VOLVO PENTA AQUAMATIC

5.7GXi/SX
8-cylinder, 4-stroke, gasoline marine engine
235 kW (315 hp)

Engine 5.7GXi with SX

The 5.7 liter GXi is a GM Vortec Aquamatic drive
gasoline engine in a V-8 configura-
tion featuring: seawater cooling with
cast iron cylinder block, cylinder
heads and exhaust manifolds, which
are specially developed for the ma-
rine industry. The exhaust manifolds
and risers are EDP treated for in-
creased durability. In addition, the
seawater pump is located on the
front of the engine for easy accessi-
bility.
Fuel injection
The TBI system is monitored by an
Eletronic Control Module (ECM) and
gives the following advantages: more
