Pre-Engine Operation
2-Stroke Engines
Premix Fuel: Yamaha recommends the use of
Yamalube. If it is not available, use a TCW 3 rated
oil. Recommended fuel is 86 octane minimum.
Premix fuel and oil is to be used on all outboard
motors except 4-stroke and HPDI models.
All C-Series engines should have a mixture of
25:1 for the first 10 hours of operation. Oil inject-
ed engines are recommended to have a 50:1 mix-
ture for the first 10 hours of operation. Use cau-
tion when premixing fuel in the fuel tank. Put 20
percent of the total fuel volume in before adding
oil. This ensures proper mixing.
NOTE: Ring Free is recommended for all
Yamaha engines on a continuous basis.
Priming Fuel System
Before turning on the key switch, prime the fuel
system either by the primer bulb or electric primer
pump. This ensures against any fuel leaks. Repair
them immediately if found. It is especially impor-
tant for EFI and HPDI engines to help avoid dam-
age to the VST pump.
NOTE: Leaking fuel fittings could result in
severe injury or fire.
Precision Blend
On 90hp engines and below, before filling the oil
tank, perform the following steps:
1. Turn the key switch to the ON position and
ensure the alarm is operable.
2. While the key is in the ON position, start fill-
ing the engine oil tank.
NOTE: Watch for when the oil alarm deactivates.
Most units now have the self bleeding line on the
oil pump, If not, continue with step 4 on the next
column.
For all 2-stroke 115hp engines and above, per-
form the following steps:
1. Turn the key to the ON position and test the
oil warning system on the multifunction
tachometer (see illustration following).
2. Fill the remote oil tank. Watch for the alarms
to deactivate.
