6-10 Indmar Marine Engines
The ignition systems in these engines are high energy,
electronic ignition systems that require special equipment
in order to adjust the timing accurately. Since there are
no parts in the system that will wear and alter the timing,
these engines are essentially "timed for life". The only
way the timing will be altered is by loosening the hold
down clamp and turning the distributor. If, for some rea-
son, you loosen the distributor hold down clamp and turn
the distributor, Indmar suggests that you do not operate
your engine until your dealer has reset the timing to origi-
nal specifications. Altered ignition timing can cause
severe engine damage, which is not covered under the
terms of your warranty.
FUEL SYSTEM
The fuel system consists of fuel lines, fuel pump, and an
unused fuel recovery system. Fuel in the system is under
pressure and must be relieved before servicing. Because
of the inherent danger of fuel leakage into the bilge, do
not attempt servicing or maintaining components of the
fuel system.
Your Indmar dealer has factory trained technicians and
U.S. Coast Guard approved marine grade parts required
for fuel systems.
CARBURETOR ADJUSTMENTS
The carburetor on your engine has been carefully adjust-
ed at the factory and has had sealing caps applied to the
idle mixture screws to prevent further adjustment.
Altering the original factory settings will change the emis-
sions characteristics of your engine and may put your
engine "out of compliance" with the emission standards
in California. If you are experiencing drivability problems
that may be related to the operation of your carburetor,
Indmar suggests that you contact your dealer for assis-
tance. Unauthorized removal of the carburetor sealing
caps may void the warranty on your engine if damage
occurs as a result.
If you have a carbureted engine and live and will always
operate your boat in an area with an altitude greater than
2500 feet above sea level, it may be necessary to have
your carburetor re-jetted to operate properly. It may also
be necessary to reduce your propeller size to allow the
engine to operate at the appropriate RPM. Your boat
dealer is best equipped to help you make these adjust-
ments.
