Note: Do not use compressed air, open flame nor heat dryers. Excess heat will shrink the cotton filter media.
Compressed air will blow holes in the element.
Step 7: After cleaning the air filter, always re-oil before using. Spray K&N air filter oil down into each pleat with one pass per pleat.
Wait 10 minutes and re-oil any white spots still showing. Or use the oil from a squeeze bottle, down into the bottom and along each
pleat with just one pass in each pleat. Let the oil wick into the cotton for 20 minutes. Re-oil any white spots still showing.
Note: Never use the K&N air filter without oil. The filter will not stop the dirt without the oil. Red dye is added to
K&N air filter oil to assist in determining whether you have complete coverage after application. Never use auto-
matic transmission fluid, motor oil diesel fuel, WD-40, LPS or other lightweight oils for this purpose.
Step 8: Re-install. Make sure the element seats properly before tightening the clamp screw.
MasterCraft recommends that your annual–
or 100 hour–maintenance requirements be
performed by your MasterCraft dealer. The
staff there has the proper equipment and tech-
nical training to best meet your service needs.
REPLACE THE
RAW WATER PUMP IMPELLER
Change the raw water pump impeller an-
nually. This is extremely important! Through
normal wear and tear, the impeller usually
lasts no more than one season even under
ideal conditions. If it does not function prop-
erly–and it will not when worn–it can cause
serious engine overheating and potentially
void your warranty!
MasterCraft recommends that this procedure
be performed by a MasterCraft service technician.
If, however, you wish to complete this function
yourself, detailed instructions are included under
Before Each Use, Check the Impeller section of
this manual, where documentation was provided
to assist boat owners who experience overheat-
ing problems or who boat in “dirty” water.
HAVE AN ENGINE
TUNE-UP PERFORMED
A complete engine tune-up, including replace-
ment of the PVC valve, spark plugs, distributor
cap, rotor and ignition wires (if needed) should be
performed annually. Also, some engines require
adjustments for spark, dwell and idle. All of these
functions require special knowledge, tools and test
equipment.
For this reason, MasterCraft strongly recom-
mends having the engine tune-up performed by
your dealer.
