REMOVING THE PROPELLER

propeller shaft.
INSTALLING THE PROPELLER
!
CAUTION
Avoid engine damage. Prop the engine so engine speed is
limited to the required full throttle rpm range. An under-propped
engine may occasionally initiate the rev limiter. This may result
in internal powerhead damage.
Mercury Racing applications use 19-spline propeller shafts and
require installation of the Heavy-Duty Propeller Hub kit, included
with most Mercury Racing propellers.
IMPORTANT: To prevent the propeller hub from corroding and
seizing to the propeller shaft, especially in salt water, always apply
a coat of Anti-Corrosion Grease to the entire propeller shaft at the
recommended maintenance intervals and also each time the
propeller is removed.
