Points to note on Sailboats (for T9.9)
When mounting the outboard motor on the
motor bracket of a sailboat, check the fol-
lowing points:
8 When using the outboard, the cavitation
plate should be 50 mm (2 in) or more
below the water surface to prevent pro-
peller damage. Because a sailboat can
001558
pitch considerably, mount the motor low
enough so that the propeller will not con-
tact the water surface during motor-pow-
ered operation.
8 When sailing, the outboard motor should
be able to be tilted up out of the water so
the propeller does not contact the water
spray. Disconnect the fuel line connection.
8 Check that the outboard motor does not
interfere with the rudder.
8 Check that the engine can be easily start-
ed and stopped.
8 Check the ease of operating the gear shift
and throttle control.
8 If mounting the outboard motor on a well-
type boat, exhaust gases and blow-by
gas flow must be allowed to exit the boat.
A special kit designed for this purpose
can be ordered through your Yamaha
dealer.
NOTE:
Refer to the section "TRIMMING OUT-
BOARD MOTOR" for instructions on setting
the trim angle of the outboard.
