If a replacement battery is required, be certain to select
a marine battery with at least seven-hundred-fifty (750)
cold-cranking-amps at zero degreees (0
o
) Fahrenheit.
Before disconnecting the battery, make sure the ignition
key and all accessories are in the OFF position. Also re-
member to re-attach the cables in the proper order, with
the negative cable connected to the negative [-] post and
the positive cable connected to the positive [+] post.
When charging, batteries generate small amounts
of dangerous hydrogen gas. This gas is highly ex-
plosive. 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 a spiral cell type bat-
tery, such as the Optima brand. These batteries exceed
other batteries in holding and extending a charge.
Inspect the Throttle and Shift Cables
for Kinks, Wear and Interference (RTP-
1 and Twin MCX Installations Only)
Some engine parts become very hot during opera-
tion. This inspection must be completed while the
engine is cool to prevent burns to your skin. Per-
form this task before starting the boat.
Step 1:
Ensure the engine is OFF and the engine
safety starting switch disconnected.
Be certain that the
throttle/shift control lever is in neutral.
Step 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 re-
placement. See your authorized MasterCraft dealer’s
service department.
Inspect the Propeller Shaft Log for
Water Entry
After approximately three (3) to five (5) minutes of boat
operation in the water, shut off the engine and open the
engine compartment. Be careful to avoid burns from con-
tact with hot engine parts. The boat is equipped with a
dripless shaft log and if it is showing any signs of drip-
ping, the boat must be taken to an authorized Master-
Craft dealer’s service department for correction.
The engine box serves as a machinery guard. The
engine must be OFF whenever the box is open.
Clothing or body parts can get caught in moving
parts, causing death or serious injury. Keep away
from moving parts!
Attention must be paid to any leakage occurring in
the propeller shaft log area. Water intrusion into
the transmission, which can happen if excessive
leakage is occurring may cause serious damage.
Such damage may not be covered by the warranty.
