Propeller Replacement - TOHATSU BFW 60A Owner's Manual

Propeller Replacement

Before replacing the propeller,
remove the emergency stop switch
clip from the emergency 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 spacer
(BFT60A model only), plain
washer, and then remove the
propeller and thrust washer.
2. Inspect the propeller shaft for any
fishing line or debris.
