Off-Season Storage - TOHATSU MFS 25B Owner's Manual

3. Off-season storage

Before you put your outboard motor
in storage, it is a good opportunity to
have it serviced and prepared by your
dealer.
CAUTION
!
Before servicing the motor for storage:
● Remove the battery cables.
● Remove the spark plug caps from the
spark plugs.
● Do not run the motor out of the water.
■ Engine
① Wash the engine exterior and
flush the cooling water system
thoroughly with fresh water. Drain
the water completely.
Wipe off any surface water with an
oily rag.
② Use a dry cloth to completely
wipe off water and salt from the
electrical components.
③ Drain all fuel from the fuel hoses,
fuel pump, and vapor separator,
and clean these parts.
Keep in mind that if gasoline is
kept in the vapor separator for a
long time, gum and varnish will
develop, causing the float valve to
stick, restricting the fuel flow.
④ Remove the spark plugs and
spray storage oil (available from
an authorized dealer) into the
combustion chamber through
the spark plug holes while slowly
turning the motor over using the
recoil starter.
⑤ Change the engine oil.
INSPECTION AND MAINTENANCE
⑥ Change the gear oil in the gear
case.
⑦ Apply grease to the propeller shaft.
⑧ Apply grease to all sliding parts,
joints, nuts, and bolts.
⑨ Stand the outboard motor up
vertically in a dry place.
WARNING
!
Be sure to use cloth to remove fuel
remaining in the cowl and dispose of it
in accordance with local fire prevention
and environment protection regulations.
■ Battery
① Disconnect the battery cables.
② Wipe off any chemical deposits,
dirt, or grease.
③ A p p l y g re a s e t o t h e b a t t e r y
terminals.
④ Charge the battery completely
before storing it for the winter.
⑤ Recharge the battery once a month
to prevent it from discharging and
the electrolyte from deteriorating.
⑥ Store the battery in a dry place.

shaft of the electric starter motor with
grease.
