2002-2009 Mercury Marine 350 Magnum / 350 Black Scorpion Whipple Supercharger System

2002-2009 MERCURY MARINE 350 MAGNUM / 350 BLACK SCORPION
WHIPPLE SUPERCHARGER SYSTEM

The Whipple Supercharger System for compatible 2002-2009 Mercury Marine 350 Magnum and 350 Black Scorpion applications is designed for SmartCraft ECM555 engines with a standard throttle cable. This system is not intended for DTS applications.

This package is designed for customers who want big block-style power and torque from a small block marine engine package without the added weight and fuel economy penalty of a larger engine combination.

Whipple twin-screw supercharger technology delivers instant boost response and broad torque across the RPM range. Because the Whipple twin-screw design can generate boost quickly with throttle input, the 350 Magnum and 350 Black Scorpion platform can deliver stronger low-speed torque, faster planing, improved acceleration, and increased top-end power when the complete setup supports it.

Whipple ECM/PCM calibration support helps manage fuel, spark, and engine protection strategies for the supercharged application while supporting long-term reliability when the engine, fuel system, cooling system, ignition system, and installation are properly matched to the package.
