IGNITION TIMING
Before checking ignition timing with a stroboscop-
ic timing light (dynamic test), it is mandatory to
scribe a timing mark on the PTO flywheel (static
test) corresponding to the specific engine.
Also, the timing mark scribed on the PTO flywheel
can be used to troubleshoot a broken magneto
woodruff key.
CAUTION:
The relation between the PTO fly-
wheel mark position and crankshaft position may
change as the PTO flywheel might tighten/loos-
en on the crankshaft. As an example, when the
engine is accelerated out of water, PTO fly-
wheel may tighten then loosen when the en-
gine is decelerated. This will result in a false
ignition timing reading. Always verify PTO fly-
wheel mark position before checking ignition
timing with an appropriate timing light. If mark
does not align with tool, repeat static test to en-
sure flywheel has not loosen before changing
the ignition timing.
NOTE:
Do not use the factory mark found on the
PTO flywheel to check ignition timing or trouble-
shoot any problems.
947 Engine
Normally ignition timing adjustment should not be
required. It has been set at factory and it should
remain correctly adjusted since every part is fixed
and not adjustable. The only time the ignition tim-
ing might have to be changed would be when re-
placing the crankshaft, the magneto rotor, the trig-
ger coil and the MPEM. If the ignition timing is
found incorrect, you should first check for proper
crankshaft alignment. This might be the indication
of a twisted crankshaft.
With this DC-CDI system, the ignition timing can
be checked with either the engine hot or cold. Al-
so, the ignition timing is to be checked at 3500
RPM with the timing light.
NOTE:
Between 3000 and 4000 RPM, the spark
advance does not change. So when checking igni-
tion timing at 3500 RPM, a change in engine
speed within
±
500 RPM will not affect the timing
mark when checked with the timing light.
Static Test
All Engines
1. Disconnect MAG side spark plug wire and con-
nect wire to grounding device then remove
spark plug.
CAUTION:
Never crank engine with spark plugs
removed unless spark plug cables are connect-
ed to the grounding device.
2. Remove PTO flywheel guard.

3. Install timing mark pointer tool on engine using
wing nuts previously removed.
TYPICAL
1. Timing mark pointer tool (P/N 295 000 130)

4. Remove middle screw securing the engine to
the rear engine mount. Reinstall screw with
timing mark pointer tool.
