Changing Fluids

See MAINTENANCE CHART for lubricant change frequency. Lubri-
cant should be changed before placing boat in storage.
Power Trim or Power Steering fluids do not require changing.
Coolant in closed cooling system should be changed at specified in-
tervals by your Authorized MerCruiser Dealer.
CHANGING CRANKCASE OIL AND FILTER
IMPORTANT: Change oil when engine is warm from operation.
Warm oil flows more freely, carrying away more impurities. Use
only recommended motor oil (see SPECIFICATIONS).
1
With engine at normal operating temperature, remove dipstick. In-
stall Quicksilver Crankcase Oil Pump onto dipstick tube.
Insert hose end of crankcase oil pump into an appropriate container
and using pump handle, pump until crankcase is empty. Remove
crankcase oil pump.
2
Turn oil filter counterclockwise (to left); remove and discard old oil
filter and old sealing ring.
Coat sealing ring on new filter with motor oil. Install new sealing ring
and filter by turning clockwise (to right). Tighten filter securely. Do not
overtighten.
3
Remove oil filler cap. Add correct type oil (see SPECIFICATIONS)
to bring level up to, but not over FULL mark on dipstick.
IMPORTANT: Always use dipstick to determine exactly how
much oil is required.
