MasterCraft X-5 User Manual

Inspect the Exhaust System for Leaks
This function should be performed prior to starting the engine; and then again 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 disconnected. Be certain that the throttle/shift control lever is in neu-
tral. 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 mov-
ing 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engine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loca-
tion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!
Before Each Use
(Prior to Starting the Engine)
Check That the Battery Is Fully Charged
As the boat is started, check all gauges, but pay particular attention to the voltmeter.
Whilestartingtheengine,checkthatthevoltmeterreadsbetween12.4and14.5volts.Anerratic
readingmaybeasignoflowvoltage.Thevoltmeteristhebestindicationofthestateofyourbat-
tery.However,itisnotfool-proof.Whilethereadingmayindicatethatthebatteryisproducingcur-
rent,ifduringapreviousoperationyouhadreasontosuspectaproblemwithyourbattery,check
with an authorized MasterCraft dealer’s service department.
 Currentmodelsareequippedwithalow-voltagebatteryalarm.Intheeventthatthestereohas
beenfunctioningwhentheboatengineisOFF,thevoltagedrainonthebatterymayresultindicul-
tiesre-startingtheboat.Toavoidthissituation,whenthevoltagelevelfallsto10.5volts,thesystem
willshutothestereosystemandsoundanalarmforaperiodoftwo(2)minutestoallowtheoperator
timetoturntheignitionkeyONandstarttheengine.Doingsowillallowtheengine’salternatorto
rechargethebattery.
 Chargedeadbatterieswithabatterychargerbeforeattemptingtostarttheengine.(Some
MasterCraftmodelsoeranoptionalbatterycharger;butneverjump-startthebattery.) Jump-
starting from another boat or battery is dangerous!Chargingadeadbatteryfromanenginewill
putunduestressonthealternator,whichmaycauseittofail.
When charging, batteries generate small amounts of dangerous hydrogen gas. This gas
is highly explosive. Keep all sparks, flames and smoking well away from the area. Fail-
ure to follow instructions when charging a battery may cause an electrical charge or
even an explosion of the battery, which could cause death or serious injury.
Crossing cables or jumper cables may result in damage to the electrical components due
to incorrect battery connections. Such damages may not be covered by your warranty.
