2017 OWNERS MANUAL /

If the boat is to be moored for a long period of time, use chafing
protectors to protect the gel coat finish. Leave a little slack in the
lines, allowing for some wave movement or tidal action where
applicable. 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 blistering. Make sure the boat lift supports the hull
correctly. See the next section, Lifting the Boat information in the
Care and Maintenance section of the Owner’s Manual.
Humidity, barometric pressure and temperature have a noticeable
effect 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 propeller, the basic condition still exists.
The propeller is too large in diameter for the reduced power output.
An experienced marine dealer can determine how much diameter
to remove from a lower-pitch propeller for specific high-elevation
locations.
MasterCraft’s engine manufacturer suggests that consumers con-
sult 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 changing 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.
Stay well clear of floating debris. What looks to be a small branch in
the water may well turn out to be an entire tree.
When traveling through weedy areas, keep an eye on the engine
temperature gauge. Weeds caught up and blocking the water flow
through the raw water intake or transmission 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 pos-
sible. The natural tendency of traditional inboards is to torque steer
with the rotation of the propeller at slow speeds to make docking
easier on the starboard side. On MasterCraft models equipped with
the DockStar rudder system the boat will dock well to either the port
or starboard side.
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-braided nylon line. Tie-up only to
the cleats or tie- down eyes. Never use the handrails or ski pylon.
Boats left at docks or at anchor must be monitored on a regular
basis to avoid sinking. Maintain adequate battery charge to
operate the bilge pumps to avoid excess water intrusion. If leaking
is detected, immediately remove the boat from the water and
determine the cause.
