“SERVICE REQUIRED” OR “CHECK ENGINE”
INDICATOR (EFI ENGINES ONLY)
Some boats are equipped with a digital dash which dis-
plays the words “SERVICE REQUIRED” and/or
“CHECK ENGINE,” and some boats are equipped with
a Check Engine light. This alerts you when the ECM
(Engine Control Module) detects a possible engine prob-
lem. If the indicator goes on, return to dealer for service.
