INSPECT THE THROTTLE AND
SHIFT CABLES FOR KINKS, WEAR
AND INTERFERENCE
Some engine parts become very hot during operation.
This inspection must be completed while the engine is cool to
prevent burns to your skin. Perform this task before starting
the boat.
1. Ensure the engine is OFF, the engine safety starting switch is
disconnected and the throttle/shift control lever is in neutral.
2. Open the engine compartment and locate the throttle and shift
cables. Follow each cable back under the floorboards and feel for
any kinks and wear on the outer jacket. Any sign of cable damage is
cause for replacement. See your authorized MasterCraft dealer’s
service department if you notice any cable damage.
MasterCraft dealer’s service department. Otherwise, the engine
may not perform properly.
Add-on equipment may adversely affect the alternator output or
overload the electrical system. Such damage may not be covered
by the warranty.
If a replacement battery is required, be certain to select a marine
battery with at least eight-hundred (800) cold-cranking-amps at
zero degrees (0o) Fahrenheit. Before disconnecting the battery,
make sure the ignition key and all accessories are in the OFF
position. Also remember to re-attach the cables in the proper
order, with the positive cable connected to the positive [+] post
and the negative cable connected to the negative [-] post.
When charging, batteries generate small amounts of dangerous
hydrogen gas. This gas is highly explosive. Keep all sparks, flames and
smoking well away from the area. Failure to follow instructions when
charging a battery may cause an electrical charge or even an explosion
of the battery, which could result in death or serious injury.
MasterCraft recommends the use of an AMP spiral-cell battery,
such as the Optima brand. These batteries exceed other batteries
in holding and extending a charge.
