Refer to Maintenance for change interval. Crankcase oil should be changed before placing boat in storage.
Power Trim or Power Steering fluids do not require changing.
Changing Crankcase Oil and Filter
IMPORTANT: Change crankcase oil when engine is warm from operation. Warm oil flows more freely,
carrying away more impurities. Use only recommended engine oil (refer to Specifications).
1
With engine at normal operating temperature, remove drain plug from oil drain hose or remove dipstick.
NOTE: If engine is factory equipped with Quick Drain Oil Hose, pull tether through bilge drain before removing
drain plug from oil drain hose.
2
Drain crankcase oil using quick drain oil hose.
NOTE: If drain plug is not accessible because of boat construction, oil may be removed through dipstick tube,
using a Quicksilver Crankcase Oil Pump. (See Quicksilver Accessory Guide.)
3
Drain crankcase oil using Quicksilver Crankcase Oil Pump.
A
Insert hose end of crankcase oil pump onto an appropriate container and using handle, pump until crankcase
is empty.

Remove pump.
4
After oil has drained completely, reinstall drain plug or dipstick and tighten securely.
5
Remove and discard oil filter and its sealing ring.
6
Coat sealing ring on new filter with engine oil and install. Tighten filter securely (following filter manufacturer's
instructions). DO NOT overtighten.
7
Remove oil filler cap. Add recommended engine oil to bring level up to, but not over, FULL or OK RANGE
mark on dipstick. Refer to Specifications.
8
Start engine and check for leaks.
IMPORTANT: Always use dipstick to determine exactly how much oil is required.
ENVIRONMENTAL HAZARD! Discharge of oil or oil waste into the environment is restricted by law. Do
