Check the Transmission Cooler for Debris
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. The transmission cooler is located either near the top
or on the side of the engine.
Step 2: Loosen the clamp surrounding the water intake hose at the back of the
transmission cooler and slide off the hose.
Step 3: Check the screen inside for signs of debris. Even small amounts of debris
must be removed to prevent the material from clogging the cooler and pos-
sibly causing it to malfunction. The screen is permanently in place and your
boatmustnotbeoperatedwithanyforeignmaterialsblockingtheflowof
water through the cooler.
Step 4: After cleaning, re-attach the hose and clamp.
Important: This is a critical function of routine maintenance.
Even clean-appearing waterways may have debris such as pine
needles or moss that can enter the cooling system and create a
blockage against this screen. Failure to perform this function can
result in serious overheating of the engine. Damage to the engine
caused by overheating is not covered by warranty! Always pay attention to your temperature
gauge, even if you are carefully performing this check. Blockage of the transmission cooler or a
faulty raw water impeller are too-frequent causes of overheating. Water in the transmission may
void the warranty!
Check the Coolant Level
This procedure applies only to boats equipped with the fresh water
cooling system or closed system. 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 dis-
connected. Be sure the throttle/shift control lever is in neutral. Open
the engine compartment and locate the closed cooling system tank
adjacent to the engine.
Step 2: Remove the cap and check the level, which should be 2/3 full. If the
level is below that, add coolant (only ethylene glycol or pro-
pylene glycol) in the appropriate mixture with distilled water. DO
NOToverllthetank.DO NOT mix anti-freeze types. See the Stor-
age and Winterization section of this manual for additional details
regarding coolants.
Step 3: If the tank was completely empty, see your MasterCraft dealer for
assistance immediately as your engine cooling system needs purg-
ing. This function should be completed only by a trained
MasterCraft service technician.
