FUEL SYSTEM INSPECTION
Gasoline and its vapors are highly
flammable and explosive.
Failure to check for and repair fuel
leakage may result in fire or explo-
sion.
Check the fuel system for leaks,
cracks, or malfunctions. If any problem
is found, do the necessary repair or
replacement as required. If repair is
necessary, consult your nearest
Yamaha Sport Boat dealer.
Always properly dispose of gasoline
soaked rags. They can sponta-
neously ignite.
Checking points:
1. Carburetor leakage.
2. Fuel pump malfunction or leakage.
3. Fuel tank leakage.
4. Fuel hose joint leakage.
5. Fuel hose cracks or other damage.
6. Fuel filter leakage.
7. Fuel valve leakage.
8. Air vent check valve leakage.
9. Fuel filler clamps and hoses.
The United States Coast Guard
requires that all inboard boats like your
Sport Boat have visual access to fuel
filler clamps and hoses. The Sport Boat
has two access panels for this pur-
pose.
One access panel is located on the
upper deck wall on the port side, visible
when the rear seat back is removed.
The lid for the fuel tank compartment is
the other access panel. Remove the
center portion of each seat cushion
and then the bench seat. Remove the
screws holding the lid to inspect the
fuel tank area.
