Mie (Inboard); Maintaining Transmission Fluid Level - Mercury MCM Series Important Information Manual

MIE (Inboard)

! CAUTION
If boat is in the water, seacock, if so equipped,
must remain closed until engine is to be
re-started, to prevent water from flowing back
into cooling system and/or boat. If boat is not
fitted with a seacock, water inlet hose must be left
disconnected and plugged (to prevent water
from flowing back into cooling system and/or
boat). As a precautionary measure, attach a tag
to the ignition switch or steering wheel of the
boat with the warning: Open seacock or recon-
nect water inlet hose before starting engine.
IMPORTANT: If a seacock is to be installed for
this purpose, valve used must have an internal
cross-sectional area equal to or greater than wa-
ter inlet hose to prevent restricting water flow
during normal operation. A 1-1/4 in. (32 mm), or
larger, brass ball valve or gate valve is recom-
mended.
1. If boat is in water, close seacock, if so equipped,
or disconnect and plug seawater inlet hose to
prevent seawater from entering boat.
2. Remove inlet hose from seawater pickup pump.
3. Using an adaptor, connect a garden hose from a
water tap to seawater pump inlet.
4. Partially open water tap (approximately 1/3 maxi-
mum). Do not use full water pressure.
5. Place the remote control lever in neutral position
and start engine.
! WARNING
When flushing, be certain the area around pro-
peller is clear, and no one is standing nearby. To
avoid possible injury, remove propeller.
! CAUTION
Do not run engine above 1500 RPM when flush-
ing. Suction created by seawater pickup pump
may collapse flushing hose, causing engine to
overheat.

! CAUTION
Watch temperature gauge on dash to ensure that
engine does not overheat.
6. Operate engine at idle speed in neutral for 10
minutes, or until discharge water is clear. Stop
engine.
7. Shut off water tap. Remove garden hose and
adaptor from pump inlet and reconnect water in-
let hose. Be sure to tighten hose clamp securely.
IMPORTANT: If boat is in the water, do not open
water inlet valve until engine is to be restarted to
prevent contaminated water from flowing back
into engine. If boat is not fitted with a valve, leave
water inlet hose disconnected and plugged.
Maintaining Transmission
Fluid Level
IMPORTANT: Be sure to push dipstick all the way
down into dipstick tube when checking fluid
level.
1. Remove dipstick to check transmission fluid lev-
el. Fluid level may be over the full mark because
fluid from the cooler and lines has drained back
into the transmission. If fluid level is low, add the
specified fluid through the dipstick hole until full
mark on dipstick is reached. DO NOT OVER-
FILL.
