MasterCraft X-5 User Manual

Engines should always be operated within
engine manufacturer guidelines. Failure
to do so may cause significant damage to
the engine and drive train and is not cov-
ered under warranty!
Elevation and weather also have a very no-
ticeableeectonthewide-open-throttlepowerof
an engine. Since oxygen gets thinner as elevation
increases, the engine begins to starve for air. Hu-
midity, barometric pressure and temperature have
anoticeableeectonthedensityofairsinceheat
and humidity thin the air.
This phenomenon can become particularly
apparent when an engine is propped for use on a
cool, dry day in spring and then is operated on a
hot, humid day in summer, and does not have the
same performance. Although some performance
can be regained by dropping to a lower-pitch pro-
peller, the basic condition still exists. The propeller
is too large in diameter for the reduced power out-
put. An experienced marine dealer can determine
how much diameter to remove from a lower-pitch
propellerforspecichigh-elevationlocations.
MasterCraft’s engine manufacturers sug-
gest that consumers consult with the dealer from
whom the boat was purchased regarding the best
propeller for the application in which the boat will
primarily be run. However, be aware that chang-
ing the propeller may void the warranty. Again,
working with an authorized MasterCraft dealer is
your best bet to ensure excellent performance.
Unusual Operating Conditions
If the body of water is unknown, talk to local boaters about the type of obstacles that
may be encountered beneath the water’s surface. Rocks, tree stumps and sandbars are
all dangerous and damaging. Be especially wary of rivers and man-made lakes. Rapidly
changing conditions can cause daily changes in underwater hazards.

When traveling through weedy areas, keep an eye on the engine temperature gauge.
Weedscaughtupandblockingthewaterowthroughtherawwaterintakeortransmis-
sion cooler will cause trouble. Also, after leaving the weedy area, shift to neutral for a few
seconds and then to reverse for a few seconds to unwind any weeds that may have wrapped
around the propeller.
Docking and Tie-Up
Approach the dock slowly, with the starboard side of the boat if possible. The natural
tendency to torque steer with the rotation of the propeller at slow speeds makes docking eas-
ier on that side. Also, use wind and current to your advantage when docking.
Before tying up the boat, be sure to use enough dock bumpers to protect the boat from
damage. If possible, tie-up with the bow toward the waves. Use good quality double-braid-
ed nylon line. Tie-up only to the cleats or tie-down eyes. Never use the handrails or ski pylon.

If the boat is to be kept in or near water for the season, consider the purchase of a boat
lift and bottom paint for the hull. These lifts prevent the build-up of marine growth on the
hull as well as protecting the boat from damage typical of on-water storage, such as blister-
ing. Make sure the boat lift supports the hull correctly. See the next section, Lifting the Boat.
NOTE: On boats that are equipped with the engine synchronizing switch (models
with two engines), this switch should be disengaged during docking or when loading
and unloading the boat from a trailer. These maneuvers require a sensitive touch and
control that may not be realized when the switch is engaged.
