Rev Limiter; Anodes; Fuel Priming Bulb - Honda BF250A Owner's Manual

Rev Limiter

The engine is equipped with a rev
limiter to prevent the possibility of
mechanical damage from excessive
engine speed.
The rev limiter may be activated
during operation, limiting engine
speed, if the outboard motor is
trimmed or tilted up excessively, or
when propeller ventilation occurs
during a sharp turn.
If the rev limiter is activated, check
the trim angle of the outboard motor.
Check to see if the correct propeller is
installed.

Anodes

ANODE

The anodes are made of a sacrificial
material that helps to protect the

There are two anodes on the gear
case, one on the stern bracket and
four small anodes in the water
passages of the engine block.
