ProCharger Supercharger Systems For EFI/MPI Engines
 The ProCharger Advantage
Nothing Else Even Comes Close!
Accessible Technologies was the first to introduce the tremendous benefits of intercooled centrifugal supercharging to the marine market, over 4 years before others, and has become the proven leader in marine supercharging. ProCharger Marine systems offer absolutely unparalleled performance and reliability for the extremely demanding marine environment. As you may know, ProCharger is now available as OEM equipment from many of the leading performance boat manufacturers, and Accessible Technologies now produces more supercharger systems to fit Mercruiser-equipped boats than any other supercharger company.

Identifying Your Model Year
*Please replace "NN" in part number with the model year of your motor (not your boat, they may be different). 1998-2001 model years can be identified by a serpentine accessory belt, while 1994-97 Magnum MPI/EFI's will have "v-belt" type accessory belts. Additionally, 1997-2001 motors have the "Cool Fuel" system with no mechanical fuel pump, while 1994-96 motors have a mechanical fuel pump in addition to the electric pump.
