Description
EFI/MPI – MerCruiser
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, and are available for both EFI/MPI and carbureted applications.
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.
ProCharger Marine systems are thoroughly evaluated through both performance and longevity testing during design, both on the dyno and in the water. Once in production, bench testing and quality assurance for individual components is performed prior to shipment. To help ensure that ProCharger Marine products are the best available, ATI has invested in the industry’s most powerful supercharger test cell, as well as a 1,600 hp dynometer and the largest company-owned fleet of test boats in the industry.
