525 EFI (525 HP)
BIG HP GAINS FOR THE LEGENDARY “BLUE MOTOR”!
ProCharger’s proven supercharger system for the Mercury Racing 525 EFI delivers 8 PSI of boost and a 55% increase in power. Featuring the M-1SC supercharger, this kit includes an amazing fuel system with twin pumps, dedicated surge tank and fuel lines, larger injectors, an air-to-water intercooler, and tune for the factory computer. The result is 800+ horsepower and a massive increase in torque across the entire rpm range. That power increase allows a bigger blade for big speed increases, and the increased torque allows for a massive improvement in planing time.
