Inboards utilize thru-hull water  intake scoops.  These
types ofintakes have anexternalstrainer.  Besurestrain-
ers are kept free of mud, weeds and other debris. Some
boating areas require that additional strainers or water
intakefiltersbeinstalled.   ReferenceSectionP-3  - Equip-
ment Installation, in this manual for installation instruc-
tions and consult your Four Winns dealer regarding any
special equipment that may be required.
A gate valve or seacock is provided at each engine in-
take scoop previously described. Be sure these valves
are in the open position (lever is parallel with the valve)
when operating the engines and in the closed positions
(lever is perpendicular to valve) when engines are not
operating for an extended period of time.
Figure  E5:   Prop  Installation
Serious  engine  damage   could  result  if
seacock   valve(s)    is  not  open   during
engine(s) operation. Ensure seacock valve(s)
are  in  the  open  position   when  operating
engine(s).
NOTICE
Should it be necessary to change propellers, al-
waysuseanappropriatepropellerremovaltoolor
Prop Puller.” DO NOTattempt removal using a
hammer.  Damage to the propeller or propeller
shaft can result.
Should an engine intake or an exhaust or cool-
ing hose rupture, turn the engine off and close
the seacock immediately. Proceed under tow,
if necessary, to a service facility for appropriate
repairs; maintain a  close visual watch on  the
problem hose and also on the bilge water level.
Always check shaft rotation before propeller installation.
A right hand rotation propeller must be installed on the
prop shaft connected to a starboard engine.  Similarly, a
left hand prop must be connected to the port engine shaft.
The propellers must rotate outboard not inboard.
Be sure the propellers are of the correct blade configura-
tion, diameter, pitch, and shaft size to assure good perfor-
mance.  For  additional information on factors affecting
performanceand/orassistancewithyourselection,please
consult your Four Winns dealer.
Inboard boats utilize exhaust hose to relinquish cooling
water. Aperiodic inspection of the hose, muffler and re-
lated parts should be made to insure that leaks or heat
deteriorationhavenotresulted.   Replacethemasneces-

RUNNINGANGLE
Your 378 Vista™ includes a “closed water cooling” sys-
tem as standard equipment.  This system provides ad-
equate engine cooling without exposing the internal en-
gine to the detrimental effects of surface water, including
salt, highly polluted or silt-laden water. The engine own-
ers manual provides additional information regarding ser-
vice and maintenance of this equipment.
Hull planing surfaces have the least amount of drag at a
three to five degree  angle with the water.   This is the
preferredrunninganglewhenboating.   Therunningangle
has a  significant impact  on top  speed and handling.
Heavy load or certain water conditions may make it diffi-
cult to achieve the optimum running angle.  See Figure
E6.
The 378 Vista uses surface water as a cooling medium
for the heat exchanger. The cooling water employed en-
ters the system through a water intake and is relinquished
through the exhaust manifold system.
The running angle can be controlled through the use of
trim tabs. See Section E-7 - Trim Tabs and Section T-7
-
Trimming Your Boat for information on the use of trim
tabs.
