SECTION I
MOUNTING THE IGNITION, COIL, STARTER RELAY
The MSD Watercraft Ignition may be mounted in any location except on the engine or near the
exhaust manifold. Excessive heat at these locations could damage the ignition.
It is recommended that a mounting plate be fabricated out of aluminum or stainless steel and
the ignition, coil and starter relay be mounted to it. Use the template supplied to assist you in
making a mounting plate for your craft. When selecting a mounting location make sure that the
ignition’s cable assembly will reach the battery and flywheel areas.
To simplify installation, MSD offers mounting plates for most applications (Figure 1). These
strong aluminum plates are pre-drilled and attach to the factory mounting locations. Part numbers
are listed on page 1.
Ignition
Using the Ignition as a template, mark the location of the mounting holes on the mounting
plate. Remove the ignition and drill a 1/4" hole at each marked location. Mount the ignition
using 10-32 x 3/4" or 5mm x 16mm stainless steel bolts (not supplied).
Ignition Coil
Using the coil as a template,
mark the location of the
mounting holes. Remove the coil
and drill a 1/4" hole at each
marked location. Mount the coil
using 1/4" x 3/4" or 6mm x 20mm
stainless steel bolts (not
supplied).
Starter Relay
When installing the MSD
Watercraft Ignition System it may
be necessary to remove the
stock starter relay and replace it
with an MSD External Relay, PN
4390. Using the relay as a
template mark the location of the
mounting holes. Remove the
relay and drill a 1/4" hole at each
marked location. Mount the coil
using 1/4" x 1/2" or 6mm x 12mm
stainless steel bolts (not
supplied).

SECTION II
INSTALLING THE SPARK PLUG WIRES
Each wire set includes two 90° dual crimp terminals,
two MSD Heli-Core Spark Plug Wires and a MiniStripper-Crimper. The MSD Mini-Stripper-Crimper is
supplied for assembling the MSD Spark Plug Wires.
Before using the tool it must be separated into two
parts. Separate it by bending the tool back and forth
until the center breaks (Figure 2).
1. Locate the correct cutting groove of the MiniStripper-Crimper for your wire. One groove is larger
to accept the 8.5mm Super Conductor Wire. Insert
the wire from the long side of the crimper tool and
push it through until it is flush with the other side
(Figure 3).
Remove the stock electrical box and mount the plate to existing
mounting bosses.
Figure 2 Separating the Mini-Stripper.
Figure 3 Stripping the Wire.
2. Press a single edge razor blade in the cutting groove
and push all the way down. Slowly rotate the wire
360° then remove the razor blade. Remove the wire
from the Crimper and slowly twist the cut end of
wire off in a counterclockwise direction.
3. Before crimping the terminals to the wires the

terminals must be modified as shown in Figure 4.
Bend the terminal ears over 90° by using a pair of
regular needle nose or long nose pliers.
4. Position the wire in the terminal until the insulation
sleeve is about 1/8" beyond its crimping tabs.
Position the conductor between the conductor
crimps and use a pair of needle nose pliers to crimp
the tabs tightly against the conductor (Figure 5).
Make sure the conductor does not slide out and do
not overtighten.

INSTALLATION INSTRUCTIONS
SECTION III FLYWHEEL AND TRIGGER PLATE
REMOVAL
Before installing the MSD Flywheel and Trigger Pickup
assembly, the stock magneto flywheel and stator plate must
be removed. Refer to your craft’s service manual for the
proper removal procedure.
TRIGGER PLATE ASSEMBLY
1. Assemble the trigger plate and pick-up assembly as
shown in Figure 8. Place the trigger plate assembly on
the bosses with the trigger on the side of the engine
where the wires normally exit the case (Figure 9). Screw
the supplied bolts and compression washers into the
case and lightly tighten to hold the trigger plate in the
center of the case's mounting pads.
5
Kawasaki 750 installation: The engine case mounting
pads of the Kawasaki 750 must be drilled and tapped
(Figure 10).
A. Drill and tap a hole on each pad 2.165" from
the center of the case. Drill and tap each hole
for a 6mm x 1mm allen head bolt using a No.
9 or 5mm drill bit and a 6mm x 1mm tap.
Each hole needs to be drilled 21mm deep.
B. Rotate the plate through the slotted positions
to ensure that the plate slides smoothly and
does not rock. If resistance is felt remove the
trigger plate and inspect the mounting
bosses for burrs and file flat if necessary.
Note: The PN 4312 Kawasaki 650/750 Trigger
Plate outside diameter is machined to fit the
mounting pads on the Kawasaki 750 engine.
When this plate is used on a Kawasaki 650
engine the trigger plate will have

