PRE-OPERATION CHECKS
When you check the oil level with the dipstick, you might notice the engine oil
appears milky or the oil level has increased. If you notice either condition,
change the engine oil. See the following table for an explanation of these
conditions.
Operating Method
Result
Effect
Running the engine below
3,000 rpm for more than 30%
of the time so the engine does
not warm up.
• Water condenses in the
engine and mixes with the oil,
resulting in a milky
appearance.
• Unburned fuel mixes with the
oil, increasing the volume of
oil.
The engine oil deteriorates,
becomes less efficient as a
lubricant, and causes an
engine malfunction.
Frequent starting and stopping
without allowing the engine to
warm up.
Fuel
Check the fuel level and refill if
necessary. Do not fill the fuel tank
above the UPPER LIMIT.
Refer to the boat manufacturer’s
instructions.
Use unleaded gasoline with a
Research Octane Number of 91 or
higher (a Pump Octane Number of 86
or higher). Use of leaded gasoline
may cause damage to the engine.
Never use gasoline that is stale,
contaminated, or mixed with oil.
Avoid getting dirt, dust or water in
the fuel tank.
