Stuck Propeller
How do I remove a stuck propeller?
R. Dextron, Cadillac, MI
Mud motors are built to run on or near the
bottom. As such, the propeller continually
strikes objects.
The propeller is screwed on the drive and each time it hits a rock
or log it becomes tighter. So much so, that ordinary tools
will not come close to removing the blade. Removing an over-tight
propeller is actually very simple, all that is required is
leverage. Mud Buddy sells a
prop wrench set that includes extended length handles that
will loosen the most stubborn prop. You can either get a set
from Mud Buddy, or build your own.
Insert a
pipe wrench or crescent wrench into a 2 to 3 foot length of tube
to hold the rear propeller nut. Drill or punch a 3/4"
hole in a 2 to 3' length of 1 1/4" flat bar for a simple, but
effective prop wrench.
First remove the prop nuts and
clean the threads with a wire
brush. Coat
with grease or oil.
Place a pipe wrench of crescent wrench
on the rear propeller nut. Place the prop
wrench between and blades and arrange booth tools like a pair of large shears. Pull the tools toward each other and the
blade should loosen. If not, heat the hub of the prop with a
propane torch for
about 3 minutes. Do not heat the shaft,
just the prop hub. The blade should then come off. If
not add longer handles to the
tools.
Once you have removed the propeller, clean the threads with a wire brush and coat with marine waterproof grease or anti-seize compound. When installing a new propeller, if the prop is difficult to screw on, remove and clean the shaft and prop threads again. Good huntin'.
