Let us share our knowledge - use this guide to Install your propeller
Before you start, Please note that...

In order to help ensure a vibration free operation, the propeller should always be properly mated to the shaft taper. The tapers of both the shaft and propeller hub should be in contact over 75% of their surface area to transmit power effectively and without undue stress.

The following procedure is written and provided as a guideline to help
in the installation of the propeller on it's shaft.

In this procedure, it is assumed that the tapers of both the shaft and propeller are made to the same specifications and with a taper of 3/4 inches on diameter per foot.

Step 1 Remove the key from the propeller shaft. Examine it for any obvious imperfections or burrs. If necessary, file the key to correct.
Step 2 Examine both the propeller bore and the propeller shaft for any obvious imperfections or burrs. Again, correct if necessary.
Step 3 Put a smooth line of Prussian blue compound on the propeller shaft taper.
Step 4 Install the propeller on the shaft taper(ensure that the propeller is fully seated on the taper) and turn it slowly by hand, one full rotation.
Step 5 Remove the propeller and examine the blued area on both the shaft and the inside of the propeller bore. If the bluing is uniformly removed, the propeller fit is good. If not, use an appropriate lapping compound to seat the propeller to the shaft taper. Repeat steps 3 thru 5 until satisfactory contact is achieved.
Step 6 Install the propeller snugly onto the shaft taper. Please note that the key should not be in place during this step.
Step 7 Mark a thin line on the shaft at the forward edge of the propeller hub, or make an accurate measurement of the distance from the large end of the propeller hub to a strut or some other fixed point.
Step 8 Remove the propeller from the shaft.
Step 9 Re-install the key in the propeller shaft. If the propeller keyway has radiused corners please note that the key has the matching radius.
Step 10 Install the propeller snugly onto the shaft taper and check to see if the propeller moves forward to the line or measurement made in Step 7.

If it does, skip down to Step 11.
   If not, perform the following:
10 A: Hold a light near the keyway on the large end of the propeller bore. Inspect the keyway fit by checking for light around the keystock in the small end of the propeller bore.
10 B: There could be a small amount of light visible on the top of the keystock. If not, the keystock may be jamming and preventing the propeller from going back to its' original position. Remove the key, secure it in a vise, and file a small amount from the top of the keystock.
10 C: There should not be any light visible on the sides of the keystock. If there is, the keystock is under size and should not be used. The propeller could also be jamming on the sides of the keystock. To check this, carefully observe the end of the keystock as the propeller is moved up the shaft taper. Se if the keystock moves slightly to one side during the installation. If so, a very small amount should be filed from the side of the keystock in the area of contact. Another way to observe this is to check the position of the keystock after the propeller is up the taper. See if the keystock is pushed to one side or the other of the keyway. If it is, a very small amount should be filed from the side of the keystock in the area of contact.
10 D: Replace filed key in shaft keyway with filed edge on top.
10 E: Replace the propeller on the shaft and fit snugly on the taper. Check to see if it reaches the line or measurement made in Step 7. If it does not line up, repeat steps 10 A through 10 E.
Step 11 Check the fit of the propeller onto the shaft by inserting a 0.001" feeler gauge in several locations on both ends of the propeller hub. If the gauge slides in more than 1/8", then the fit may not be good. Consider using a lapping compound, and go back to Step 3 aboce.
Step 12 When the propeller hub moves to the correct position, install the propeller nut on the shaft, and torque to seat the propeller. Install the jam nut if your shaft is so equipped.
