Warning System
1
The outboard warning system incorporates a warning horn inside
the boat. The warning horn may be located inside the remote
control (a) or under the dash (b) connected to the ignition key
switch.
The system is designed for the warning horn to emit either a continu-
ous beep or intermittent short beeps. This will alert the operator and
help identify the following listed problems.
• The warning horn sounds continuously
The problem is engine overheat. See explanation following.
• The warning horn sounds intermittent short beeps.
The problem is low oil level in the oil injection system. See expla-
nation following.
2 When the ignition key is initially turned on, the warning horn will
sound for a moment as a test to tell you the system is working.
Failure of this test indicates a problem. Have the outboard
checked by your dealer.
