DC ELECTRICAL SYSTEM
Safety Information
This circuit is designed and manufactured in compliance with United States Coast Guard Standards (33 CFR
PART 183). No modifications may be made to it by the installer or user. It is the installer's responsibility to
assure that the installation of the control panel is done so in compliance with the above Coast Guard Stan-
dards. Failure to observe these requirements could be the cause of injury.
Distributor
The distributor is a solid state type without breaker
points; therefore, it requires no adjustment. It con-
sists of a cap, rotor, signal generator, igniter and
centrifugal advance system.
The signal generator consists of a signal rotor, a
magnet and a pickup coil. When the signal rotor
is driven, the amount of magnetic flux through the
pickup coil varies and an electric signal is con-
ducted at both ends of the pickup coil and sent to
the igniter.
The centrifugal advance controls the signal gen-
erator timing so as to control the ignition timing
according to the engine speed and load.

MARK
(988 RPM)
1. Attach a timing light to the #1 spark plug and mark the front crankshaft timing groove and the timing mark
on the scale embossed on the engine's front cover. .
2. Start the engine and warm it up to its normal operating temperature.
3. Using the timing light, align the timing groove in the front crankshaft pulley with the proper timing mark
on the ignition timing scale embossed on the engine's front cover. Do this by loosening and slowly rotat-
ing the distributor body.
Timing Specifications: 10° ± 2° BTDC at idle (900 rpm)