6 INSTALLATION INSTRUCTIONS
CHECKING THE AIR GAP
It is important to have the correct air gap
between the pickup and the flywheel. Too much
may not trigger the ignition while too little may
cause contact to the pickup.
1. Position a small amount of clay on the top of
the trigger pickup (Figure 11).
2. Place the flywheel on the crankshaft and lightly
tap with a rubber or wooden object to hold it
in place.
3. Remove the flywheel and measure the
thickness of the clay. Refer to the chart (Figure
12) for the number of shims that will need to
be placed under the trigger pickup to obtain
the correct air gap between the trigger pickup
and the magnet in the flywheel. The correct
air gap is .050" to .094".
4. Insert the necessary shims under the trigger
pickup. Make sure the trigger retaining bolts
are the correct length for the number of shims
being used and are tightened firmly.
INSTALLING THE FLYWHEEL
Heating the flywheel in boiling water to evenly expand the
flywheel material before it is installed is necessary in the
following procedure. Be sure to wear adequate skin and
eye protection to prevent possible burning.
Note: On Kawasaki 750 engines the stock front engine
cover will require modification. The stock stator mounting
bosses will have to be machined out of the front cover so
that the MSD flywheel will fit. If you do not have access to
a machine shop, you can also use a stock Kawasaki 650
SX front cover. To modify the Kawasaki 750 flywheel
cover, machine the areas that are shaded in gray flush
with the flywheel cover (Figure 13).

SECTION V TIMING AND PROGRAMMING
The MSD Watercraft Ignitions innovative design allows you to static time the engine before the engine
is started. Study the special features shown in Figure 18 before proceeding.
Figure 19 How to Check Static Timing
At this point in the installation, the ignition, coil and
starter relay should be mounted and installed in the craft
along with the trigger plate assembly and flywheel. Now
you are ready to time the engine before starting the
engine.
1. Locate Top-Dead-Center (TDC) by placing a dial
indicator in the front cylinder and rotating the
crankshaft until the piston reaches the highest point
in the cylinder (Figure 19). When TDC is found, place
a mark on the engine case so that it lines up with the
TDC mark of the far left timing mark on the flywheel
as shown in figure (Figure 20).
2. Remove the ignitions backing plate. Position switch
1 to ON/ON/ON. Position selector S4 of switch 2 to
"ON" in order to disable the ignition's spark and
activate the built-in LED indicator. Turn the ignition
on/off switch to the ON position and place the spark
plugs with spark plug wires attached against ground.
WARNING: Do not trigger the ignition without the
spark plugs grounded and the plug wires
attached. Damage to the ignition coil may
result.
3. Slowly rotate the flywheel clockwise until the
small LED on the side of the ignition turns on.
When the LED is on, this indicates that the
magnet on the flywheel is entering over the
trigger pickup and that the ignition will fire at
this point. Note: As the flywheel is rotated the
timing marks will decrease from a high number
to a low number. Each dimple on the flywheel
represents 5° of timing adjustment with the first
dimple being TDC.
4. Follow the timing mark on the engine down to
the flywheel and determine where the timing
is set at by reading the timing mark on the
flywheel. Write this number down. (Because of the advanced circuitry in the MSD Ignition
the true timing is 5° less than what the timing mark will show). To achieve your true
timing, subtract 5° from the number you wrote down. Example - shown 30° less 5° equals
25° of true timing. Note: the MSD Digital Ignition can be programmed to electronically

Figure 19 Finding Top Dead Center.
Figure 20 Marking TDC.
10 INSTALLATION INSTRUCTIONS
retard the timing up to 7° less than what the
maximum true timing is set at. Always set the
trigger plate for the maximum amount of timing
the engine will ever run at.
5. To adjust the ignition's max timing the trigger plate
must be rotated counter-clockwise to advance the
timing or clockwise to retard the timing. To adjust
the plate without removing the flywheel, locate
the four trigger plate access holes in the flywheel
(Figure 21). Rotate the flywheel back to TDC and
then insert two 4mm allen wrenches into the holes
that line up with the trigger plate hold down bolts.
Loosen the bolts to allow the trigger plate to be
rotated.
6. Remove the two wrenches and rotate the flywheel
Figure 21 Loosening the Trigger Plate.
to the timing mark that was previously recorded.
Insert the two allen wrenches into the other two
holes (located 90° to the first two holes) so the
trigger plate rotates with the flywheel. Rotate the
flywheel clockwise or counter clockwise until the
desired timing mark on the flywheel lines up with
the timing mark on the engine (Figure 22).
7. Remove the two wrenches and rotate the flywheel
to TDC. Insert the allen wrenches into the first two
holes that line up with the trigger plate retaining
bolts and tighten the bolts.
8. Rotate the flywheel clockwise until the LED turns
on. Check to make sure the desired timing has
been set correctly. Install the flywheel cover.
Figure 22 Moving the Trigger Plate to
Adjust the Timing.
9. To program the engines final maximum timing
setting, position selectors S1-S3 of switch as required to match the desired timing. Example
- indicated timing is 25° less -3° (selectors S1-S3 set for 3°) = 22° maximum timing.
10. Turn the ignition switch to the OFF position and position selector S4 of switch 2 to off
position. Install the spark plugs and spark plug wires. The engine is now ready to start.
Note: If the application you are installing the system on permits, verify the ignition timing
using a timing light.
PROGRAMMING
The function of the timing curve is to match the ignition
to the burning rate of the fuel and the speed (RPM) of
the engine. By adjusting the timing of the ignition
maximum combustion pressure can be achieved at the
same time the piston is beginning the power stroke. Any
factor that changes the burning rate of the fuel or the
engine speed (RPM) can cause a need for an ignition
timing change.
To the right is a chart of some of the factors that will
affect ignition timing.

