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 thoroughly 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 shutting 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 discon-
nect the engine safety starting switch. Open the engine compart-
ment. The engine 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 between 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 engine will be running. DO NOT
USE OIL ADDITIVES AT ANY TIME.
