manual provides additional information regarding
service and maintenance of this equipment. See your
Four Winns dealer for availability.
The running angle can be controlled through the use
of power trim (stern drives) and/or trim tabs. See
Section E-8 - Trim Tabs and Section S-7 - Trimming
Your Boat for information on the use of trim tabs and
tilt/trim control switches.
These Vista models use surface water as a cooling
®
medium for the heat exchanger. The cooling water
employed enters the system through a water intake
and is relinquished through the exhaust manifold
system. Some boating areas require that additional
water intake filters be installed. Reference Section P-3
-
Equipment Installation, in this manual for installation
instructions and consult your Four Winns dealer
regarding any special equipment that may be re-
quired.
Should an engine intake or an exhaust or
cooling 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.
E - 6 RUNNING ANGLE & 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
preferred running angle when boating. The running
angle has a significant impact on top speed and
handling. Heavy load or certain water conditions may
make it difficult to achieve the optimum running angle.
See Figure E4.
Figure E4: Running Angle
A. Power Trim
Trim angle is how far in or out, the lower unit is
positioned in relation to the bottom of the boat.
The trim angle of the lower unit has a distinct affect
on the running angle of the boat.
The power trim system permits control of the trim
angle of the drive unit relative to the boat, at the touch
of a button.
It allows the drive unit to be raised (trimmed out) for
shallow water operation. Power trim also allows the
operator to adjust the drive unit while underway to
provide the ideal running angle for a given load and
water condition. Additional information can be found
in the engine owner’s manual.
