STARTING THE ENGINE
Fuel Priming
Hold the priming bulb so that the
outlet end is higher than the inlet (so
that the arrow on the priming bulb
points up), and squeeze it until it feels
firm, indicating that fuel has reached
the outboard motor. Check for leaks.
Be careful not to spill any fuel.
Spilled fuel vapor may ignite. If
any fuel is spilled, make sure the
area is dry before starting the
engine.
Do not touch the priming bulb with
the engine running or when tilting
up the outboard motor. The vapor
separator could overflow.
