ProCharger Supercharger Systems For Carbureted Engines

procharger logoThe 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.

MerCruiser 454/502 Magnum (Carbureted)
M1 Intercooled 12 rib

454 and 502 Magnum engines are excellent candidates for supercharging. This is due not only to a moderate compression ratio, but also very rugged components: forged pistons, a steel crank, and a four bolt main.

With an Intercooled ProCharger system, there is no need for internal engine modifications prior to supercharging, and power gains of 45-65% are typical with stock motors running pump gas. Aftermarket parts are also plentiful, and for modified applications, power gains can safely exceed 100% with operation on pump gas*. ATI has safely produced over 1,200 hp on modified Magnum and similar motors.

ProCharger
MerCruiser 7.4 (carbureted)
dual Carburetor M-4

Although a poor candidate for roots supercharging due to the heat produced from roots blowers, 7.4 motors are excellent candidates for Intercooled ProCharger systems, producing large percentage gains with low boost levels. Although these are lower compression motors, intercooling is mandatory due to the use of cast pistons in stock 7.4's. The cast crank and 2 bolt main is sufficient for over 600 hp, but ATI recommends maintaining the factory redline for maximum longevity.

There is no need for internal engine modifications prior to installing an Intercooled ProCharger, and power gains of 45-55% are typical with stock 7.4's running pump gas.

ProCharger
MerCruiser 350 Mag and 5.7 (carbureted)
M1 Intercooled 12 rib

Due to higher compression, only intercooled systems are recommended for stock 350/5.7 motors. With an Intercooled Procharger system, there is no need for internal engine modifications prior to supercharging, and power gains of 45-55% are typical with stock motors running pump gas.

ProCharger
MerCruiser HP 500 and older HP motors (carbureted)
MerCruiser HP 500

HP motors are Mercury's most rugged motors, and are excellent candidates for supercharging. With an intercooled ProCharger system, there is no need for internal engine modifications prior to supercharging, and power gains of 45-65% are typical with stock motors running pump gas.

With lightly modified HP and similar motors, ATI has produced over 1,200 hp with an M-4 ProCharger (still covered by a 1-year warranty), with power gains exceeding 110% while operating on pump gas.
