(III) OUT-OF-SEASON STORAGE
The off-season gives you a good opportunity to have
your TOHATSU serviced or overhauled by your
dealer. Not only will the motor be better preserved in
storage, but it will also be ready for immediate use as
soon as the new season opens.
Storaging procedures are as follows:-
1) Wash outboard motor externally and flush cooling
system completely with fresh water.
Dry and wipe over with an oily rag.
2) Drain fuel from tank, pipe lines, fuel pump and
carburetor and clean them with air blast. To
prevent internal rusting of the separate fuel tank
while out of service, add a little 2 cycle engine oil
and turn the tank over so that it covers all
surfacer. or completely fill the tank with fuel
which has a greater than normal ratio of oil.

der head, piston. exhaust port and manifold. Add
2 cycle engine oil through the spark plug hole and
inject oil into crank case and cylinder from the
carburetor and turn the engine a few times by turn-
ing the recoil starter.
