Engine Oil

Checking

Discharge of oil, coolant, or other engine/drive fluids into the environment is restricted by law. Use caution not to spill oil,
coolant, or other fluids into the environment when using or servicing your boat. Be aware of the local restrictions governing
the disposal or recycling of waste, and contain and dispose of fluids as required.
1. With the engine warm but not running, wait five minutes to allow the oil to drain into the oil pan.
2. Remove the dipstick, wipe it clean, and install it fully into the dipstick tube. Wait 60 seconds to allow trapped air to vent.
3. Remove the dipstick and observe the oil level. The oil level must be between FULL or OK range and ADD. Install dipstick
into dipstick tube. If the oil level is low, refer to Filling.
Oil Level—Overfilled
IMPORTANT: Do not overfill the engine with oil. An overfilled crankcase can cause a fluctuation or drop in oil pressure, rocker
arm clatter, and a loss of engine performance.
An overfilled crankcase (oil level too high) can cause a fluctuation or drop in oil pressure, and rocker arm clatter. This condition
results in the engine crankshaft splashing and agitating the oil, causing it to foam (become aerated). The aerated oil causes the
hydraulic valve lifters to bleed down. This results in rocker arm clatter and loss of engine performance.
Care must be taken when checking the engine oil level. The oil level must be maintained within the full maximum and the add
minimum mark on the dipstick. To avoid getting a false reading, adhere to the following procedures.

Filling

IMPORTANT: Do not overfill the engine with oil.
IMPORTANT: Always use the dipstick to determine the exact quantity of oil or fluid required.
