Fuel Systems Section 3
Fuel Level Sounding
Your centerline fuel tank might be equipped with a
system that allows you to manually sound the tank to
determine fuel on-board. You can use this system as
a back-up in case of electrical malfunctions or as a
method to confirm the electric fuel gauge reading.
You can access the fuel tank and sounding cap
through the deck access plate just forward of the lean-
ing post. Refer to the Fuel System Diagram in this
section for exact location. The boat must be at rest
and level before you remove the sounding cap.
Review Fueling Procedures in this section and
understand all of the safety-related information before
proceeding with this fuel sounding operation.
Remove the cap and integral sounding rod. The
sounding rod has incremental markings to help you
determine your fuel on-board.
Follow these guidelines when reinstalling the sounding
cap:
• DO NOT over-tighten the sounding cap.
• DO NOT use tools to reinstall the cap.
• Confirm that no liquid gasoline is around the
sounding cap after five minutes of boat operation.
!
WARNING
Do not attempt to remove the sounding cap if
the boat is in motion. Spilled liquid gasoline is
a fire and explosion hazard. Gasoline vapor is
extremely flammable and highly explosive
under certain conditions.
