Using The Evinrude MFE Outboard
Engine De-Water
The MFE outboard is NOT a submersible en-
gine. However, due to the extreme operating
con
ditions this engine may experience, a
crankcase drain system has been provided to
de-water the engine should water intrusion
occur during deployment or accidental roll-
over.
This system allows the operator to quickly re-
move water and re-start the engine in an
emerg
ency situation. In most cases the en-
gine can be returned to normal operation with-
out damage.
Avoid submersion of the o
utboard. Damage
could occur to the engine wiring harness and
water could contaminate the oiling system.
Extended submersion, particularly in salt wa-
ter, could result in corrosi
on of internal com-
ponents such as piston rings, cylinder
sle
eves, and bearings.
After submersion, all boat and engine electri-
cal, fuel, and oiling systems must be
inspect-
ed for signs of water intrusion. A qualified
technician should
perform this service.
Once an outboard has been under water
(fresh or salt water), it M
UST be serviced
and started within three (3) hours of recov-
ery. Immedi
ate service can minimize the cor-
rosive effect that air has on the polished
surfaces of the
crankshaft, connecting rods,
and internal powerhead bearings.
IMPORTANT: If the outboard cannot be start-
ed or serviced immediately, it should be re-
submerged in fresh water to avoid exposure
to the atmosphere.
De-Water Procedure
CAUTION
NOTICE
1) Place shift lever in NEUTRAL and remove
the engine cut–off switch clip and tether
cord.
2) Twist throttle grip to slowest speed posi-
tion.
1. Slowest speed position
2) Turn the drain valves one–quarter turn
counter–clockwise to the DRAIN position.
Note: The handles on the drain valves will
point towards PORT.
Drain Position
To avoid outboard falling during de-
water procedure, tilt/run lever MUST
remain in the TILT position.
DO NOT run the outboard with
the drain
valves in the DRAIN position more than 3
minutes. Engine damage can result.
