Propeller Replacement - Honda Marine BF75A Owner's Manual

Propeller Replacement

Before replacing the propeller,
remove the clip from the engine stop
switch to prevent any possibility of
the engine being started while you
are working with the propeller.
The propeller blades may have sharp
edges, so wear heavy gloves to
protect your hands.
Operating the outboard motor at
higher altitudes will reduce available
power. This may require decreasing
the propeller pitch to maintain correct
engine RPM.
Removal
1. Remove the cotter pin, unscrew
the castle nut, remove the washer,
then remove the propeller and
thrust washer.
2. Inspect the propeller shaft for any
fishing line or debris.
