Fuel Gauge
Your fuel gauge is read from a sensor in
the tank. If the boat is up and running, an
accurate reading is not always possible.
Be sure to check the level at rest and
inspect the sender for proper electricval
conections and leaks at the fuel tank. The
fuel gauges on your 43MY are located at
the helm station. The photo below shows
the fuel gauge at the Helm Panel.

Fuel Quality
Refer to your Engine Manual, included
with your owner’s packet, for specific fuel
requirements for your engine, i.e., recom-
mended octane level.
Fuel Additives
Many times, fuel tank leaks are the result
of galvanic corrosion of the tanks, pitting
from the inside out. For galvanic corrosion
to begin or continue, the corrosion site
must be in contact with a liquid that con-
ducts electricity. Generally, water is re-
quired to sustain galvanic corrosion.
However, alcohol additives in gasoline,
particularly methanol and ethanol, in
presence of very small quantities of water,
transform the gasoline into a blended
solution of gasoline and water. This solu-
tion sometimes becomes a conductive
liquid that can promote galvanic corrosion.
In the last ten to twelve years due to
changes in gasoline formulations, fuel has
become potentially more corrosive. New
formulations can contain up to ten percent
alcohol, primarily ethanol, and oxidizers
such as MTBE and others. These formula-
tions vary widely from brand to brand,
regon to region, and season to season.
Consumer products sold as fuel additives,
such as “dry-gas”, are primarily methanol.
With either methanol or ethanol in fuel,
water contamination may result in creating
a conductive liquid.
Refer to your Engine Manual for recom-
mendations concerning fuel additives.
Refer to the Winterization and Storage
Pages in the Cleaning and Maintenance
Section of this Owner’s Manual concern-
ing the use of fuel stabilizers.
Always follow the manufacturer’s recom-
mendation when using fuel additives or
stabilizers.
