Problem Cause and Solution
The engine is loosing
RPM. The boat is not over-
loaded and the hull bottom
and running gear are clean
and in good condition.
• The engine may be having a problem with a sticky
anti-siphon valve, located in the fuel line near the
fuel tank, that is restricting the fuel flow. Remove &
clean or replace the anti-siphon valve.
• The remote gasoline fuel filter could be dirty. In -
spect and replace the fuel filter.
• The primary fuel filter on the engine may be dirty.
Inspect and replace the fuel filter.
• The electronic engine control system on the engine
is malfunctioning. Repair the engine control system.

tioning. Repair the fuel injection system.
Accessory Problems
The livewell pump runs, but
does not pump water.
• The strainer on the intake scoop is clogged prevent-
ing the water from getting to the pump. Put the boat
in reverse to clean the strainer.
• There is an air lock in the system. Run the boat
above 15 m.p.h. and the pick-up scoop will force the
air lock past the pump and prime the system.
• The thru-hull valve is not open. Open valve.
• The valve in the livewell is not open. Open the valve
in the livewell.
The automatic float switch
on the bilge pump raises
but does not activate the

pump impeller housing.