PROGRAMMING THE IGNITIONPROGRAMMING THE IGNITION
The MSD Ignition produces a computer-generated timing curve. Several programming options
are available to tune the basic timing curve to meet specific engine requirements. The factory
program settings are suitable for most watercraft, but changes can be made for special
applications. Three switches located under the aluminum plate of the MSD ignition module
select the programming options (Figure 24). IMPORTANT NOTE: If the selector switch
settings are changed, the ignition switch must be turned "off" and back "on" before the
new program functions become active. Always install aluminum backing plate to seal
switches.
The factory settings are:
Switch 1 Selectors S1-on, S2-on, S3-on (Max Timing = 0°)
Switch 2 Selectors S1-off, S2-on, S3-off (Begin Retard = 5000 rpm)
S4-off (Timing Setup = Ignition Operate)
S5-on, S6-off, S7-on, S8-off (Rev Limit = 7750 rpm)

14 INSTALLATION INSTRUCTIONS
SECTION VI
TROUBLESHOOTING
After installing the MSD Ignition System, if the craft fails to start, check the installation procedure
for any missed steps. If everything checks correctly, inspect the following:
1. Check the battery to make sure it is fully charged and properly connected. Also make sure
the terminal connections are clean and tight.
2. Make sure there are no loose wire connections. All connections should be free of rust, paint
or other debris.
3. Visually check the connections on the coil. Only two wires should be making contact to the
coil wires. Orange should be connected to the Orange wire on the coil and the blue wire
should be connected to the Black wire on the coil. Do Not connect any test equipment, test
lights, etc. to the coil wires.
4. Check the Ignition’s heavy Red wire for 12 volts. If 12 volts is not there, check the connections
or battery condition.
5. Check for 12 volts on the Violet wire of the MSD Ignition when the ignition on/off switch is in
the ON position.
6. Check the craft’s safety lanyard for proper operation.
7. Check the programming switch S4 of switch 2. Timing check - ignition operate position.
If there is still a problem present after checking all of the above steps, continue with the
following diagnostic procedures.
TESTING THE IGNITION FOR SPARK
After checking the wiring through the Troubleshooting Check List and the schematic on page 7
of the instructions, test the MSD Ignition to make sure that it is sparking. If the ignition produces
a spark in this test, then it can be assumed that the ignition is functioning properly. To check for
spark, follow this procedure:
1. Make sure the ignition switch is in the Off position.
2. Remove the spark plugs, then connect the spark plug wires to the plugs and position them
so you can observe the spark jump the plug gap. The plugs must be grounded.
3. Cut the two green trigger wires from the trigger pickup. When finished with this test you must
connect the wires together following the wiring tips discussed earlier in this manual.
4. Turn the ignition switch On. Do Not attempt to crank the engine.
5. Take a short length of wire and jump the two Green wires from the ignition together, then
release them quickly several times. When you do this, a spark should jump the spark plug
gap.
6. If there is no spark, substitute another ignition coil and repeat the test.
TESTING THE TRIGGER PICKUP
After checking the Ignition Module, you can test the operation of the trigger pickup.
Note: The two Green trigger pickup wires must be connected at this time.
1. The MSD Ignition’s Red wire should be disconnected from the battery or starter solenoid
while turning the engine by hand. Turn the ignition switch to the On position. NOTE: This can
be left connected if - the timing check switch is moved to the LED operate position. (The
switch must be in the LED position to check pickups or timing.)
2. While observing the LED on the side of the ignition, rotate the crankshaft by hand. When the
pickup and the magnet on the flywheel line up, the LED should illuminate.
3. If the LED lights, the trigger pickup is operating properly. If the LED does not light when
switch 2, S4 is on, check the air gap between the pickup and the flywheel magnet. It should
be .050" - .094". If the air gap is correct, the trigger pickup is at fault.
NOTE: Timing setup switch S4 must be in LED operate position.
