Failure to maintain your coolant at the proper level can cause engine damage. Your warranty will not cover engine
damage due to overheating or any other cause associated with improper coolant levels.
Check the Alternator Belt
for Looseness or Damage
Because this process should be completed while the engine is cool and
cannot cause burns to your skin, we recommend you do this before starting your
boat.
Step 1: Ensure the engine is OFF and the engine safety starting switch discon-
nected. Be certain that the throttle/shift control lever is in neutral. Open
the engine compartment and locate the alternator belt.
Step 2: Check the alternator belt tension at the top, also midway between the
circulating pump pulley and at the alternator pulley. The belt should be
tightenoughsothatitwilldeflectnomorethanone-quartertoone-half
inchwhenpressedwiththethumbornger.
Note: If the belt is too tight, excessive belt and bearing wear
can occur. If the belt is too loose, slippage can occur, resulting in
low alternator output and rapid belt wear.
Step 3: If your engine is not equipped with a belt tensioner, loosen the alternator
mounting hardware and tighten the hardware. Re-check the belt tension.
On engines with serpentine belt systems, however, no change is neces-
sary. Belt tension is maintained by the automatic belt tensioner.
Step 4: Check the underside of the belt that actually runs in contact with the pul-
leys. Look for signs of excessive wear, cuts or weakness across or in the
grooves. If there are any, replace the belt. We recommend contacting
your MasterCraft dealer for service assistance.
Inspect the Battery Connections
and Hold-Downs
Because poor connections or hold-downs can result in erroneous voltme-
ter readings, we recommend you do this before starting your boat.
Step 1: Ensure the engine is OFF and the engine safety starting switch discon-
nected. Be certain that the throttle/shift control lever is in neutral. Locate
the battery. Batteries are placed in a variety of locations, depending on
the model. Check under the observer seat or behind the rear seat.
Step 2: Check that the battery post connections are clean and tight. If not:

touch the positive terminal with the wrench.
• Loosen and remove the positive terminal connection.
• Remove the battery hold-downs and remove the battery from the boat.
• Clean corrosion from the battery posts with a battery terminal cleaner.
• Clean the battery with a water-and-baking-soda solution. Use care to avoid allow-
ing the solution to enter the battery vents. Rinse the battery with fresh water.
