If engine should overheat, turn off engine, look
for obstructions to water pick-up. If any obstruc-
tions are found, clear the obstructions and run
engine again at 1500 RPM in neutral and check
temperature gauge to verify condition. If over-
heating still occurs, return to port at low RPM
to prevent excessive overheating and engine
damage. Consult with your certified engine
dealer for service.
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).
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 re-
pairs; maintain a close visual watch on the prob-
lem hose and also on the bilge water level.

RUNNINGANGLE & POWER TRIM/TILT
Hull planing surfaces have the least amount of drag at a
three to five degree angle with the water. This is the pre-
ferred running angle when boating. The running angle
hasasignificantimpactontopspeedandhandling. Heavy
load or certain water conditions may make it difficult to
achieve the optimum running angle. See Figure E7.
B. Fresh Water Cooling - Inboard Option
The Vista™ inboard include a “closedwatercooling”sys-
tem as optional 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-
ersmanualprovidesadditionalinformationregardingser-
vice and maintenance of this equipment.
The running angle can be controlled through the use of
power trim (stern drives) and/or trim tabs. See Section
E-8 -TrimTabs and Section T-7 - TrimmingYour Boat for
information on the use of trim tabs and tilt/trim control
switches (if applicable).
The Vista™ inboard uses surfacewaterasacoolingme-

enters the system through a water intake and is relin-
quished through the exhaust manifold system.

are kept free of mud, weeds and other debris. Some
boating areas require that additional strainers or water
intake filters be installed. Reference Section P-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.
