5.1 Fuel Tanks
Your  boat  is  equipped with  a  fuel tank.  In  the aft  state-
room under the bunk.
The tank is filled through a fuel fill. 
If your boat has a metal or aluminum tank installed, then 
the fuel tank should be inspected for signs of leaks, cor
-
rosion,  and/or  pitting  at  least  once  a  year.    Corrosion 
normally appears as a white,  chalky, or flaky substance 
on the surface  of the tank.  Sometimes, it also appears 
as pitting or small pockets of missing aluminum.  Another 
indication of corrosion is bubbles on the paint that coats 
the tank.  If any of these conditions are present, have an 
authorized  service  technician  inspect  the  tank  immedi
-
ately.  If a leak is found, turn off battery switches and dis-
connect shore  power  (See  Connecting  &  Disconnecting 
Shore  Power,  AC  Electrical  System),  which  explains 
the  proper  way  to  disconnect  and  disable  any  possible 
source  of  ignition).    Contact  your  dealer  or  Customer 
Service immediately.
5.1.1  Fuel Tank Capacity Monitoring
The fuel tank is equipped with a fuel level sending unit, which 
provides  an  electrical  signal  to  the  display  located  at the helm.

5.1.1  Fuel Tank Grounding System
The fuel tank and fuel fill on your boat are electrically 
grounded to the engine negative. (see the DC Electrical 
chapter).  This grounding system is designed to prevent 
the discharge of static electricity when fueling your boat.  
An authorized service technician should inspect this sys
-
tem at least once each year.
5.1.2  Fuel Gauge
The  fuel  gauge  as  shown  in  Fig.  5.1  is  located  at  the 
helm, and  is  the  indicator of  the  fuel  level in  your tank. 
Visually  inspect  the  reading  against  what  is  show
-
ing  in  the  tank  to  see  that  the  gauge  is  operational. 
 
Never enter the engine room without proper ventila-
tion first.  A spark caused by power tools or lighting 
equipment could result in fire or explosion which 
could cause personal injury or death.
