counterclockwise in order to maintain a straight
course through the water.
When removing or replacing propellers, be sure to
install the correct propeller on the correct drive.

ROPELLER NSTALLATION
For proper rotation, the installation of propellers on
inboard engine boats requires the right hand
propeller to be installed on the starboard side and
the left hand propeller to be installed on the port
side. Install in the following manner:
Step 1: Inspect shafts and propellers to ensure the
taper, keyways, keys, prop nut, jam nut and cotter
pin meet specifications. Special attention should
be paid when confirming key fit. Key must fit
snug in prop hub and propeller shaft. Key must
fit flat in bottom of both. If the key radius does
not match keyseat properly, stress risers and
catastrophic failure could occur.

• Inspect propeller(s) to ensure the bore,
diameter and pitch meet specifications for
specific engine installation (diameter and
pitch are stamped on the side of prop hub).
Step 2: Dry fit the propeller on the taper without the
key and mark the position on the shaft with a
permanent marker. The distance between the
prop and the strut shall never exceed one (1)
shaft diameter.

• Remove the propeller
and insert the key, rotate
the shaft so the key is top
dead center.
• Using a clean rag, wipe the bore of the
propeller with a small amount of penetrating
oil.
• Apply a consistent coating of Prussian blue
compound to the surface of the shaft taper.
The application should be consistent and
have a wet film thickness of 2 mils. (similar
to a light coat of polyurethane).
Step 3: Set the propeller on the
shaft and slide it up the taper with
the full nut ensuring that the
propeller hub runs up to the mark.
• Remove the propeller and inspect the
pattern transferred from the shaft to the bore
of the propeller.
• The pattern should be consistent over the
full contact area.
