Having been behind the steering wheel of Mar.co R-Evolution 36 several times in the past with various engine combinations, I cannot hide that I was surprised but also very curious when I informed that the two new Mercury 600hp engines had been mounted on its transom.
It was obviously an overpowered combination and I was expecting to see how the hull of the R-Evolution 36 Rib would handle the total 1200hp horsepower as well as the huge torque of Mercury's new 7.6L V12 outboard engines.
It may be the first time that these two powerful engines have been installed on such a "small" boat.
It is worth noting that when we tested Mar.co E-motion 36 Cabin with 2 x 450R we were really impressed by the performance and the incredible accelerations. You can see the corresponding test at this link: MAR.CO E-Motion 36 Cabin - 2 x 450R Verados
On the day of our test the big waves may not have allowed us to push the throttles at wide open position so as the engines release all 1200 horsepower of their total power, but we were able to get a very good sense of their operation.
At first it was immediately apparent that even a slight touch of the controls was enough to feel the enormous torque of the engines that made the boat jump forward as if it had no weight at all.
It was obvious that we had in our hands a real rocket that made us hesitant and very careful in its handling.
The general behavior of the engines made us feel excited, but what really impressed from the beginning was their incredibly quiet operation accompanied by the complete absence of vibration. It's really enjoyable to have these engines on your transom.
Also impressive was the absence of that annoying noise that makes us feel a little uncomfortable when using the Smartcraft Joystick. We never heard any clunks as it shifted.
Concerning the acceleration and torque they were really on another level and they offered us an incredible sense of power and throttle response. And of course this is not only due to horsepower and large displacement but mainly to the combination of double propellers and the numerically large gear ratio (2.50: 1) which constitute an explosive combination of torque and thrust.
The dual contra-rotating propellers having a very large total blade surface have increased grip in the water resulting in explosive accelerations and direct planning even in heavier boats fully equipped. They also keep the boat planed at low speeds, offer a huge stern lift and therefore a significant reduction in slip rates with the immediate result of higher cruising speeds and reduced fuel consumption.
We should definitely not miss the innovative and revolutionary applications that raise the bar of competition very high and lead the outboards’ industry to a new era.
First of all, the way the new 600hp Verado turns is unfamiliar for an outboard engine.
Turning the steering wheel, the engine body remains stable and only its lower unit is turning. It’s the first steerable gearcase in the history of outboard engines.
It is characteristic that only from the inclination of the boat did we understand that we were turning since the engines remained stable on the transom. It was really weird when during the turns we looked back and the engines were perpendicular to the transom.
This revolutionary function also provides more usable space to the right and left of the engines so that the swimming platforms can now be constructed wider.
The new powerful engine also features the first two-speed automatic transmission in the outboard industry, maximizing performance in both planning and low rpm as well as acceleration and high speeds. The engine shifts into second gear automatically, dropping the rpm and reduces the fuel consumption.
It is impressive that at no point did we notice the transmission shift which was extremely slight.
Turning 32-inch propellers, Mercury engines got R-Evolution 36 on plane at 2200 rpm with 12.5 knots.
At 3000 rpm we were traveling with 25 knots burning 2.96 liters per nautical mile, while at 3500 rpm we ran at 32 knots consuming 3.03 liters per mile.
At 4000 rpm we were riding with 36 knots consuming 3.1 liters per mile while at 4500 rpm our speed was 42 knots burning equally 3.1 liters per nautical mile.
Unfortunately the weather conditions did not allow us to run faster, while the manufacturer in a previous test recorded 60.5 knots at 6350 rpm with a fuel consumption of 381 liters per hour.
