E - 3 ENGINE & DRIVE SYSTEM
A. Engine
The 358 Vista
®
model is equipped with twin engine
propulsion. Depending on which model either stern
drive or inboard, a choice of Mercruiser
®
, Crusader
®
or Volvo-Penta
®
engines are offered. Please consult
the engine owner’s manual provided with this manual
for operation and maintenance information. See your
Four Winns dealer for complete engine availability.
B. Stern Drive
A stern drive or inboard/outboard propulsion system
has a piston engine equipped with special marine
components mounted near the transom and coupled
to an external outdrive-type transmission unit. Shifting
is performed within the outdrive upper gear case.
This type of system is depicted in Figure E-1.
Figure E-1: Stern Drive
Consult the Engine Owner’s manual for additional
informa tion on stern drives.
C. Inboard V-drives
On the V-drive propulsion system of the inboards, all
shifting and gearing components are installed inside
of the hull, only the propeller shafts and associated
equipment are under water. The V-drive system has
the en gine mounted in the extreme stern of the boat
with the out put shaft facing forward. A transmis sion
which performs shifting functions is mounted di rectly
onto the engine. A V-drive reduction gearbox is
mounted di rectly to the transmission. The prop shaft
is then con nected to the V-drive output coupling.
See Figure E-2.

NOTICE
Always return the engine throttle lever to the
extreme low speed position before shifting.
NEVER shift the unit while engine speed is
above 800 rpm.
E - 4 UNDERWATER EQUIPMENT
(Inboards)
Avoid run ning aground or striking a
(submerged) object. Serious damage to the
engine(s) or inboard underwater gear can
result and the boat can take on water. In the
event of such an occurrence, proceed at low
speed to the nearest service facility and have
an immediate inspection made of the prop
shafts and struts before further use of the craft.
Keep all life saving devices at hand while
driving to a dock area. If the boat cannot be
immediately removed from the water,
thoroughly inspect the bilge area for leaks
so that the boat does not sink while moored.
A. Shaft Log
The shaft log allows the propeller shaft to extend and
rotate through the hull with only limited water leakage
occurring. Minor dripping may occur and is not
abnormal during operation. See Figure E-2 & E-3.
