Inspect the Exhaust System for Leaks
This function should be performed after about three (3)-to-ve (5) minutes to determine whether
any leaks are apparent.
Step 1:FirstensurethattheengineisOFFandthattheenginesafetystartingswitchisdiscon-
nected. Be certain that the throttle/shift control lever is in neutral. The engine must
be cool.
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.
Step 2: Opentheenginecompartmentandvisuallychecktheexhaustsystemfromtheen-
ginetothetransomforanyobviousdamagetoexhaustlinesorthemuer.
Step 3: If leakageisapparent,tighten the hose clamps, being careful to avoidcrimping the
hose.Iftheleakageissignicant,orisoccurringatalocationotherthanthejoints(such
asasplitinahose),seeyourauthorizedMasterCraftdealer’sservicedepartmentfor
parts and service. This is important! Exhaust fumes can cause illness or impairment,
including carbon monoxide poisoning. Equally important to consider, leakage can
lead to a build-up of potentially explosive fumes within the engine compartment.
DO NOT IGNORE OR OVERLOOK THIS INSPECTION! REPAIR AS NECESSARY!
Inspect the Propeller
Shaft Log for Water
Entry
After approximately three (3)-to-ve (5)
minutes of boat operation in the water, shut o
the engine and open the engine compartment.
Be careful to avoid burns from contact 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
MasterCraft dealer’s service department for cor-
rection.
The engine box serves as a machin-
ery guard. The engine must be OFF
whenever the box is open. Cloth-
ing or body parts can get caught in
moving parts, causing death or seri-
ous injury. Keep away from moving
parts!
Attention must be paid to any leak-
age 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.
Inspect the Fuel System for Leaks
This function should be performed after about three (3)-to-ve (5) minutes of running the engine to determine whether any leaks are apparent.
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!
Afterthree(3)-to-ve(5)minutesofoperation,shutdowntheengineandensurethattheenginesafetystartingswitch
is disconnected. Be certain that the throttle/shift control lever is in neutral.Again,inspectthefuelsystemaswellas
possible.Inspectthefuelpumpgasket,fastenergaskets,regulatorsealandsendergasketforleaks.Iftheodorofgasoline
isstrongorifyouseevisualevidenceoffueloutsidethesystem,ceasealloperationsandtaketheboatimmediatelytoan
authorized MasterCraft dealer’s service department to determine the source of the leak. The leak must be repaired before
theengineisrestarted.BecausethelinesonlatemodelMasterCraftboatsarepressurized,theycanbedisconnectedand/or
removedONLYbyusingspecializedtoolsthatarenotavailabletothepublic.
 Reinspectafterthefueltankhasbeenlledfullforthersttimeoftheseason.
 Notethatfuelsystemsvarybymodel.Thepump-in-tanklocationontopofthefueltankwillresembleoneofthetwo

This is important! Fuel leakage can lead to a build-up of potentially explosive fumes within the engine compartment. DO
NOT IGNORE OR OVERLOOK THIS INSPECTION AND REPAIR AS NECESSARY!
