per liter (1.18 M/l).
The sweet sound of the V6
Last but not least, the inimitable purr of the V6 is very much in evidence. All you have to do to get the most out of it is open the exhaust on a tight curve. For lovers of mechanical engineering, this sound remains a pleasure to the ear!
Electric controls
In terms of accessories, this motor is available with a standard baseplate, but with a slightly different baseplate ratio than the 175. What's more, this engine features electric controls that are really pleasant to use, and offer a truly appreciable level of driving comfort. On the other hand, we regret the absence of electric steering. Instead, a conventional hydraulic cylinder is required.
Aggressive design
Last but not least: the design. The engine cowling is a real success, and it alone makes you want to equip your boat with 150 R. So you can tell your pontoon neighbors that you're sailing in Racing mode!
