Want big top end speed, dramatically improved cruising speeds and ability to plane faster? How about not having to sacrifice reliability, durability and idle? What about ultimate bragging rights to owning one of the most incredible looking and technologically advanced marine engines? Sound to good to be true? Well its not, Whipple has the supercharger system for you. The Whipple 525HP EFI SC System will give you all the torque and horsepower your heart desires. With 7psi of intercooled boost (stage 1), your power will increase nearly 50%! Stage 2 features the MOAC intercooler and 7.5psi of boost for another 25HP. Skeptics say, “what about idle?” That’s simple, the Whipple twin-screw type supercharger and ECU calibration will allow for your engine to idle consistently, in and out of gear for easy operation.

The looks are only part of the package, the performance will put an ear-to-ear grin on your face. Because of the unique twin-screw SC design, the Whipple Charger can generate full boost at any rpm, just the touch of the throttle and you have instant power. Roll into the throttles and feel the g-forces push you back in your seat while the sound of an F-16 fighter jet comes too life. You’ll turn your once docile boat into a pure adrenaline rush while putting other boats in their place when they “attempt” to run by you.

Other skeptics say, “Well you can’t have low end torque and top-end horsepower!” Yet again, the facts differ, most don’t know that the screw compressor is one of the most efficient superchargers ever built. What does this mean? Massive torque levels that are simply unmatchable while simultaneously producing mind-boggling horsepower. No other supercharger in the world can offer this type of torque down low with the incredible top end horsepower. Who wants to wait for the power when you can have it instantly!

The Whipple system is 100% full compatible with the stock Mercury Motorola PCM555 computer and features enhanced Guardian features for previously unheard of reliability. Whether you have Smartcraft with Vessel View, Race View or other systems such as Garmin, Raymarine and Northstar, your Whipple system is fully compatible.
