(5) Stop filling when the fuel just becomes
visible in the bottom of the filler tube. Do
not “top off” the tank, because gasoline
could spill out.

(7) Close the fuel tank filler cap by pushing it
until it locks in place. Make sure that the
fuel tank filler cap is securely closed.
Engine Med RX Fuel Additive
As the fuel mixture burns in your engine’s
combustion chambers, carbon deposits are
left behind. Over time, these deposits can re-
duce performance and even cause engine
damage. Marine engines tend to run at lower
operating temperatures than other engines,
making them more likely to accumulate these
harmful deposits.
Engine Med RX, available from your Yamaha
Boat Dealer, is formulated to remove existing
deposits and, when used continuously, pre-
vent new ones from forming, while also help-
ing to keep fuel injectors and other fuel
system components clean for proper perfor-
mance and longer engine life.
