TAKING CARE OF UNEXPECTED PROBLEMS
SUBMERGED OUTBOARD
MOTOR
A submerged outboard motor must be
serviced immediately after it is
recovered from the water in order to
minimize corrosion.
If there is a TOHATSU dealership
nearby, take the outboard motor to the
dealer immediately. If you are far
from a dealer, proceed as follows:
1. Remove the engine cover, and rinse
the outboard motor with fresh
water to remove salt water, sand,
mud, etc.
2. Drain the vapor separator as
described on p. 102.
3. Change the engine oil as described
on p. 83 – 84. If there was water in
the engine crankcase, or if the used
engine oil showed signs of water
contamination, then a second
engine oil change should be
performed after running the engine
for half an hour.
4. Remove the alternator cover
(p. 57).
5. Remove the spark plugs (p. 85),
and remove the emergency stop
switch clip from the emergency
stop switch. Pull the emergency
starter rope, rotate the flywheel a
few revolutions to completely
expel any water from the engine’s
cylinders.
If the engine was running when it
submerged, there may be
mechanical damage, such as bent
connecting rods. If the engine binds
when cranked, do not attempt to
run the engine until it has been
repaired.
When cranking the engine with an
open ignition circuit (spark plugs
removed from the ignition circuit),
remove the clip from the emergency
stop switch to prevent possible
damage to the ignition system.
