2017 OWNERS MANUAL / 274
Because the vertical surf racks are mounted with a clamping
system, two people will be required for installation and removal,
as this will lower the risk of damaging the tower (dents, scratches,
scus, etc.). Defects as a result of removing or installing surf racks
are not covered by warranty.
The ZFT7 tower has dedicated port and starboard surf rack
installation kits. Be sure that the correct kit is being used before
attempting to install it on the boat.
To install vertical surf racks:
1. Installer 1 hold the board racks with the crossbar in place along
the upper portion of the ZFT7 tower. A second installer, installer
2, will be positioned inside the boat should be ready to attach the
inner clamp and bolt the rack to the tower.
2. Installer 1 will hold the cross bar against the front billet leg
(with the rubber padding contacting the tower leg, see photo).
The cross bar needs to he held high enough that there is an
approximately 1/8” between the billet leg and the pocket (milled
into the front of the cross bar, see photo to right).
3. Installer 2 will line up the bolt holes and attach the clamp
hardware from the inside of the boat, loosely tightening the
bolts with Loctite 242 applied to the first 1/4” of the threads
in a crisscross pattern. A torque wrench must be used when
tightening the bolts to ensure that each bolt is adequately
tightened.
4. Torque each bolt to 80- ft-lbs. As the bolts are tightened with
a torque wrench, the adjacent bolts will likely loosen due to the
additional clamp load. Run through the crisscross tightening
pattern several times until all bolts are torqued to 80 ft-lbs.
Removal is a reversal of installation.
The vertical surf racks on the ZFT7 tower are not designed for
removal. If removal is necessary MasterCraft recommends taking
the boat to an authorized dealer for removal. Defects as a result
of removing, or attempting to remove or install surf racks are not
MILLED IN POCKET

pad rest against the front tower leg)

Surf Tow Points
Surf tow points are mounted on the inboard side of the ZFT7 and
ZFT4 towers near where the tower legs bend into the top of the tower
so that ropes do not interfere with board racks or boards.
Surf tows are intended for surfing only. MasterCraft highly discour-
ages towing any other sport from these mounts. Do not tow from all
3 to
wer tow points at once.
Since surf tow points are not vertical, a slack rope is more likely to
fall o. Double loop (if possible) rope around the tow point to reduce
the risk of a rope falling o the tow point.
Troubleshooting
Lights: If the lights do not work when the switch is turned ON, check
the main circuit breaker panel to determine whether the circuit has
tripped, and reset if necessary. If the circuit continues to trip or if
the circuit is on but the lights still do not work, take the boat to an
authorized MasterCraft dealer for attention.
Speakers: If the audio speakers on the tower do not work, verify
electrical cir
cuits by checking the main circuit breaker panel. Reset
if it has tripped. If it still does not work, take the boat to an autho-
rized MasterCraft dealer for repair.
Boar
d Racks: If boards will not sit securely in place, and it is de-
termined that the proper board for the proper rack is in use, do not
leave the board in the rack. Take the boat to an authorized Master-
Craft dealer to determine the underlying cause.
