the voltage level reaches a set level of 11.5 volts, the system will shut off the stereo system and sound the alarm for a period of two
minutes to give boaters ample time to adjust.
If you have a dead battery, charge it with a battery charger before attempting to start the engine. Jump-starting from another
boat or battery is dangerous. Charging a dead battery with the alternator on your 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. Failure to follow instructions when charging a battery
can cause an electrical charge or even an explosion of the battery which could cause serious injury or death.
Crossing cables or jumper cables can result in damage to the electrical components due to incorrect battery connections.
Such damages are not covered by your warranty.
CHECK THE ENGINE OIL LEVEL
Because you will get an accurate reading
only after the engine has run long enough to thor-
oughly warm up (to at least 140 degrees F), this
should be one of the last checks you conduct before
boating. Run the engine in the water. If you are
checking the transmission fluid at the same time,
run the engine at least five minutes in the water (to
warm the transmission fluid), and check the fluid
immediately after shutting down to get an accurate
reading for that. As long as you will be checking
the oil fairly quickly (within two minutes of shut-
ting off), there is no need to re-start and run the
engine again.
Step 1: After operating the engine at idle while in the
water for at least three minutes or until warm, turn the
engine OFF and disconnect the engine safety start-
ing switch. Open the engine compartment. The en-
gine oil dipstick is located on one side of the engine.
Step 2: Allow two minutes before checking. Then
remove the dipstick and wipe it off. Insert it fully and
immediately remove. Check that the oil lever is be-
tween the ADD and the SAFE marks on the dipstick.
Step 3: Add oil, if necessary, through the valve cover
and only enough to bring to the SAFE mark on the
dipstick. Overfill may result in damage to the engine
that is not covered by warranty. Use SAE 15W40, API
SJ/CH4 oil. 20W40 oil may be substituted but only if it
meets the API SJ/CH4 standards. Below 20 degrees
Fahrenheit, use SAE 10W30 SJ/CD type oil if the en-
gine will be running. DO NOT USE OIL ADDI-
TIVES AT ANY TIME.
