2017 OWNERS MANUAL /

Often, batteries that have been stored over winter will require
recharging. Only an authorized battery charger should be used to
charge the battery(ies) in MasterCraft boats. Use only a three-stage
or more battery charger. It is important that the operator never
turn a battery charger immediately to “start,” as the sudden jolt of
voltage may cause damage to the electrical system, particularly the
control modules for the ballast system. Regardless of the time of
year, care should always be used when charging a battery(ies).
Step 3
Follow all instructions for reactivating the engine and drive train as
detailed in the Ilmor Marine Engine Owner’s Manual.
NOTE: Due to the complex nature of the engine and drive train re-
activation process, MasterCraft recommends having an authorized
MasterCraft or Ilmor dealer perform this function.
Step 4
Ensure that all drain plugs throughout the boat and drive train have
been reinstalled to avoid unwanted water intrusion.
Step 5
If applicable, reconnect and verify that all hoses to the heater, the
head, the fresh water wash down, and the wet bar are in proper
and was drained for storage, fill the system with fresh coolant solu-
tion per instructions in the Ilmor Engine Owner’s Manual.
Step 13
For all models, with the boat in the water, cycle the key ON and then
OFF two (2) or three (3) times, allowing ten (10) seconds between
key cycles, before cranking the engine. This allows the fuel pump to
prime the fuel lines. Start the engine. In the event the engine does
not respond, allow a two-minute cool-down period for every thirty
(30) seconds of cranking. When the engine fires, keep a close watch
over the gauge readings and check for leakage and abnormal nois-
es. Keep speeds low for the first fifteen (15) minutes to allow the
engine to reach normal operating temperatures.
PROPELLER MAINTENANCE
Propeller damage is caused by striking solid objects. If the propeller
is not rotating at the time it strikes a solid object, the damage is
usually confined to just one blade and may be difficult to see. If the
propeller is rotating when it strikes an object, usually the resulting
damage can easily be seen on all blades.
working condition with no leaks.
Step 6
Check the engine compartment and bilge for signs of nesting
animals. Clean as necessary.
Step 7
Check the entire engine system for fluid, oil and coolant levels. Add
as necessary.
Step 8
Check the entire engine for cracks or leaks caused by freeze damage.
Step 9
Check all hose clamps for tightness. Install the bilge drain plug and
the rear drain plug (if applicable).
Step 10
Grease the propeller spline and install the propeller.
Step 11
Perform daily maintenance as noted previously in this Owner’s Man-
ual. If it was not done prior to storage, perform annual maintenance
as well.
Step 12
If the boat is equipped with the optional fresh water cooling system
CHECKING/REPAIRING
PROPELLERS
Step 1
Ensure the engine is OFF and the emergency safety stop switch is
disconnected.
Step 2
Clamp a small rule scale to the shaft strut, parallel to the shaft so
that the end of the scale is 3/32-inches from the leading edge of a
propeller blade.
Step 3
Rotate the propeller slowly. There should be no more than 3/32-
inch variance between the blades. If the propeller is damaged, see
an authorized MasterCraft dealer for repair or replacement as
necessary.
