SPARK PLUG
Remove the spark plugs as follows:
1. Remove the bolt securing the ignition coil.
2. Pull out the ignition coil.
3. Loosen and remove the spark plug using the
box wrench in the tool bag.
Your outboard motor comes equipped with the
following “standard” spark plug for normal
usage.
Standard spark plug NGK LKR6E
NOTICE
Non-resistor types of spark plugs will
interfere with the function of the elec-
tronic ignition, causing misfiring, or
causing problems with other electronic
boat equipment and accessories.
Use ONLY resistor type spark plugs in
your outboard motor.
Your authorized Suzuki Marine Dealer can
determine if the standard spark plug is suitable
for your type of motor usage by inspecting the
color of the plug’s porcelain center electrode
insulator after operation.
If the plug tends to run hot (usually evidenced
by whitening of the insulator or a burnt elec-
trode), stop using your motor immediately as
severe engine damage may result. If the plug
tends to run cold (usually evidenced by black-
ening of the insulator or a wet electrode), per-
formance may suffer. Ask your authorized
Suzuki Marine dealer to evaluate either of these
problems to determine the cause.
