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
automatic 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 technical training to best meet your service needs.
REPLACE THE
RAW WATER PUMP IMPELLER
Change the raw water pump impeller annually. 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 properly–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
overheating 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
recommends having the engine tune-up
performed by your dealer.
