It is recommended that you wear a pair of leather gloves
to protect yourself from sharp propeller blades. With dual
propeller units you may be able to use a piece of wood
between the top of the gear housing and the propeller to
hold it from turning while you are removing the prop
nuts and hardware to access the props. Some of these
units use 2 lock nuts, one for each propeller. You may
need a special socket and rachet set to remove the propeller
nuts. Line up the hardware according to its disassembly
for reassembly purposes. Below are drawings showing
selected propeller shaft hardware for both Volvo and
Mercruiser units. See the engine manufacturer’s owners
manual for further information.
