OTHER OBSERVATION POSSIBLE CAUSE REMEDY
• RAVE valve does not open • Check, refer to section ENGINE and
COOLING SYSTEM
• Faulty water regulator valve • Check, refer to COOLING SYSTEM
• DI models: The DI system is in limp
home mode. “MAINT” is displayed

• Refer to section ENGINE and COOLING
SYSTEM and check the fault codes in
the MPEM
• Low fuel pressure
(DI models) • Check fuel pump pressure output
• Jet pump related problem • Check propulsion components. Refer

• Exhaust system blockage • Check and repair
OTHER OBSERVATION POSSIBLE CAUSE REMEDY
Engine RPM too high
• Faulty rev limiter in MPEM
(carburetor models)
• Check, refer to section ELECTRICAL
SYSTEM
• Improper impeller pitch (too low) • Check/replace, refer to section PROPUL-
SION SYSTEM
Jet pump cavitation
• Damaged leading or trailing edge of
impeller
• Check/replace
NOTE: Leading edge damage contributes
to poor performance from start. Trailing
edge damage contributes to poor top per-
formance and stator vanes erosion.
• Sealing of ride plate, jet pump support
or jet pump
• Check/reseal, refer to section PRO-
PULSION SYSTEM or HULL/BODY
OTHER OBSERVATION POSSIBLE CAUSE REMEDY
Monitoring beeper sounds
