WARNING
EWJ00510
Before operating your watercraft, become

Engine break-in
The engine break-in period is essential to al-
low the various components of the engine to
wear and polish themselves to the correct op-
erating clearances. This ensures proper per-
formance and promotes longer component
life.
CAUTION:
ECJ00421
● For the first 2 tankfuls of fuel, premix the
fuel in a fuel-to-oil ratio of 25:1.
● After break-in, premix the fuel in a fuel-
to-oil ratio of 50:1 for normal operation.
(1) Launch the watercraft, start the engine,
and then board the watercraft. (See page
40 for engine starting procedures.)
(2) Run the engine at the lowest possible
speed for 5 minutes.
(3) Gradually apply throttle to 3/4 or less.
(4) Operate the watercraft at 3/4 throttle or
less for the first tankful of fuel.
(5) Fill the fuel tank once more with fuel in a
fuel-to-oil ratio of 25:1, and then proceed
with normal operation.
CAUTION:
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
