Spark Plug Test; Flooded Engine - ProBoat ZELOS 48G Owner's Manual

Spark Plug Test

CAUTION: Before testing the spark plug, clean up
spilled fuel and close fuel containers. Failure to do
can result in injury, fire or damage.
Remove the spark plug from the engine and attach the
plug wire and boot to the spark plug. Place the threaded
end of the spark plug against the muffler. Pull the starter
cord in a quick continuous motion to turn over the engine
and ensure there is a spark.
If there is no spark:
• Adjust the spark plug gap to 0.6–0.7mm (0.24–0.27 in)
• Install a new spark plug (LOSR5017)
CAUTION: Do not test the spark plug near the
spark plug hole or residual fuel may ignite.

Flooded Engine

Fuel
The engine will not start if too much fuel is in the
cylinder. Excess fuel can be expelled by following these
steps. We recommend using safety goggles.
1. Disconnect and remove the spark plug.
2. Pull the starter cord in a continuous motion.
3. Replace the spark plug and make sure the boot is
tightly secured.
NOTICE: Always clean up spilled fuel. Failure to do so
may result in injury or damage.
Water
The engine will not start if it has been flooded with
water. Excess water can be expelled using these steps:
1. Turn off all the electronics and disconnect the boat
battery.
2. Disconnect and remove the spark plug.
3. Hold the boat upside down and pull the starter cord
in a continuous motion until you no longer see water
coming out of the boat.
4. Replace the spark plug, then thread it in half of the
way.
5. Place your finger over the carburetor opening and
repeatedly crank the engine using the pull starter.
Fill the cylinder with enough fuel to displace the
water inside of the engine.
6. Disconnect and remove the spark plug, them repeat
Step 3.
Owner's Manual
7. Carefully spray motor fluid (DYN5500) into the
cylinder head through the spark plug hole while
slowly pulling the starter cord. The spray will displace
any remaining water and fuel from inside the engine.
8. Spray motor fluid onto the spark plug's center
electrode to remove any excess fuel. Allow it to
completely dry.
9. Replace the spark plug and make sure the boot is
tightly secured.
NOTICE: If the engine does not start, follow the
Spark Plug Test instructions to ensure the spark
plug is working properly.
Tip: Replace the fuel inside the fuel tank if it is
contaminated during submersion.
