Fuel Recommendations; Fuel Pump Filter Inspection And Replacement - Honda Marine BF25A Owner's Manual

SERVICING YOUR OUTBOARD MOTOR
FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump
octane rating of 86 or higher.
These outboard motors are certified
to operate on unleaded gasoline.
Unleaded gasoline produces fewer
engine and spark plug deposits and
extends exhaust system life.
Never use stale or contaminated
gasoline or an oiVgasoline mixture.
Avoid getting dirt or water in the fuel
tank.
Occasionally you may hear a light
"spark knock" or "pinging"
(metallic rapping noise) while
operating under heavy loads. This is
no cause for concern.
If spark knock or pinging occurs at a
steady engine speed, under normal
load, change brands of gasoline. If
spark knock or pinging persists, see
an authorized Honda marine dealer.
68
Running the engine with persistent
spark knock or pinging can cause
engine damage.
Running the engine with persistent
spark knock or pinging is misuse,
and the Distributor's Limited
Warranty does not cover parts
damaged by misuse.
Fuel Pump Filter Inspection
and Replacement
The fuel pump filter is located under
the engine cover between the fuel
coupling and the fuel pump.
Water or sediment accumulated in
the filter can cause loss of power or
hard starting.
To
prevent engine
malfunction, inspect the filter and
replace when necessary.
Gasoline is highly
flammable and explosive.
You can be burned or
seriously injured when
handling fuel.
Stop the engine and keep
heat, sparks, and flame
away.
Handle fuel only
outdoors.
Wipe up spills
immediately.
