Propeller Installation
WARNING
When installing or removing propeller, because of the engine’s ease in starting,
be sure that the remote control is in neutral position and that the key switch is
“OFF.” Place a block of wood between the anti-cavitation plate and propeller to
prevent accidental starting and to protect hands from propeller blades while re-
moving or installing nut.
1. To aid in future removal of the propeller, liberally coat the propeller shaft splines with
one of the following Quicksilver products:
-- Anti-Corrosion Grease (92-78376A6)
-- Special Lubricant 101 (92-13872A1)
-- 2-4-C Marine Lubricant (92-90018A12)
