Maintenance
Propellers
Out-of-balance and
nicked propellers will
effect performance
or cause vibration.
Damaged props should
be replaced, but those
that are chipped or bent can usually be reconditioned
by a marine dealer or a propeller repair facility. When
cruising, consider carrying a spare set of props on
board because many marinas do not carry a full
inventory of replacement propellers. Also, include
an extra set of prop hardware. Refer to the engine
manufacturer’s manual for appropriate propeller
replacement and installation assistance.
Write down the propeller diameter and pitch while
the vessel is in dry dock. They are pressed into the
prop for easy reading.
Also, note that propellers feature a rubber hub
pressed into the center propeller that includes the
hole for the prop shaft to slide through. Sometimes
as a result of impact the rubber hub becomes
damaged and the propeller will not let the boat
perform up to the rated revolutions per minute (rpm).
In an emergency a stainless propeller blade may
be straightened by laying the propeller blade on a
2 x 4 and hammering the bent portion of the blade
until straight. This normally will result in the propeller
creating a vibration and if this occurs reduce rpm
until back at mooring.
It is advantageous to carry the needed tools to
change propellers including pliers to pull cotter
key and deep socket and ratchet to remove
the propeller shaft nut. See the appropriate
outboard manufacturer’s owner’s manual for further
information.
Removing the propeller- Before removing the
propeller make sure the remote control is in neutral
and the ignition keys are removed to prevent the
engine starting and possibly causing bodily injury.
Always wear gloves when removing or installing
propellers since the component blades are very
sharp.
Note that special tools are required to remove the
DPS style propellers. Contact your nearest Regal
dealer for assistance in purchasing and procuring
these tools.
Installing propeller- Before installing parts back on
to the prop shaft make sure you lubricate the prop
shaft with the recommended lube. Again, special
tools are required for installation of propellers and
hardware. Contact your closest Regal dealer for
additional information.
On MerCruiser units, refer to your engine operation
manual or contact your closest Regal dealer for
propeller removal and installation parts, tools, and
periodic maintenance schedules and information.
