MasterCra boats are equipped with a highly innovative fuel
system. is system is designed to provide years of trouble-free
service. Some of the latest innovations related to fuel handling
safety are also incorporated into the fuel delivery system.
e system uses a fuel pump mounted in a capsule that is in-
stalled directly in the fuel tank. A similar system has been used
in automotive vehicles for many years and has demonstrated
reliable service. e pump system in your boat was specically
designed for the marine environment and contains a number of
added safety components that are unique to the marine environ-
ment. Because of the special nature of the design, there are no
user-serviceable parts. Any parts in need of service or mainte-
nance will need to be addressed by an authorized MasterCra
dealer. e technical team there is equipped with the special
tools necessary to disassemble and service the fuel capsule and
associated parts.
The fuel line in the boat’s bilge area that goes from the tank
to the engine is a special multi-layer armored line that is cov-
ered with a special material known as a fire sleeve. The fire
sleeve affords protection to the fuel line in the unlikely event
of a boat fire.
e sleeve is colored orange for easy identication of the fuel
line. MasterCra recommends daily inspection of the bilge for
foreign materials and the possibility of gas or oil leakage detec-
tion. As part of your daily inspection, include a visual check of
the orange re-sleeved fuel line. If you see damage to the sleeve
or line or in any way suspect damage or fuel leakage, DO NOT
START THE BOAT! Immediately call an authorized Master-
Cra servicing dealer and let him or her assess the situation.
Even if the outing is canceled, leaking fuel can cause serious
damage to the environment and may be a potentially hazard-
ous situation for people and property in the area. erefore, it is
critical to attend to this matter as soon as possible.
Gasoline is extremely ammable and high explosive under certain
conditions. Always stop the engine and never smoke or allow
open ames or sparks within fty (50) feet of the fueling area
when fueling.
Take care not to spill gasoline. If gasoline is spilled accidentally,
wipe up all traces of it with dry rags immediately and dispose of
properly on shore.
Gasoline is explosive. If a gasoline odor is present or gasoline
is visually observed in the bilge area during inspection, DO NOT
START YOUR ENGINE! Remove the ignition key from the ignition
switch and call an authorized MasterCraft dealer for service.
Allowing the fuel level in the fuel tank to fall below one-quarter of
a tank full may affect the reliability of the fuel pump or result in
damage to the fuel pump, which is not covered under warranty.
Indmar Engines
e following information applies to boats equipped with Ind-
mar engines (which includes the RPT-1, MCX, LY6 and 8.1L):
What Type of Gasoline To
Use
All standard Indmar EFI engines run on
unleaded fuel of 89 octane or higher. Ind-
mar recommends purchasing fuel from a
supplier that advertises availability of fuel
that meets “TOP TIER” specications.
is fuel has additives and detergents
that will reduce the build-up of deposits
in the engine.
e goal of the TOP TIER detergent
gasoline standards is to create a win-
ning situation for gasoline retailers,
engine manufacturers and boat opera-
tors. Currently, many gasoline retailers
provide fuels with lower-quality additive
packages that can build up deposits on
