Inspect After Operating; Submerged Outboard Motor - TOHATSU BFT 80A Owner's Manual

Inspect After Operating

1. Stop the engine and remove the
engine cover (see page 62).
2. Confirm the cooling water leakage
from the engine.

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 outboard
motor dealer nearby, take the
outboard motor immediately to the
dealer. 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.
If the outboard motor 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 outboard motor until it has
been repaired.
2. Drain the vapor separator as
described on page 157.
3. Change the engine oil (see page
135).
4. Remove the spark plugs (see pages
137–140). Operate the starter to
expel water from the engine's
cylinder.
5. Pour a teaspoon of engine oil into
each spark plug hole, then pull the
emergency starter rope several
times to lubricate the inside of the
cylinders.
Reinstall the spark plugs.
6. Install the engine cover and lock
the fixing lever securely (see page
62).
MAINTENANCE
7. Attempt to start the engine.
• If the engine fails to start, remove
the spark plugs, clean and dry the
electrodes, then reinstall the spark
plugs and attempt to start the
engine again.
• If there was water in the engine
crankcase, or the used engine oil
showed signs of water
contamination, then a second
engine oil change should be
performed after running the engine
for 1/2 hour.
• If the engine starts, and no
mechanical damage is evident,
continue to run the engine for 1/2
hour or longer (be sure the water
level is at least 100 mm (4 in)
above the anticavitation plate).
8. As soon as possible, take the
outboard motor to your outboard
motor dealer for inspection and
service.
