Fuel and Oil Recommendations
ZAJ6110101007
Gasoline
Suzuki highly recommends that you use alcohol-free
unleaded gasoline with a minimum pump octane rating
of 87 (R+M/2 method) or 91 (Research method).
However, blends of unleaded gasoline and alcohol with
equivalent octane content may be used.
Allowable maximum blend of a single additive (not
combination)
5% Methanol, 10% Ethanol, 15% MTBE
CAUTION
If leaded gasoline is used, engine damage
may result. Use only unleaded gasoline.
Engine oil
Oil quality is a major contributor to your engine’s
performance and life. Always select good quality engine
oil.
Suzuki recommends the use of a SAE 10 W – 40 NMMA
certified oil.
If NMMA certified FC-W oil is not available, select a good
quality 4-cycle motor oil from the following chart
according to the average temperatures in your area.
Gear oil
Suzuki recommends the use of SUZUKI Outboard Motor
Gear Oil. If it is not available, use SAE 90 hypoid gear oil
which is rated GL-5 under the API classification system.
Break-In Procedures
ZAJ6110101008
The first 10 hours are critically important to ensure
correct running of either a brand new motor or a motor
that has been reconditioned or rebuilt. How the motor is
operated during this time will have direct bearing on its
life span and long-term durability.
Break-in period
10 hours
Warm-up recommendation
Allow sufficient idling time (more than 5 minutes) for the
engine to warm up after cold engine starting.
Throttle recommendation
NOTE
Avoid maintaining a constant engine speed
for an extended period at any time during the
engine break-in period by varying the throttle
position occasionally.
First 2 hours
For the first 15 minutes, operate the engine in-gear at
idling speed. During the remaining 1 hour and 45
minutes, operate the engine in-gear at less than 1/2
(half) throttle (3 000 r/min).
NOTE
The throttle may be briefly opened beyond
the recommended setting to plane the boat,
but must be reduced to the recommended
setting immediately after planning.
Next 1 hour
Operate the engine in-gear at less than 3/4 (three -
quarter) throttle (4 000 r/min).
Last 7 hours
Operate the engine in-gear at a desired engine speed.
However, do not operate continuously at full throttle for
more than 5 minutes.
