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.
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.
Install 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
Place a container below the oil filter.
Filter removal tip:To allow the oil to drain from the filter, loosen
the filter just enough to break the internal vacuum by turning oil
filter counterclockwise (to left). Let the oil drain back into the
system for 15 minutes prior to complete removal of the filter.
3
Remove the oil filter from the adaptor 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.
4
Remove oil filler cap (Port or Starboard). Add oil to bring level up
to, but not over FULL mark on dipstick.
IMPORTANT: Always use dipstick to determine exactly how
much oil is required.
