Filling Fuel Tank; Engine Oil Recommendations - Mercury 25 Jet 4-Stroke Manual

Filling Fuel Tank

Avoid serious injury or death from a gasoline fire or explosion.
Always stop the engine and do not smoke or allow open flames
or sparks in the area while filling fuel tanks.
Fill fuel tanks outdoors away from heat, sparks, and open flames.
Remove portable fuel tanks from boat to refill them.
Always stop engine before refilling 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

We recommend the use of Mercury or Quicksilver NMMA FC‑W
certified 10W‑30
all‑temperature use. If NMMA certified synthetic blend 25W‑40
4‑Stroke outboard oil is preferred, use Mercury or Quicksilver
synthetic blend 4‑Stroke Outboard 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.
