- General Information
1. Open the manual vent screw on top of the fuel cap.
2.
Turn the fuel cap until it contacts the tab lock.
3. Press down on the tab lock. Rotate the fuel cap 1/4 turn to relieve the
pressure.
4. Press down on the tab lock again and remove the cap.
DIRECTIONS FOR USING THE PRESSURIZED PORTABLE FUEL TANK
1. When installing the fuel tank cap, turn the cap to the right until you hear a
click. This signals that the fuel cap is fully seated. A built‑in device
prevents overtightening.
2. Open the manual vent screw on top of the cap for operation and cap
removal. Close the manual vent screw for transportation.
3. For fuel hoses that have quick disconnects, disconnect the fuel line from
the engine or fuel tank when not in use.
4.
Follow Filling Fuel Tank instructions for fueling.
Filling Fuel Tank
!
WARNING
Avoid serious injury or death from a gasoline fire or explosion. Use caution
when
filling fuel tanks. Always stop the engine and do not smoke or allow
open flames or sparks in the area while filling fuel tanks.
Fill the fuel tanks outdoors away from heat, sparks, and open flames.
Remove the portable fuel tanks from the boat to fill them.
Always stop the engine before filling the tanks.
Do not completely fill the fuel tanks. Leave approximately 10% of the tank
volume unfilled. Fuel will expand in volume as its temperature rises and can
leak under pressure if the tank is completely filled.
PORTABLE FUEL TANK PLACEMENT IN THE BOAT
Place the fuel tank in the boat so the vent is higher than the fuel level under
normal boat operating conditions.
Engine Oil Recommendations
Mercury or Quicksilver NMMA FC‑W certified SAE 10W‑30 4‑Stroke Marine
Engine Oil is recommended for general, all‑temperature use. If NMMA certified
synthetic blend oil is preferred, use Mercury or Quicksilver SAE 25W‑40
Synthetic Blend Marine 4‑Stroke Engine Oil. If the recommended Mercury or
Quicksilver NMMA FC‑W certified outboard oils are not available, a major
FC‑W certified 4‑stroke outboard oil may be used.
