This procedure must be performed while
the outboard motor is in the water. A
flushing attachment or test tank can be
used.
A diagnostic tachometer should be used for
this procedure. Results may vary depending
on whether testing is conducted with the
flushing attachment, in a test tank, or with the
outboard motor in the water.

tions, see page 42.
